Tachyon Deck #755475 — Yu-Gi-Oh! OCG

Deck — Deck Power Evaluation

Final Contextual Deck Power: 58/100 (±6 · Confidence: Medium)

• Primary strategy: Combo
• Secondary strategies: Midrange, Stun
• Format: ocg

Legality

Main 40 / Extra 15 / Side 0 — status: Legal.

Identity & game plan

• Win condition: Xyz Summon a Galaxy-Eyes or Tachyon Xyz (Number 107 / C107 / Number 62 / Full Armor Photon Dragon) and attack through a negated or cleared board; Regenesis 2500-ATK beatsticks and Bystial Lubellion pressure once the Extra Deck line is stalled
• Turn 1 (going first): Open with a searcher (Seventh Ascension, Regenesis, Regenesis Archfiend) into a 2500-ATK enabler, then reach a Galaxy-Eyes or Tachyon Xyz; hold Ash Blossom, Infinite Impermanence and Maxx C for the first interruption
• Turn 2 (going second): Use the six-card hand's hand traps (Ash, Ghost Belle, Impermanence, Transmigration, Droll & Lock Bird) to blank the opponent's first summon or search, then rebuild through Regenesis recursion
• Recovery: Regenesis Birth and Regenesis Sage recover 2500-ATK bodies from the GY; Tachyon Spiral of Destruction and the Galaxy Xyz materials supply follow-up
• After siding: Not applicable: the export shows a 0-card Side Deck, so there is no sided plan to evaluate

Why it scores here

The deck has a reliable entry point: P(at least one searcher in an opening 5) is about 0.94 and P(at least one of the 7 archetype-core copies) is about 0.64, so the Regenesis and Galaxy-Eyes lines usually come online by turn 2 (Inferred). Its ceiling comes from the Extra Deck, with Number 107, C107, Number 62 and Full Armor Photon Dragon reaching 3000 to 4500 ATK and carrying negates. Interaction is the strongest part of the system: eight hand traps plus several Xyz negates give the deck layered answers to a first-turn play. Its median is held back by a split engine (Regenesis, Galaxy-Eyes, Seventh, Archfiend, Mulcharmy, Bystial share a list with only 2 exact-name Tachyon copies) and a 36% estimated brick rate for the core set. No recorded boards exist, so the scores rest on card text and hypergeometric estimates, not observed results. Popularity did not earn points, and the score was not built by averaging card scores.

Dimension scores

How the score was computed

Strategy profile: Combo. Structural ≈ 63, Going First ≈ 60, Going Second ≈ 64, Meta = provisional, Tournament Reliability ≈ 55. Modifiers: Engine conflicts (-3); Banlist exposure (-1). Final formula: 0.80*Structural + 0.20*TournamentReliability + ContextModifiers (Meta provisional; 0.80*63.4 + 0.20*55 - 4 = 57.7 -> 58)

Probability & combo summary

• Opening a starter: P(≥1) ≈ 0.64 · key two-card combo ≈ — · full-brick estimate ≈ 0.36 (all Inferred)
• Combo output: best PowerIndex —, median —, board-per-starter —
• Turn order: 0 going-first lines vs 0 going-second lines

Strengths

• Searcher density (16 cards, P≥1 in 5 ≈ 0.94) makes the deck reliably start a plan on turn 1
• Eight hand traps plus Xyz negates give layered interaction against a single opposing turn-1 play
• Number 107, C107, Number 62 and Full Armor Photon Dragon reach 4000-4500 ATK for closing

Weaknesses

• Split engine across Regenesis, Galaxy-Eyes, Seventh, Archfiend, Mulcharmy and Bystial lines lowers coherence
• Core set absent from about 36% of 5-card hands by the hypergeometric proxy
• No Side Deck, so no post-side plan

Critical choke points

• Extra Deck Xyz summon depends on finding a Galaxy-Eyes or Tachyon Level 8 or 9 material base
• Regenesis 2500-ATK enablers are needed to unlock Archfiend, Warrior, Sage and Dragon; a miss stalls the Regenesis line

Recommended changes

Evidence & confidence

• Verified: Legal OCG list: 40 Main, 15 Extra, 0 Side, no violations; Five Limited singletons and Ash Blossom at 2 copies (Semi-Limited) match the OCG banlist field; Usage core present: 4 of 11 core cards (36.4%)
• Inferred: Searcher and archetype-core probabilities from the hypergeometric draw table; Combo ceiling from Xyz enablers and negate text; Interaction density from negate, removal and hand-trap text; Going-second hand-trap probability ≈ 0.76
• Provisional: Meta Power (null) and D13 matchup fit require a dated metagame sample
• Data gaps: No combos supplied: combo floor, median and ceiling are text-only inference No tournament link: archetype meta-share and per-pilot record absent No win-rate, brick, starter or OTK telemetry exists in YGOVN Side Deck is empty, so D12 and post-side plans cannot be assessed from data Meta Power is Provisional without a dated metagame sample
