Legality

Main 56 / Extra 15 / Side 0 — status: Illegal. 3 violation(s).

Identity & game plan

  • Win condition: Xyz pressure from Galaxy-Eyes / Tachyon Xyz monsters (Number 107 and Full Armor Photon Dragon, both in the Extra Deck) backed by hand-trap protection, as far as the list allows; Light and Darkness Dragon fusion and Dragon-recursion lines (Dark End Evaporation Dragon, Light and Darkness Dragonlord)
  • Turn 1 (going first): Open a Tachyon / Galaxy-Eyes starter, then build an Xyz board while holding hand traps for the opponent's first interaction; no combo boards are recorded, so this is inferred from card text
  • Turn 2 (going second): Hold 6-card hand traps (Ash Blossom, Infinite Impermanence, Droll & Lock Bird, Nibiru) to answer the first meaningful opponent play before Xyz conversion
  • Recovery: Recursion from the Graveyard via Xyz Encore, Tachyon Cloudragon and Dragon-tribute lines (Inferred from text)
  • After siding: Not evaluable: the deck runs no Side Deck (side_count 0)

Why it scores here

The list has 13 hand traps and 11 searcher-text cards, so the deck can usually put a live interaction piece in hand, with P(at least one of 11 core copies in a 5-card opening hand) of about 0.68 (Inferred). Its Extra Deck supplies Xyz pressure with 12 Xyz monsters, 2 Fusion monsters and 1 Link monster. No combo boards were recorded, so the ceiling and median scores are text-only inference and are scored low. The score does not come from popularity or from averaging card scores: the deck has no side deck, runs 3 copies of Seventh Tachyon and Ash Blossom above their OCG limits, and includes Catapult Turtle, which is Forbidden. Because the list is illegal, it is capped as a theoretical, structural-only evaluation.

Dimension scores

# Dimension Score Evidence
D1 Engine Accessibility & Consistency 55 P(at least one of 11 core-group copies in a 5-card opening hand) is about 0.68; the two-card bootstrap is Inferred from text and the core sample is small (Inferred)
D2 Opening-Hand Quality & Brick Management 45 13 hand traps and 14 three-of slots raise the risk of dead or redundant hands; no brick rate was measured (Inferred)
D3 Combo Conversion & Ceiling 30 best_line is absent (no parseable boards), so conversion is a text-only read of Xyz and Fusion routes (Inferred)
D4 Combo Floor & Median Output 30 median_power_index is absent; floor cannot be measured from recorded boards (Inferred)
D5 Interruption Resilience & Route Redundancy 55 multiple hand traps and Xyz recursion give some alternate lines, but the recorded starter diversity is unknown (Inferred)
D6 Resource Economy, Recovery & Grind 40 Xyz Encore, Tachyon Cloudragon and Dragon-tribute text suggest partial recovery; no resource data exists (Inferred)
D7 End-Board & Interaction Quality 65 interaction text is dense (18 negation-text and 14 removal-text cards); no board-state measurement exists (Inferred)
D8 Going-Second & Board-Breaking Power 55 interaction is strong against the first play, but Lightning Storm and Harpie's Feather Duster are the only board-breaking tools and are both one-copy or two-copy (Inferred)
D9 Offensive Pressure & Closing Power 50 Xyz boss monsters (Number 107 at 3000 ATK, Full Armor Photon Dragon at 4000 ATK) support closing, but no damage data exists (Inferred)
D10 Main Deck Efficiency & Flexibility 45 56 Main Deck cards with 26 distinct names and 14 three-of slots; 70 of 56 Main copies are off-archetype, so coherence is mixed (Verified composition)
D11 Extra Deck Efficiency & Coverage 60 12 Xyz, 2 Fusion and 1 Link across 15 Extra slots gives a full Extra Deck with reasonable flexibility (Verified composition)
D12 Side Deck Adaptability 20 no Side Deck is present, so post-side adaptability cannot be scored (Verified)
D13 Matchup Coverage & Format Fit 40 no tournament link, meta share, or dated metagame sample exists; Meta Power is provisional (Provisional)
D14 Pilotability & Error Tolerance 40 several multi-step Xyz and hand-trap decisions raise the pilot burden; no pilot data exists (Inferred)

How the score was computed

Strategy profile: Midrange primary, Control secondary (disclosed, not blended numerically). Structural ≈ 46, Going First ≈ 45, Going Second ≈ 42, Meta = provisional, Tournament Reliability ≈ 35. Modifiers: banlist exposure (-12); illegal-deck cap (-14). Final formula: No reliable metagame: 0.80*Structural + 0.20*TournamentReliability = 44, then -12 banlist exposure modifier = 32, then illegal-deck cap to 18 (theoretical, structural-only)

Probability & combo summary

  • Opening a starter: P(≥1) ≈ 0.68 · 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

  • Strong hand-trap density (13) gives early interaction
  • 12 Xyz plus 3-copy Galaxy-Eyes and Tachyon starters give a coherent Extra Deck engine
  • Dense negation and removal text covers multiple turns of interaction

Weaknesses

  • Illegal list: three copy-limit or banlist violations
  • No Side Deck, so no post-side plan
  • Many 3-of slots of narrow starters raise the brick risk
  • No recorded boards, so the combo ceiling and median are unmeasured

Critical choke points

  • Seventh Tachyon and Ash Blossom both need legal copy counts before the list can be played
  • Catapult Turtle is Forbidden in OCG and must be removed
Priority Remove Add Reason
1 Catapult Turtle (1 copy, Forbidden) A legal OCG-playable Main Deck slot Forbidden cards make the list illegal
2 One copy each of Seventh Tachyon and Ash Blossom & Joyous Spring Legal-count replacement slots Reduce Seventh Tachyon to 1 copy (Limited) and Ash Blossom to 2 copies (Semi-Limited)
3 Excess 3-of narrow starters Side Deck (up to 15 cards) The deck has no Side Deck, so post-side adaptability is 0

Evidence & confidence

  • Verified: Legality: Illegal; Catapult Turtle Forbidden, Seventh Tachyon 3 vs 1 and Ash Blossom 3 vs 2; Composition: 56 Main, 15 Extra, 0 Side; 13 hand-trap-tagged cards; Extra Deck breakdown: 12 Xyz, 2 Fusion, 1 Link
  • Inferred: P(at least one core-group copy in a 5-card opening hand) is about 0.68; Interaction density is high based on card text; Recovery lines are based on card text only
  • Provisional: Meta Power and matchup fit: no dated metagame sample
  • Data gaps: No combos supplied: combo floor, median and ceiling are text-only inference No tournament link: archetype meta-share and pilot record are absent No win-rate telemetry exists in YGOVN Meta Power is provisional unless a dated metagame sample is supplied No Side Deck is present, so post-side scores are not measurable
