Tachyon Deck #771815 — Yu-Gi-Oh! OCG

Deck — Deck Power Evaluation

Final Contextual Deck Power: 32/100 (±12 · Confidence: Low)

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

Legality

Main 53 / Extra 17 / Side 0 — status under the rules at evaluation time: Illegal. 3 violation(s).

Identity & game plan

• Win condition: Extra Deck Synchro/XYZ beaters (P.U.N.K. JAM Dragon Drive, Psychic End Punisher, Chaos Angel, Angelechy Shatranga/Bastion) reached through Synchro and P.U.N.K. recursion, not through the Tachyon core the archetype label implies; Angelechy Field Spell chain (Opening to e4, Problem, Endgame Problem) producing Continuous-Spell Synchro beats
• Turn 1 (going first): Open P.U.N.K. Tuners (Noh-P.U.N.K. Ze Amin / Gagaku Wa Gon) with search effects, Synchro into a 2800-3500 ATK boss; hand traps held for the opponent's first activation
• Turn 2 (going second): Hold Ash Blossom, Ghost Belle, Ghost Ogre, Droll & Lock Bird and Effect Veiler against the opponent's Main Phase to blank the first engine, then rebuild through Synchro from the GY
• Recovery: Foolish Burial Goods and Noh-P.U.N.K. Deer Note / Foxy Tune recursion; Angelechy Verdict and Disturbance recur from the GY
• After siding: No side deck is registered; no post-side plan can be evaluated

Why it scores here

This list is illegal in OCG: three copies each of Ash Blossom & Joyous Spring and Foolish Burial Goods exceed their Semi-Limited limit of two, and the Extra Deck holds 17 cards against a maximum of 15. The score is therefore a structural-only read, capped in the low range and not a normal final rating. Structurally the deck is a P.U.N.K./Angelechy/Mulcharmy Synchro shell with 12 hand traps and 11 negation-text cards, so it can interrupt the opponent's first activations and then rebuild through Synchro from the GY. Its reliable part is interaction density; its weak part is the engine, because the 'Tachyon' archetype label does not match the card pool (exact-name purity 0%, only 3 of 16 standard Tachyon core cards present) and no recorded boards or guides exist to confirm the Synchro lines. Popularity did not earn points, and card scores were not averaged into the deck score.

Dimension scores

How the score was computed

Strategy profile: 100/0 Midrange weights; Stun considered qualitatively only. Structural ≈ 44, Going First ≈ 45, Going Second ≈ 55, Meta = provisional, Tournament Reliability ≈ 35. Modifiers: Copy-limit violation (-6); Extra Deck size violation (-4). Final formula: 0.80*Structural + 0.20*TournamentReliability (Meta provisional) + ContextModifiers; 0.80*44 + 0.20*35 = 42.2, then -10 modifiers = 32, Illegal so theoretical/structural-only

Probability & combo summary

• Opening a starter: P(≥1) ≈ 0.26 · 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

• Hand-trap density (12) gives strong going-second interaction, about 80% to hold one in the 6-card hand
• Multiple 3000-3500 ATK Synchro bosses with banish or negate effects
• Interaction breadth: 15 removal-text and 11 negation-text cards

Weaknesses

• Illegal in OCG: copy-limit and Extra Deck size violations
• No Tachyon core: exact-name purity 0%, 3 of 16 standard core cards present
• Low consistency: 0.26 for a 3-copy starter in opening 5; the deck runs at least 6 distinct engines
• No side deck, so no post-side adaptation

Critical choke points

• Extra Deck legality: 17 cards must drop to 15 before the list is playable
• Ash Blossom and Foolish Burial Goods at 3 copies break the Semi-Limited rule

Recommended changes

Evidence & confidence

• Verified: OCG legality: 3 copies of Ash Blossom and Foolish Burial Goods exceed the limit of 2; Extra Deck 17 > 15; Droll & Lock Bird and Harpie's Feather Duster are Limited at 1 copy and are legal; Card text excerpts and archetype labels for all listed cards
• Observed: Usage stats list the Tachyon core (Galaxy-Eyes / Number 107 / Number 38 family) at 55-78% inclusion; this list has 3 of 16 present
• Inferred: Opening-hand probabilities (hypergeometric); Hand-trap interaction density and going-second strength; Brick and consistency estimates
• Provisional: Matchup and format fit (no dated meta sample, no archetype share); Meta Power (null)
• Data gaps: no combos supplied; combo floor/median/ceiling is text-only inference no tournament link; archetype meta-share and per-pilot match record absent no win-rate telemetry (going-first/second, matchup, brick/starter rates) no side deck registered deck title is null Meta Power is Provisional without a dated metagame sample
