Overview

Drytron is a Machine- type, Light- type archetype that focuses entirely on Ritual Summon mechanics, but in a unique and unprecedented way: using Attack Power (ATK) as materials instead of Level.

Instead of large monsters, the core of Drytron consists of Level 1 monsters with 2000 ATK . They cannot be Normal Summoned but must be Special Summoned from your Hand or Graveyard by Tributing other Drytrons. This creates an endless resource-driven gameplay, turning your Graveyard into a "second deck".

1. Deck Mechanism:

Unlike traditional Ritual decks that require sacrificing monsters with a total Level (Star Rank) equal to or higher than the target monster, Drytron is a collection of Light-type Machines that use Attack Power (ATK) as a material.

Level 1 Frame: All of Drytron's Main Deck monsters are Level 1 but possess 2000 ATK . They cannot be Normal Summoned but must be Special Summoned by Tributing another Drytron (from your hand or field).
Perpetual Ritual Spell: The soul card Meteonis Drytron allows you to summon any Ritual monster (as long as the ATK of the materials is greater than or equal to the ATK of the Ritual monster). Most terrifying aspect: This card can repeatedly recall itself from the Graveyard each turn by reducing the ATK of a Drytron on the field by 1000.

=> Consequence: You'll never have to worry about "running out of ammo." The Graveyard becomes your second deck. A spell card can be used multiple times, a monster can die and respawn repeatedly.

2. GAMEPLAY & TACTICS:

Drytron's playstyle is best described by the phrase: "Never Stop Special Summoning."

Exploiting the Cyber Angel Benten Engine: Drytron thoroughly abuses the capabilities of the Cyber Angel Benten . Because Benten's search effect is "unlimited per turn," Drytron players will repeatedly sacrifice Benten in a single turn to fill their hand with crucial pieces such as:
- Diviner of the Herald: To Synchro/Xyz or send the song to the graveyard.
- Magikey Mechmusket - Batosbuster: To set up a trap to negate spells/traps.
- Mikanko Ohime: To assist in OTK or field destruction.
The Power of Variety:
- Go First: Build "Impregnable Fortresses" with multiple layers of interruptions such as I:P Masquerena (transforms into Underworld Goddess to impale enemy monsters), Herald of the Arc Light (Omni-negate), or Magikey Unlocking .
- Going After: Drytron possesses Boss Monsters with devastating destructive power:
  - Drytron Meteonis Quadrantids: Clears all of the opponent's Spells/Traps (Harpie's Feather Duster comes to life).
  - Drytron Meteonis Draconids: 4000 ATK, cannot be targeted, attacks all special monsters and banishes your opponent's cards.

3.SKILL:" STARRY SLUMBERING MEMORIES"

In Duel Links, Drytron is empowered by his unique skill , Starry Slumbering Memories .

Increase stability: Transform a bad (Brick) hand into a smooth combo by exchanging 1 Drytron in your hand for 1 Ritual piece from your deck, and simultaneously burying 1 Drytron in your graveyard (sets up graveyard immediately).
Field-clearing support: When going second, this skill allows you to search for Spell/Trap Drytron (such as Asterism to detonate cards or Nova to summon more minions), making it easier to overcome your opponent's obstacles.

4. CRITICAL WEAKNESSES & CHALLENGES

Despite his strength, Drytron is not invincible. Players need to be aware of his three biggest enemies:

Droll & Lock Bird: Because this deck relies on continuous card searching, this card is a hard counter, immediately stopping your turn.
Nibiru, the Primal Being: With over 15 summons per turn, you're always in the sights of "The Stone". (While you can search Sauravis to counter it, it remains a constant threat).
Time Limit Pressure: This is the most realistic factor in Duel Links. Drytron's combos are very long and require many button presses. Winning the game but losing due to "Time Out" is a common pain for new players getting acquainted with this deck.

DRYTRON LEVEL 1 GROUP (CORE ENGINE)

The common characteristic of these cards is that they are all Level 1, ATK 2000 / DEF 0.

These monsters share a common mechanism: They cannot be Normal Summoned. They must be Special Summoned (from Hand or Graveyard) by Tributing another Drytron or a Ritual Monster from Hand/Field.

Note : You can use this effect to summon them from the Graveyard, allowing for unlimited resource reuse.

Drytron Alpha Thuban (x2-3)

The starter leaf is the most important.

Effect: When summoned, add 1 Ritual Monster from your Deck to your hand.

How to use: Usually used to search for Cyber Angel Benten . This is the most basic combo: Sacrifice Benten to summon Alpha -> Alpha search for the new Benten (or Boss) + the old Benten that was sacrificed search for Diviner of the Herald .

Drytron Zeta Aldhibah (x3)

The second most important starter.

Effect: When summoned, add 1 Spell Ritual (Meteonis Drytron) from your Deck to your hand.

Make sure you always have Spells available to perform Ritual Summon. If you already have a Spell, Zeta will help you retrieve it to ensure the combo isn't interrupted.

Drytron Gamma Eltanin (x2-3)

Extender (combo extender) and helps to deepen the flow.

Effect: When summoned, target 1 Drytron (2000 ATK) in the Graveyard and Special Summon it.

This card instantly brings 2 monsters onto the field (Gamma + revived monster) to Link Summon or Xyz Summon Drytron in Mu Beta Fafnir . This card helps to dramatically increase the number of monsters on the field.

Drytron Delta Altais (x2)

Deck drawing machine.

Effect: When summoned, you can reveal 1 Ritual Monster/Spell in your hand -> Draw 1 card .

It helps you delve deeper into the deck to find missing pieces (tech cards, hand traps) or simply gain a card advantage.

Drytron Beta Rastaban (x0-1)

Recycler (Resource Recycling).

Effect: When summoned, return 1 Banished Drytron to the Graveyard.

This card is played less frequently than its counterparts (usually 0-1 card played). It's used in extended matches (Grind Games) when resources in the graveyard are depleted or the player is banished by an opponent.

SUPPORT MONSTER GROUP

Cyber Angel Benten (x3)

Deck's Perpetual Motion Engine

This is the MVP of the deck; my "fuel" never runs out.

Effect: When Tributed (by Drytron or Ritual Spell), add 1 Light-type Fairy monster from your Deck to your hand.
Why is it so overpowered? This effect has no limit on the number of uses per turn . You can sacrifice Benten A to search for Benten B, sacrifice Benten B to search for Benten C, or other puzzle pieces.

Diviner of the Herald (x0-2)

This card is: Tuner / Searcher / Combo Piece, and it can also be searched using Cyber Angel Benten .

Effect: When summoned, send 1 Fairy from your Deck/Extra Deck to the Graveyard (usually Herald of the Arc Light ) to increase its Level.

Combo: Sending Arc Light to the graveyard allows you to search for an additional Ritual Monster/Spell. Additionally, it becomes Level 6, which can be combined with Drytron (Level 1) or Benten (Level 6) for a customizable Synchro/Xyz summon.

Magikey Mechmusket - Batosbuster (x0-1)

Ritual Monster Sub-Set / Searcher Trap.

Effect: When Ritual Summoned, add 1 "Magikey" card from your deck (Takes Magikey Unlocking ).

Drytron summons this monster easily thanks to its unique Ritual mechanism. It allows you to set up an Interruption layer by searching for Counter Traps to negate your opponent's Spell/Trap cards. It completes the missing piece for Drytron when Turn 1. While Drytron is strong at destroying monsters, Batosbuster helps protect your base from dangerous Spell/Trap cards (such as Dark Hole , Book of Moon ).

Mikanko of the Oohime (x0-1)

Easy to Search: As a Fairy/Light monster, it can be searched for free using the Cyber Angel Benten effect .
"Zero-cost" summoning: Because she has 0 ATK , you spend very few resources to summon her using Meteonis Drytron (sacrifice just one Drytron child).
4000 LP Assassin: In Duel Links (4000 base points), Ohime's damage reflection effect combined with Drytron's 4000 ATK monster creates an absolute win formula (OTK), regardless of how strong the opponent's monster is in attack position.

These three reasons make this card very suitable for playing with Drytron.

Manju of the Ten Thousand Hands (x0-1)

Support is available for all Ritual players, but personally, I don't find it very necessary for Drytron Duel Links.

Boss Ritual Drystron

Despite being Level 12 (the highest level), thanks to Meteonis Drytron 's special ATK mechanism, you only need to Sacrifice 2 small Drytron monsters (2000 + 2000 = 4000 ATK) to easily summon them. Both possess 4000 ATK / 4000 DEF .

Role Division:

Facing an opponent playing monster/combo (Link, Xyz, Synchro) -> Use Draconids .
Facing an opponent using Backrow (Traps, perpetual magic) -> Use Quadrantids .

Interacting with Meteonis Drytron: Since the Ritual spell can reduce the Boss's ATK (from 4000 to 3000) to retrieve it, you can summon the Boss, reduce its attack to get the spell back, and then immediately summon a second Boss in the same turn.

Drytron Meteonis Draconids (x1)

The main boss to defeat when you go first (Turn 1) or to clear out enemy monsters.

This card cannot be targeted by your opponent's Monster Effects . It can attack all Special Summoned monsters your opponent controls (one at a time). With 4000 ATK, it can wipe out your opponent's board during the Battle Phase.

Quick Effect: During your opponent's turn (if your total monster ATK in the graveyard is >= 2000 or 4000), you can banish Drytrons from the graveyard to target one of your opponent's face-up cards and Send it to the graveyard .

Note: The "Send to the Graveyard" mechanism is stronger than "Destroy" because it overcomes monsters with destruction resistance.

This is the card you want to leave on the field at the end of the first turn, as it provides an interruption during your opponent's turn (to play one card).

Drytron Meteonis Quadrantids (x1)

It's a board-breaking tool when going second or facing a deck with many traps.

This wife cannot be targeted by enemy Spells and Traps . When Ritual is summoned: You can destroy all Spells/Traps controlled by your opponent (similar to Harpie's Feather Duster ).

Additionally, it has a Floating ability: If this card is destroyed (by battle or effects), you can Special Summon Drytron monsters from the Graveyard (total ATK equals 4000). This prevents you from being "left on the field" if your opponent defeats it.

Use this card when you see your opponent has many face-down cards. Summon it, sweep the back row, and use its 4000 ATK to strike directly at the opponent's base.

Spell/Trap

Meteonis Drytron (x1)

This is the most important card, the one that sets Drytron apart from the rest of the Ritual world.

Unique Mechanism: Use the Attack Power (ATK) of your Machine Monsters as a Tribute instead of Level. This allows you to summon high-level Ritual Monsters (even Level 12) by sacrificing just 1 or 2 Drytrons (2000 ATK).
Variety Summon: You can summon any Ritual Monster (Drytron, Herald, Magikey, Mikanko...), as long as you have enough ATK.
Infinite Loop: While in the Graveyard, you can target 1 Drytron on the field, reducing its ATK by 1000 to retrieve that card .
- Strategy: Thanks to this ability, you only need to play 1-2 cards from the deck but can use it an unlimited number of times in a game.

Drytron Fafnir (x1)

This card increases stability and provides protection for the combo.

Search: When activated, you add 1 Spell/Trap Drytron from your Deck to your hand (usually Nova to expand your combo or Asterism to disrupt the field).
Absolute Protection: While this card exists, the activation and effects of Ritual Spells cannot be negated . This is extremely important when facing decks with many Negates, ensuring your Boss monster is definitely landed on the field.
Skill Interaction: This is the top priority for skill-based searches when following a lead.

Drytron Nova (x1)

Effect: Special Summon 1 Drytron monster from your Deck, but it will be destroyed at the end of your turn.

Uses:

Call for additional materials to perform a Link Summon or Xyz Summon ( Mu Beta Fafnir ).
Summon more "corpses" to use as Sacrificial offerings for the Ritual Summon.
Since Drytron wants to stay in the Graveyard, destroying it at the end of your turn or using it as Link material will help you set up the Graveyard for the next turn.

Drytron Asterism (x0-1)

Effect: Target 1 Drytron you control, reduce its ATK by 1000 to Destroy 1 of your opponent's face-up cards.

Because it 's a Quick-Play Spell, you can use it during your opponent's turn to interrupt their combo or use it when you're second to clear the way for the Boss to attack.
Note: This can be searched using Drytron Fafnir .

Drytron Meteor Shower (x0-1)

Effect: When your opponent Normal or Special Summons a monster, if you control a Ritual monster: Disable that Summon and shuffle that monster back into your deck.

Role: A very powerful Interruption class when going first. However, because it's a Trap, it's slow, usually only played as a single card if the meta requires it.

Cyber Emergency (x0-2)

This card searches for the monster Drytron. If negated, you can retrieve it to your hand. Use it to maximize deck stability.

Magikey Unlocking (x0-1)

Searched for by Magikey Batosbuster . Used to disable your opponent's Spell/Trap cards, protecting your field from cards like Dark Hole or Book of Moon .

Skill

Starry Slumbering Memories (Skill Card) (100%)

I. SKILL EFFECTS (DETAILS)

This skill comprises three main parts:

1. Passive conditions (Restriction):

You cannot Normal Summon any monsters except for Light- type monsters.
You cannot Special Summon any monsters except Drytron or Ritual monsters.
- Exception: Monsters from the Extra Deck (such as Mu Beta Fafnir , Lyrilusc , Link Monsters ) are not limited by this.

2. Activation Effect 1 (Consistency - Increased Stability):

Condition: Reveal 1 Level 1 Drytron monster in your hand.
Perform:
1. Add 1 Ritual Monster or 1 Ritual Spell "Meteonis Drytron" from your Deck to your hand.
2. Next, send 1 Level 1 Drytron monster from your Deck to the Graveyard.
Limitations: Each Duel can only be used once (for effects 2 and 3, but these effects are usually used on Turn 1).

3. Activation Effect 2 (Going Second / Board Breaking):

Condition: If your opponent is controlling a monster (usually used when going second).
Action: Add 1 Drytron Spell or Trap card from your deck to your hand.
Common targets: Drytron Fafnir (Environment), Drytron Nova (Summon additional monsters), or Drytron Asterism (Explode cards).

II. WHY IS THIS SKILL SO OVERPOWERED?

1. Transform "Brick" into "Combo" (Unbricking): Drytron needs 2 pieces to begin: 1 Drytron + 1 Ritual (to be sacrificed).

If you only have Drytron and no Ritual Monsters -> Skill exchanges 1 Drytron for 1 Ritual Monster (usually Cyber Angel Benten ).
If you only have Ritual weapons and no Drytron, the skill won't activate (this is a minor weakness), but since you play a lot of Drytron, this chance is low.

2. Set up the Graveyard immediately (Free Foolish Burial): "Sending 1 Level 1 Drytron from your Deck to the Graveyard" is extremely important.

You can send Drytron Gamma Eltanin (to revive monsters), Zeta (to get spells), or Alpha (to summon monsters) depending on what you're missing in your hand.
It turns the Graveyard into a resource right from the first turn without needing to use any cards (like Foolish Burial ).

3. The advantage of Going Second: The Drytron Spell/Trap effect helps you disrupt your opponent's strategy.

Take Drytron Nova : Summon 1 free monster to the field -> Force your opponent to use a Bait effect.
Use Drytron Asterism : Instantly reveal one of your opponent's cards.
Take Drytron Fafnir : Counteracts Ritual Spell disables, ensuring the Boss lands safely on the field.

III. TACTICS FOR USING SKILLS (SAMPLE COMBOS)

Scenario: You have a "Drytron Alpha Thuban" in your hand.

Skill Activation: Alpha Thuban Reveals Himself.
- Add Cyber Angel Benten to your hand.
- Send Drytron Zeta Aldhibah to the Tomb.
Combo:
- Using Alpha Thuban (in hand): Sacrifice Benten -> Summon Alpha + Search for a second Benten (or Ritual Boss).
- Benten Effect (recently sacrificed): Search Diviner of the Herald (or another fragment).
- Use Zeta Aldhibah (from the Graveyard): Sacrifice the second Benten -> Summon Zeta + Search for Meteonis Drytron .
Result: From 1 card + Skill, you have 2 monsters on the field (Alpha, Zeta) + Ritual spell in hand + Abundant resources to continue Link/Xyz or Ritual Summon.

Important note:

This skill allows you to Normal Summon Diviner of the Herald (since it's a Light-type). This is a subtle detail that helps the deck work smoothly with Synchro/Xyz plays.
You cannot play hand traps of other types (like Droll & Lock Bird - Wind, Ash Blossom - Fire) if you intend to Normal Summon them, but Drytron doesn't usually Normal Summon hand traps, so it's not a major issue. However, it does prevent you from playing tech monster cards other than Light/Drytron/Ritual in your Main Deck if you want to Special Summon them.

Extra Deck

Drytron Mu Beta Fafnir (x2)

The heart of the Extra Deck is Drytron Mu Beta Fafnir , this Archetype's exclusive Rank 1 Xyz monster. It's considered an indispensable piece in every starting combo. When Xyz Summoned, Mu Beta Fafnir immediately sends a Drytron card from your Deck to the Graveyard, acting as a second "Foolish Burial" alongside your Skill, ensuring you always have enough resources in the Graveyard to revive. Beyond just setup, it also helps preserve your hand resources by splitting Xyz materials to replace the sacrificial item during Ritual Summons.

In particular, when you control a Machine-type Ritual monster, Mu Beta Fafnir becomes a solid shield with the ability to neutralize the activation of your opponent's Magic or Trap abilities, protecting the battlefield from potential threats.

Herald of the Arc Light (x1)

Besides the power of Xyz, Drytron also fully utilizes the Synchro mechanism through Herald of the Arc Light . Although Drytron is a collection of Level 1 monsters, thanks to Diviner of the Herald (a Tuner that can level up), summoning Arc Light becomes extremely easy. This card provides a powerful "Omni-negate" disruption layer, capable of blocking any Spell, Trap, or Monster Effect by sacrificing itself.

Interestingly, when Arc Light is sent to the Graveyard (whether by sacrifice or sent from the Extra Deck by a Diviner), it activates an effect that searches for a Ritual Spell or Ritual Monster, maintaining the player's post advantage even after losing monsters on the field.

Link monster

Drytron's attack power and field-clearing ability are amplified by its versatile Link monsters. At lower levels, Linkuriboh is a basic tool for sending Drytrons summoned by Drytron Nova to the Graveyard to reuse their effects.

When it comes to disrupting an opponent's formation, the Knightmare Phoenix and Knightmare Unicorn duo are top choices for eliminating specific threats.

However, the brightest star among the Link monsters is Underworld Goddess of the Closed World . With Drytron's ability to "spam" monsters indefinitely, summoning this Link-5 is well within her grasp. She can use an opponent's monster as a summoning material (similar to Kaiju), eliminating "invincible" monsters or the most annoying bosses, and disabling all effects on the opponent's field, making her the ultimate weapon to finish the game when going second.

Lyrilusc - Assembled Nightingale and Lyrilusc - Ensemblue Robin (x1)

Additionally, if defense is needed, Lyrilusc - Assembled Nightingale is also a great Rank 1 Xyz pick to "buy time," helping you survive your opponent's attack thanks to its indestructibility and damage-blocking abilities.

Combo & How to Play

The core gameplay of Drytron doesn't follow a monotonous linear path but rather resembles an eternal resource loop, where the lines between Hand and Graveyard are blurred. The most important strategic thinking when using this deck is "resource management": you never want to end your turn without gaining a significant number of cards. The heart of this machine lies in the relentless abuse of Cyber Angel Benten 's "unlimited uses per turn" effect . By repeatedly sacrificing Benten through the effects of Drytron monsters, you continuously acquire crucial pieces like Diviner of the Herald or Magikey Batosbuster to expand your position. The ultimate goal isn't just to summon a Boss, but to set up a board capable of controlling (when going first) or completely destroying (when going second) while maintaining, or even increasing, the number of cards in your hand for the next turn.

I. STRATEGIC THINKING (MINDSET)

Before you start your combo, remember Drytron's three golden rules:

Benten Loop: Cyber Angel Benten has no limit on the number of times it can be activated in a turn. Sacrifice it repeatedly as many times as possible to get the card (Search).
The Graveyard is a Resource: Don't hesitate to send your Drytrons down to the Graveyard. They're just as useful down there as they are in your hand.
Spell Ritual Management: Meteonis Drytron can return to your hand. Always plan to reduce a monster's ATK by 1000 and retrieve this spell for your next summon.

II. BASIC COMBO (Turn 1 - Go First)

Step 5 (Finishing - OTK):
- Summon Mikanko Ohime (if playing) or Boss Drytron with 4000 ATK.
- Directly attack or punch your opponent's attacking monster to deal 4000 damage.

V. IMPORTANT NOTES WHEN CHOOSING COMBOS

Chain Order: When Fafnir is summoned in Mu Beta , if you have other trigger effects (e.g., Benten), arrange the chain so that the important effect is not blocked by your opponent.
Card placement: In Mu Beta, Fafnir should be placed in the Extra Monster Zone to leave 3 Main Monster Zone slots for 3 other Drytron/Ritual monsters (because Drytron needs space to summon).
Time: Drytron's combo is very long. Act decisively. If time is running out, prioritize summoning a large boss monster (Draconids) and leave 1-2 Drytrons in your graveyard/hand for the next turn instead of trying to use the entire combo.
