Tachyon Deck #761273 — Yu-Gi-Oh! OCG

Deck — Deck Power Evaluation

Final Contextual Deck Power: 50/100 (±8 · Confidence: Medium)

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

Legality

Main 54 / Extra 15 / Side 0 — status: Legal.

Identity & game plan

• Win condition: Galaxy-Eyes / Tachyon Xyz ladder into Number 107, Neo Galaxy-Eyes C107 or Dragluxion, backed by negation; Seventh / Rank-Up-Magic recursion and searcher-driven pressure
• Turn 1 (going first): Open a Level 8 Dragon or Tachyon Cloudragon starter, search through Seventh Ascension or Dragluxion, Xyz into 107 or Dragluxion; hold Dominus Purge and Dominus Spark for opponent activations (Inferred)
• Turn 2 (going second): Use the 7 hand traps (Ash Blossom x2, Infinite Impermanence x2, Maxx C, Droll & Lock Bird, Nibiru) to break the first summon, then follow up through the Xyz ladder (Inferred)
• Recovery: Searchers (13 cards with search text) and Afterglow / Dragluxion recursion rebuild the Xyz ladder after a broken opening (Inferred)
• After siding: No side deck is registered, so there is no post-side plan to evaluate

Why it scores here

The deck reliably opens a Galaxy-Eyes/Tachyon Xyz ladder: 9 archetype-core copies give about a 61% chance of at least one in a 5-card opening hand, and 13 searcher-text cards give about 76% for at least one, both Inferred from the hypergeometric estimates. Its interaction is the strongest part of the system: 22 negation-text and 21 removal-text cards, plus 7 hand traps, let it stand up to a first summon on either turn order. Its Extra Deck offers a high ATK ceiling (Neo Galaxy-Eyes C107 at 4500, Full Armor Photon at 4000, Number 107 and Primal at 3000). The score is held down by the absence of any recorded boards, so combo floor and median are unmeasured and rated low, by a empty side deck that gives no post-side plan, and by low archetype purity (4.3% exact-name) that spreads the main deck across Galaxy-Eyes, Dominus, Seventh, Mulcharmy and Starliege. Popularity was not credited: the 5 of 18 core usage cards present is noted as a weakness, and the score comes from consistency, interaction and closing power on the system, not from averaging card scores.

Dimension scores

How the score was computed

Strategy profile: Midrange. Structural ≈ 57.8, Going First ≈ 60, Going Second ≈ 62, Meta = provisional, Tournament Reliability ≈ 50. Modifiers: Empty side deck (-2); Banlist exposure (-2); Engine conflicts and low archetype purity (-2). Final formula: 0.80*Structural + 0.20*TournamentReliability (Meta provisional); 0.80*57.8 + 0.20*50 = 56.2, then -6 modifiers = 50.2 -> 50

Probability & combo summary

• Opening a starter: P(≥1) ≈ 0.61 · 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

• Dense negation and removal package (22 negation-text, 21 removal-text cards)
• Seven hand traps give going-second answers
• High-ATK Extra Deck ceiling with Number 107, C107 and Dragluxion
• Legal: all restricted cards within copy limits

Weaknesses

• Empty side deck: no post-side adaptation
• Low archetype purity (4.3%); multiple sub-engines compete for slots
• No recorded combo boards, so the floor and median are unknown
• Five of the 18 high-usage archetype cards are present (27.8%)

Critical choke points

• Xyz ladder depends on Level 8 Dragon starters (Tachyon Cloudragon, Primal) being drawn
• Number 107 x2 and Dragluxion x2 are the Extra Deck backbone; loss of both removes most of the finisher count

Recommended changes

Evidence & confidence

• Verified: Legality: Legal, 54 main / 15 extra / 0 side, within OCG size rules; Banlist: 5 Limited 1-of and Ash Blossom Semi-Limited x2, all at legal copy counts; Card text for all resolved cards; Usage stats: 5 of 18 core cards present
• Inferred: Starter access ~61% for core, ~76% for searcher text (hypergeometric); Interaction density and going-second hand trap value; Xyz ladder as primary win condition; Brick risk from situational traps
• Provisional: Meta power (no dated sample); Matchup and format fit (no tournament link); Tournament reliability
• Data gaps: No combos supplied: floor, median and ceiling are text-only inference No tournament link: archetype meta-share and pilot match record absent No win-rate telemetry (going-first/second, matchup, brick/starter rates) Meta power provisional without a dated metagame sample Usage stats conflict with the deck list: Number 38, Number 107, Dragluxion and Full Armor Photon are flagged in_this_deck=false but appear in the cards list Side deck empty, so no post-side evidence
