Legality

Main 55 / Extra 15 / Side 0 — status under the rules at evaluation time: Illegal. 2 violation(s).

Identity & game plan

  • Win condition: Xyz/Link boss plays (Galaxy-Eyes Photon Dragon line, Number 62 / Number C107 / Number 107 variants) that end the turn with a 3000+ ATK board; Galaxy-Eyes Tachyon Primal and Tachyon Cloudragon recursion into a Dragon Xyz
  • Turn 1 (going first): Open a Galaxy/Tachyon starter (Tachyon Transmigration, Galaxy-Eyes Tachyon Primal, Mulcharmy Fuwalos) and Xyz into Galaxy-Eyes Photon Dragon or a Dragon Xyz boss, holding hand traps for the opponent's turn
  • Turn 2 (going second): Use the six-card hand's hand traps (Ash Blossom, Infinite Impermanence, Effect Veiler, Ghost Ogre, Nibiru, Solemn Warning) to break the opponent's first board, then rebuild through Primal and Photon Dragon
  • Recovery: Galaxy-Eyes Tachyon Primal and Tachyon Cloudragon recursion from GY, Galactikuriboh and Photon Jumper Special Summon, plus Dragon Shrine for Dragon monsters
  • After siding: No side deck is registered; no post-side plan can be evaluated

Why it scores here

The deck is Illegal: Ash Blossom & Joyous Spring runs 3 copies against an OCG limit of 2, and Seventh Tachyon runs 2 against a limit of 1, so the normal Final score is capped at 30 and the evaluation is structural-only. Structurally it reliably opens a Galaxy/Tachyon starter (P(at least one of 10 Tachyon/Galaxy starters in a 5-card hand) is about 0.65 on the archetype core group) and has real hand-trap density, with about 82% chance of at least one hand trap in a going-second 6-card hand (Inferred). The main deck converts through a Xyz/Link boss plan whose floor and median output cannot be measured because the export contains no recorded boards, so combo scores are text-only reads (Inferred). Interaction is strong on paper, with 22 negation-text and 14 removal-text cards, but there is no side deck and no post-side evidence. Popularity was not credited: the archetype usage data supports the list being a real, accessible build, not a strong one, and the card scores were not averaged.

Dimension scores

# Dimension Score Evidence
D1 Engine Accessibility & Consistency 62 P(at least one Galaxy/Tachyon starter in a 5-card hand) is about 0.65 on the archetype core group; 3 Tachyon Transmigration and 3 Galaxy-Eyes Tachyon Primal support a multi-starter opening (Inferred)
D2 Opening-Hand Quality & Brick Management 50 13 hand traps and 7 searchers give a functional hand in most draws, but many starters are conditional on a Galaxy or Tachyon board, so bricks are common (Inferred)
D3 Combo Conversion & Ceiling 55 Ceiling reads from text: Photon Dragon, Number 62 and Number C107 can each produce a 3000+ ATK board, but no recorded boards exist to confirm the line (Inferred, text-only)
D4 Combo Floor & Median Output 40 Median output is unmeasured: combos_evidence has zero parseable boards, so the floor is a text-based guess well below the ceiling (Inferred, low confidence)
D5 Interruption Resilience & Route Redundancy 60 Multiple hand traps and recursion (Primal, Cloudragon, Galactikuriboh, Photon Jumper) give more than one line after a single negate (Inferred)
D6 Resource Economy, Recovery & Grind 50 Primal and Cloudragon recursion plus Dragon Shrine and Mulcharmy draw support the grind; resource cost is high on Extra-Deck summons (Inferred)
D7 End-Board & Interaction Quality 70 22 negation-text cards, 13 hand traps, and 14 removal-text cards give broad, layered interaction (Inferred semantic read, plus role-tag counts)
D8 Going-Second & Board-Breaking Power 65 Going-second hand-trap chance is about 0.82 (hypergeometric, 13 copies), and Schwarzschild and Nibiru add board-breaking from the opponent's turn (Inferred)
D9 Offensive Pressure & Closing Power 65 Boss ATK reaches 3000 to 4500 (Photon Dragon, Number C107, Number 62), with 2 Number 107 and Number 38 for Xyz pressure; direct attack text is limited (Inferred)
D10 Main Deck Efficiency & Flexibility 50 55 main cards with 23 tech/role-tagged cards and 3-copy stacks of 10 cards; the deck is already over the copy limit on two cards, which lowers compactness (verified count, Inferred read)
D11 Extra Deck Efficiency & Coverage 55 Extra Deck is full at 15 with 13 distinct cards across Xyz/Link bosses; every Extra slot is a boss or Link and there is no flex slot (Inferred)
D12 Side Deck Adaptability 15 0 side-deck cards are registered, so there is no side-deck plan to score (verified, no post-side data)
D13 Matchup Coverage & Format Fit 50 No tournament link and no dated meta sample exist, so matchup fit is Provisional; the 55% usage share of Photon Emperor and the 55% share of Galaxy Expedition are only context (Provisional)
D14 Pilotability & Error Tolerance 40 Many multi-step Xyz/Link pivots, detach timing, and once-per-turn tracking across 13 distinct Extra cards make the deck demanding to pilot (Inferred)

How the score was computed

Strategy profile: Midrange only; Stun noted as secondary and not blended into the weights. Structural ≈ 54.3, Going First ≈ 52, Going Second ≈ 60, Meta = provisional, Tournament Reliability ≈ 48. Modifiers: banlist exposure (-4); no side deck (-2). Final formula: No reliable metagame: 0.80*Structural + 0.20*TournamentReliability = 0.80*54.3 + 0.20*48 = 53.0; context modifiers -6 gives 47.0; Illegal legality cap applied, final = 30 (structural-only, theoretical)

Probability & combo summary

  • Opening a starter: P(≥1) ≈ 0.65 · 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

  • Broad layered interaction: 13 hand traps, 22 negation-text cards, 14 removal-text cards
  • Multiple Galaxy/Tachyon starters with recursion (Primal, Cloudragon, Galactikuriboh)
  • Strong Xyz/Link boss top end (3000 to 4500 ATK)

Weaknesses

  • Illegal list: two cards over the OCG copy limit
  • No side deck
  • High tech density (23 tech-tagged cards) lowers compactness
  • Heavy Extra-Deck pivot requirements for a Galaxy/Tachyon board

Critical choke points

  • Galaxy/Tachyon starter access on turn 1 (about 0.65 for at least one in a 5-card hand)
  • Single Dragon Xyz on the field needed for Primal and Photon Dragon lines
Priority Remove Add Reason
1 1 Ash Blossom & Joyous Spring A legal, non-restricted replacement (e.g. Galaxy Expedition, which appears in the archetype usage data at 51%) Brings the deck within the OCG copy limit of 2 for Ash Blossom; required to make the list legal
2 1 Seventh Tachyon A legal replacement card Seventh Tachyon is Limited (1 copy); the deck runs 2
3 Weak tech cards (e.g. Dragon Shrine x2 or 1 Lightning Storm) A side deck of 3 to 5 cards A side deck is needed for a post-side plan (D12 is currently 15)

Evidence & confidence

  • Verified: Main 55, Extra 15, Side 0 (OCG size rules 40-60 / 0-15 / 0-15); Ash Blossom & Joyous Spring 3 copies vs legal 2; Seventh Tachyon 2 copies vs legal 1; Limited and Semi-Limited status for listed cards; Archetype usage: Number 38 87%, Number 90 79%, Afterglow 70%, Galaxy-Eyes Full Armor 70% (usage stats)
  • Inferred: Starter consistency (about 0.65 on the archetype core, hypergeometric); Hand-trap chance on going second (about 0.82); Interaction breadth from card text (22 negation, 14 removal); Boss ceiling and closing power from printed ATK
  • Provisional: Meta Power (no dated meta sample); Matchup and format fit
  • Data gaps: Usage evidence is inconsistent with the deck list: in_this_deck is false for Number 38, Number 90, Number 107, Galaxy-Eyes Full Armor, and Number C62, which are all present in cards[]. Likely cause: the usage match misses Extra Deck cards. core_present_pct 26.7 is therefore wrong; by the card list 11 of 15 core cards are present (about 73%). Re-run the usage join on the full card list. 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 no side deck registered, so no post-side evidence deck title is null
