Tachyon Deck #656121 — Yu-Gi-Oh! Duel Links

Deck — Deck Power Evaluation

Final Contextual Deck Power: 62/100 (±8 · Confidence: Medium)

• Primary strategy: Combo
• Secondary strategies: Stun, Xyz
• Format: duel-links

Legality

Main 30 / Extra 9 / Side 0 — status: Legal.

Identity & game plan

• Win condition: Dragon Xyz stacking into boss monsters: Galaxy-Eyes Full Armor Photon Dragon (4000 ATK) and Number C107: Neo Galaxy-Eyes Tachyon Dragon (4500 ATK), with Number 107 and Chaos Dragon Levianeer as additional pressure.; Hand-trap and negation control: Infinite Impermanence, Effect Veiler, Nibiru and Ghost Belle protect the engine while the Extra Deck boss closes.
• Turn 1 (going first): Open a 3-copy starter (Schwarzschild Infinity Dragon, Galaxy-Eyes Tachyon Primal, or Tachyon Cloudragon) and summon a Level 8 Dragon, then Xyz into a Galaxy-Eyes boss. Hand traps are held to protect the first summon. (Inferred)
• Turn 2 (going second): Use the 6-card hand to hold 1-2 hand traps against the opponent's first summon, then extend through Dragon Xyz stacking. Hand-trap group reaches at least one copy in 95% of going-second hands. (Inferred)
• Recovery: Recover through Starliege Seyfert and Galactic Spiral Dragon from the GY, Ghost Belle banish/recycle, and the Dragluxion searcher for Galaxy or Tachyon cards. (Inferred from card text)
• After siding: None: the deck runs 0 Side Deck cards and Duel Links does not provide a post-game side plan in this evidence.

Why it scores here

The deck reliably opens a Dragon-based starter: three copies each of Schwarzschild Infinity Dragon and Galaxy-Eyes Tachyon Primal give about a 43% chance of at least one in a 5-card opening hand, and the 14-copy archetype core group is present in 97% of 5-card hands. Its strength is in the system: 11 hand traps and 13 negation-text cards protect the engine, so interruption resilience and going-second interaction score well (Inferred, from card text and hypergeometric estimates). The Extra Deck offers a high-ATK boss package (Full Armor Photon 4000, Neo C107 4500) that gives strong closing power. Weaknesses are the absence of any combo-board data (ceiling and median are text-only inference), low archetype purity (5.1% exact-name copies, 24 generic copies), and the lack of a Side Deck. Popularity and guide praise did not earn points, and card scores were not averaged into the deck score.

Dimension scores

How the score was computed

Strategy profile: Combo. Structural ≈ 66.6, Going First ≈ 66, Going Second ≈ 71, Meta = provisional, Tournament Reliability ≈ 55. Modifiers: banlist exposure (-2). Final formula: 0.80*Structural + 0.20*TournamentReliability + ContextModifiers (Meta provisional) = 0.80*66.6 + 0.20*55 - 2 = 62.3, rounded to 62

Probability & combo summary

• Opening a starter: P(≥1) ≈ 0.43 · key two-card combo ≈ — · full-brick estimate ≈ — (all Inferred)
• Combo output: best PowerIndex —, median —, board-per-starter —
• Turn order: 0 going-first lines vs 0 going-second lines

Strengths

• Layered interaction: 11 hand traps and 13 negation-text cards protect the engine on both turns
• Strong Extra Deck boss package with verified ATK (Neo C107 4500, Full Armor Photon 4000)
• Dragon-heavy main deck (22 Dragon cards) keeps the starter pool coherent
• Full 9-slot Extra Deck used with good Xyz coverage

Weaknesses

• No Side Deck, so no post-game adaptation
• Low archetype purity: 5.1% exact-name copies and 24 generic cards
• No recorded boards, so ceiling and median are text-only inference
• Only 43% chance of a 3-copy starter in a 5-card opening hand

Critical choke points

• Galaxy-Eyes Tachyon Primal and Schwarzschild Infinity Dragon as the first summon: at 3 copies each, neither is guaranteed in hand
• A Dragon Xyz on field as the trigger for Galaxy-Eyes Tachyon Primal's hand summon

Recommended changes

Evidence & confidence

• Verified: Legal main 30 / extra 9 / side 0 under the Duel Links size rules; Limited-status cards (Seventh Tachyon, Tachyon Transmigration, Dragluxion) each run at 1 legal copy; Card text and ATK/DEF values for the deck's resolved cards; Usage-stat inclusion percentages (archetype-level)
• Inferred: Starter hypergeometric estimates (43% for a 3-copy starter in 5 cards; 95% hand-trap group going second); Interaction density and going-second strength from card text; Engine route count and recovery plan from card text; Brick risk from hand-trap and tech count
• Provisional: Matchup and format fit (D13); no dated meta or tournament data; Meta Power (null)
• Data gaps: no combos supplied: combo floor, median and ceiling are text-only inference no tournament link: archetype meta-share and per-pilot match record absent no win-rate telemetry exists in YGOVN; going-first/second and matchup rates are Inferred or Unknown Meta Power is Provisional unless a dated metagame sample is supplied Data integrity: usage statistics core cards and missing core cards flag Number 107, Number 38, Number C107, Cipher Blade Dragon, Full Armor Photon and Dragluxion as not in deck (in this deck false, copies 0), but the resolved card list includes them with copies 1 to 2. Card list treated as source of truth; core-coverage numbers are unreliable until the stats join is fixed. Deck title is null; archetype is taken from the deck record
