Sections covered in this guide:
Skill
Barian Battlemorph! Galaxy-Eyes (Skill Card) (100%)
Barian Battlemorph! Galaxy-Eyes acts as the "heart" of the Tachyon deck's entire strategy, with two extremely powerful effects that ensure both stability and finishing potential:
Right on your first turn, you are allowed to reveal one "Tachyon" card or one Tier 8 Dragon monster from your hand to directly summon Schwarzschild Infinity Dragon ( you can also summon additional Light or Dark-type Dragon monsters such as Levianeer to clear the board, or Starliege Seyfert , Nebula Dragon to further expand your combo ). This creates absolute stability, making it easy for you to execute a one-card combo to summon Tier 8 Xyz Boss monsters along with your Trap cards.
Draw Sense Ultimate (Going Second / Next Turn): On your next turn (or even on your first turn if you go second), this skill allows you to transform into Barian and ensures your draw is definitely the Rank-Up-Magic Spell Card - The Seventh One . This is the core "turnaround" card to directly summon Neo Galaxy-Eyes Tachyon Dragon , nullifying the entire board and preventing your opponent from activating any effects.
Thanks to this skill, Tachyon can easily play through interruptions (like Effect Veiler) and always has ample resources available to overwhelm opponents in subsequent turns.
Monsters in the Main Deck
Schwarzschild Infinity Dragon (x3)
This is an extremely important starter 1-card combo in the deck. Its special ability is that it can be activated directly from your hand to Special Summon along with another Dragon from your deck (usually Galactic Spiral Dragon ) if you don't have any monsters or your opponent has monsters with 2000 or more attack power. Because this effect activates in your hand, it can be easily dodged. Opponent's Effect Veiler .
Galactic Spiral Dragon (x1)
This monster is often summoned directly from the deck thanks to the effect of Infinity Dragon . It acts as a plentiful Xyz material because it can revive itself from the Graveyard to the field. Additionally, it has the effect of leveling up other monsters on the field (such as Starliege Seyfert ) to Level 8, making it easier to perform Rank 8 Xyz Summons.
Tachyon Cloudragon (x2)
This is a combo expansion piece, often acquired by Number 46: Dragluon . When added to hand by card effect, Cloud Dragon can Special Summon itself. Its primary effect is to sacrifice itself to summon. Galaxy-Eyes Tachyon Primal is from the deck. Additionally, when in the Graveyard, it can attach itself to one of your Xyz monsters for material.
Galaxy-Eyes Tachyon Primal (x3)
The core monster's mission is to find and protect resources. When summoned to the field (via Cloud Dragon or from your hand), it will help you find any "Tachyon" cards (usually Counter Trap Tachyon Transmigration ). A great strategy is to keep this card in your hand and Special Summon it right into your opponent's Draw Phase to both take the trap and avoid the risk of getting hit by Nibiru during your turn.
Starliege Seyfert (x1)
This is a monster often used for Normal Summoning when you need to deal with interruptions like Effect Veiler . Seyfert can Tribute another Dragon on the field (like Spiral Dragon) to summon Tier 8 Dragons (like Tachyon Dragon or Nebula Dragon) from your deck to your hand, helping you maintain combo rhythm without fear of getting stuck.
Nebula Dragon (x1)
A versatile Extender, often acquired through Seyfert or Deck Abilities, Nebula Dragon allows you to Special Summon itself along with another Tier 8 Dragon from your hand to the field, creating a fast path to spam Tier 8 Xyz monsters.
Chaos Dragon Levianeer (x1)
Although it's a Tech monster (optional), it's touted as an extremely powerful board-clearing weapon when going second. Thanks to Barian's Battlemorph skill , you can easily acquire this Dark/Light Dragon and use its destructive effect to crush your opponent's board before delivering the finishing blow.
Spell/Trap
Tachyon Transmigration (x1)
This is the core power card that makes Tachyon such a formidable force. It's a Counter Trap that can be activated directly from your hand if you control a " Galaxy-Eyes Tachyon Dragon " monster. Its ability is incredibly powerful: it negates all of your opponent's effects within the same Chain and shuffles all those cards back into their deck. This is a non-targeted, non-destructive removal type, effectively clearing out any threat.
Tachyon Spiral Galaxy (x3)
Acting as an absolute shield, this trap card can also be activated from your hand if you have " Galaxy-Eyes Tachyon Dragon ". When activated, it makes your Galaxy-type Dragon monster invulnerable: unaffected by card effects and unkillable in battle. Using this card helps you preserve your main monster without wasting Transmigration too early, saving the disable from your opponent's powerful moves.
Seventh Tachyon (x1)
This is a Spell card that functions to search for resources to increase stability or create a follow-up move. It helps you draw important monsters like Infinity Dragon , Starliege Seyfert , or other support cards into your hand to ensure your combo doesn't break.
Rank-Up-Magic - The Seventh One (x1)
Guaranteed to be drawn by Skill when going second or on the next turn. When activated at the start of Main Phase 1, it allows you to Special Summon " Galaxy-Eyes Tachyon Dragon " from the Extra Deck or Graveyard, and then instantly Rank Up it to " Neo Galaxy-Eyes Tachyon Dragon " to finish the match.
Tech/Staple
The goal is to disrupt the match or force the opponent to use their effects before entering Main Phase 1, ensuring that Rank-Up-Magic - The Seventh One can be successfully activated without interruption.
Extra Deck
Divine Golden Shadow Dragon Dragluxion (x1)
Serving as a conduit and core combo expansion tool, when Xyz Summoned with two Tier 8 monsters, it allows you to search for any "Tachyon" card. More importantly, by splitting the two materials, it can directly summon "Tachyon Dragon" or "Titanic Galaxy" from the Extra Deck and directly attach a monster from the Extra Deck (such as Galaxy Satellite Dragon) as material for them.
Number 107: Galaxy-Eyes Tachyon Dragon (x2)
As the foundational boss of the deck, the presence of this card on the field is essential for activating powerful trap cards like Tachyon Transmigration or Tachyon Spiral Galaxy directly from your hand. Besides applying initial pressure, in subsequent turns it also serves as a "stepping stone" for materials to upgrade to stronger Xyz forms, helping to clear the board.
Number C107: Neo Galaxy-Eyes Tachyon Dragon (x1)
The "Destruction" card offers the ultimate finishing power. It's often summoned incredibly easily via the Rank-Up-Magic spell card - The Seventh One . This monster can detach an ingredient to negate all other cards on the field and prevent the opponent from activating any card effects. Once this effect is successful, the opponent is completely locked down and unable to retaliate.
Number 38: Hope Harbinger Dragon Titanic Galaxy (x1)
This is a solid defensive wall against your opponent's Spell cards. It provides a Spell Disable, helping to keep the board safe without wasting valuable Trap cards from your hand. Additionally, it can force your opponent to redirect their attack towards it, and if another of your Xyz monsters is destroyed, it can stack that monster's attack power onto another Xyz monster, making it very difficult for your opponent to break through the defense.
Galaxy Satellite Dragon (x1)
This Link Monster is special because it's not normally summoned but is "attached" directly from the Extra Deck as material for an Xyz Monster thanks to the Dragluxion effect. When detached and sent to the Graveyard, its effect activates during the Battle Phase, increasing your "Number" Monster's attack power by 100 times its number (reaching 10,700 ATK for Number 107), dealing massive OTK damage.
Number 46: Dragluon (x1)
The ultimate (Tech card) is used to counter decks that rely on Dragon monsters (such as Branded or Mirror Match Tachyon). By discarding the material when it's the only monster you control on the field, it completely disables the ability of any of your opponent's Dragon monsters to activate their effects until the end of the next turn. This move acts as a "death blow," completely depriving your opponent of any playable ability.
Galaxy-Eyes Full Armor Photon Dragon (x1)
This is a powerful board-clearing tool for later turns. You can easily summon it by placing it directly on top of "Galaxy-Eyes Tachyon Dragon". This monster can split a material to instantly destroy one of your opponent's face-up cards, quickly eliminating obstacles or your opponent's Bosses.
Galaxy-Eyes Cipher Blade Dragon (x1)
Serving as a follow-up board clear, this monster is summoned by placing it directly on top of Full Armor Photon Dragon. It allows you to detach a material to destroy ANY card on the field (including face-down cards), helping to clear any remaining back-row threats or defensive monsters before your full-force attack.
