Legality

Main 55 / Extra 15 / Side 0 — status under the rules at evaluation time: Illegal. 3 violation(s).

Identity & game plan

Win condition: Dragon Xyz boss pressure (Number 62, Number C107, Dragluxion, Cipher Blade) reached through Galaxy-Eyes and Tachyon material routes; Galaxy-Eyes Afterglow and Tachyon Cloudragon special-summon lines feeding Xyz monsters
Turn 1 (going first): Open on hand-trap-protected starters (Ash Blossom, Droll, Solemn) and Xyz set-up from Galaxy-Eyes or Tachyon monsters; Inferred, no combos recorded
Turn 2 (going second): Hold Ash Blossom, Droll & Lock Bird and Solemn to disrupt the opponent's starter, then extend with Xyz summons from the Extra Deck
Recovery: Galaxy-Eyes material transfer and Seventh Ascension / Dragon's Light and Darkness searches to rebuild Xyz boards; Inferred from card text
After siding: Not evaluable: Side Deck size is 0, so no post-side plan exists in the export

Why it scores here

The deck is scored on its system, not as an average of card scores. Its interaction suite (three Ash Blossom, Droll & Lock Bird, Solemn, Evenly Matched, Tachyon Transmigration) and its Extra Deck of high-ATK Xyz boss monsters are the strongest parts of the build. Its engine is fragmented across at least five archetype families (Galaxy-Eyes, Mulcharmy, Seventh, Egyptian God, Starliege) with only 2 exact-name Tachyon copies, so the probability that the core engine is live on turn 1 or 2 is modest (about 0.65 for at least one archetype-core card in a 5-card opening, Inferred). The list is Illegal in OCG: Seventh Tachyon and Ash Blossom exceed their limits and Catapult Turtle is Forbidden, so the score is capped and labelled theoretical. No combos, guides or tournament data exist, so floor, median and ceiling are not measured. Popularity or archetype share did not earn points.

Dimension scores

#	Dimension	Score	Evidence
D1	Engine Accessibility & Consistency	40	P(at least one archetype-core card in a 5-card opening) about 0.65 across 10 core copies; engine spread over several sub-archetypes (Inferred)
D2	Opening-Hand Quality & Brick Management	42	Seven hand traps and about 14 three-of cards with conflicting Normal Summon and archetype needs raise brick risk; no brick rate measured (Inferred)
D3	Combo Conversion & Ceiling	45	Ceiling reads from card text only (Galaxy-Eyes Tachyon, Number C107 and Dragluxion lines) with no recorded boards (Inferred)
D4	Combo Floor & Median Output	35	No combo boards or power distribution exist, so the median is unmeasured and conservatively low (Inferred)
D5	Interruption Resilience & Route Redundancy	55	Multiple independent negates (Ash, Droll, Solemn, Evenly Matched, Transmigration) give some route redundancy after disruption (Inferred)
D6	Resource Economy, Recovery & Grind	50	Seventh Ascension and Dragon's Light and Darkness search, and Xyz material transfer recovers boards; no resource data (Inferred)
D7	End-Board & Interaction Quality	72	Interaction density is high: 18 negation-text and 18 removal-text cards, including Solemn and hand-trap negates (Inferred from text, Verified flags)
D8	Going-Second & Board-Breaking Power	62	Hand traps Ash and Droll are strong in the going-second 6-card hand; going-second split not measured (Inferred)
D9	Offensive Pressure & Closing Power	72	Extra Deck carries 4000 ATK and 4500 ATK Xyz boss monsters with direct-attack and battle-phase text; closing power is strong (Verified stats)
D10	Main Deck Efficiency & Flexibility	45	Off-archetype purity is 2.9% exact-name, with 68 off-archetype copies and generic staples diluting the engine (Verified composition)
D11	Extra Deck Efficiency & Coverage	60	Extra Deck is full at 15 with 13 distinct Xyz and Link cards, giving coverage across boss monsters (Verified composition)
D12	Side Deck Adaptability	20	Side deck is empty (Side Deck size 0), so there is no post-side adaptation to score (Verified)
D13	Matchup Coverage & Format Fit	40	No archetype meta-share or tournament link exists, so format fit is Provisional and rated conservatively (Provisional)
D14	Pilotability & Error Tolerance	40	Multi-step Xyz material chains and tuner/hand-trap timing need precise sequencing, giving a moderate pilotability burden (Inferred)

How the score was computed

Strategy profile: Midrange. Structural ≈ 49, Going First ≈ 45, Going Second ≈ 58, Meta = provisional, Tournament Reliability ≈ 40. Modifiers: banlist exposure (-6); forbidden card (-2); engine conflicts (-4); illegal cap (-13). Final formula: 0.80*Structural + 0.20*TournamentReliability (Meta provisional) = 47 before modifiers (-12) = 35; capped at 25 because the list is Illegal (theoretical/structural only)

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

Strong interaction density: negates and removal across hand traps, Solemn and Evenly Matched
High-ATK Extra Deck boss monsters (Number C107 4500, Number 62 4000) with battle-phase text
Full Extra Deck with 14 Xyz and 1 Link giving coverage

Weaknesses

Illegal in OCG: copy limits exceeded for Seventh Tachyon and Ash Blossom, and Forbidden Catapult Turtle is run
Engine split across five sub-archetypes, with 2.9% exact-name Tachyon purity
No side deck, so no post-side adaptation

Critical choke points

Archetype-core starter absent from the opening hand (about 35% of 5-card hands, Inferred)
Forbidden and over-limit cards must be removed before the list is playable

Recommended changes

Priority	Remove	Add	Reason
1	Catapult Turtle (1) and the excess Seventh Tachyon and Ash Blossom copies	Legal-count replacements (for example one Seventh Tachyon and two Ash Blossom in place of three)	The list is Illegal; no normal score applies until it is legal
2	Off-archetype generic staples that lack an engine role	Additional Galaxy-Eyes or Tachyon core cards	Raises archetype purity and the starter probability in opening hands
3	None (side deck is empty)	A 15-card side deck of hand traps and anti-Xyz tech	Enables post-side adaptation, currently unscored (D12 = 20)

Evidence & confidence

Verified: Legality: 55 main, 15 extra, 0 side; over-limit copies of Seventh Tachyon and Ash Blossom; Catapult Turtle Forbidden; Card text and stats of the 14 Xyz, Link and hand-trap cards in the evidence; Exact-name archetype purity 2.9% (2 of 70 main copies)
Inferred: Starter and archetype-core probabilities from hypergeometric draws; Interaction density and going-second value from card text; Brick and recovery risk from composition
Provisional: Matchup and format fit (D13), no meta sample or tournament link; Tournament reliability
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 telemetry: going-first and going-second splits, matchup and brick rates are Inferred or Unknown no side deck (Side Deck size 0): post-side plan unscoreable Meta Power is Provisional unless a dated metagame sample is supplied
