Legality
Main 43 / Extra 15 / Side 0 — status under the rules at evaluation time: Illegal. 1 violation(s).
Identity & game plan
- Win condition: Blue-Eyes and Dragon-type boards from Blue-Eyes Ultimate Spirit Dragon, Neo Blue-Eyes Ultimate Dragon, Blue-Eyes Tyrant Dragon and Cosmic Blazar Dragon (Inferred from card text; no recorded boards); Hand-trap-supported Dragon Synchro and Link summons (Inferred)
- Turn 1 (going first): Normal Summon a Level 1 Tuner or Neo Kaiser Sea Horse, search or summon into a Blue-Eyes White Dragon engine, and keep Effect Veiler, Ash Blossom or Ghost Ogre up as protection (Inferred)
- Turn 2 (going second): Use the hand traps (Effect Veiler, Ash Blossom, Droll & Lock Bird, Infinite Impermanence, Solemn Strike, Ghost Ogre) to answer the opponent's first board, then rebuild through Crimson Dragon or Blue-Eyes Spirit Dragon (Inferred)
- Recovery: Recover through the Graveyard Tuners and Blue-Eyes Spirit Dragon effects, plus Mausoleum of White and Spirit with Eyes of Blue as searchers (Inferred)
- After siding: Not applicable: the deck runs no Side Deck (0 cards)
Why it scores here
The deck is Illegal because it runs 3 copies of Ash Blossom & Joyous Spring against an OCG limit of 2, so it is scored as theoretical and structural only and capped at 30. Its searcher and Tuner density gives a reasonable chance of a live starter in an opening hand (about 0.71 for at least one searcher-text card in 5 cards, Inferred), but the list mixes at least eight sub-archetypes with no shared engine (Blue-Eyes, with Eyes of Blue, Bystial, Archfiend, Hieratic, Stardust, Solemn, Greed), so consistency is weaker than its starter count suggests. Its 15 hand-trap-tagged cards and Extra Deck of Dragon Synchro and Link monsters give real interaction and a strong late-board ceiling, which the structural score credits, but there are no recorded boards to measure a median. The deck has no Side Deck and no meta or tournament data, so Meta Power stays null and Tournament Reliability is held down. Popularity did not earn points: the Synchron usage stats show Droll & Lock Bird at 56% inclusion and the Mulcharmy core missing, which confirms the list is real rather than strong. No card scores were averaged; the score comes from the deck system.
Dimension scores
| # | Dimension | Score | Evidence |
|---|---|---|---|
| D1 | Engine Accessibility & Consistency | 58 | P(at least one searcher-text card in opening 5) about 0.71; 3-copy Tuner starters but the Mulcharmy core is absent (Inferred) |
| D2 | Opening-Hand Quality & Brick Management | 45 | 15 hand-trap-tagged cards and 10 three-copy slots in a 43-card Main; conflicting engines raise dead-card risk (Inferred) |
| D3 | Combo Conversion & Ceiling | 50 | No parseable recorded boards; ceiling comes from Blue-Eyes Ultimate Spirit and Neo Blue-Eyes text only (Inferred) |
| D4 | Combo Floor & Median Output | 42 | No combos supplied, so median output cannot be measured; floor is text-only (Inferred) |
| D5 | Interruption Resilience & Route Redundancy | 55 | Several independent Tuner and hand-trap lines interrupt play, but the Dragon engine is single-threaded through Blue-Eyes White Dragon (Inferred) |
| D6 | Resource Economy, Recovery & Grind | 45 | Searchers and Graveyard recursion exist, but hand-trap spend and Pot of Prosperity Extra Deck banishment cost resources (Inferred) |
| D7 | End-Board & Interaction Quality | 62 | 15 hand-trap-tagged cards, Solemn Strike, Infinite Impermanence, Lightning Storm and Cosmic Blazar negation text (Inferred semantic read from card text) |
| D8 | Going-Second & Board-Breaking Power | 58 | Hand traps and Droll & Lock Bird answer the opponent's first board on the draw; no board-breaker count is verified (Inferred) |
| D9 | Offensive Pressure & Closing Power | 62 | Extra Deck ATK reaches 3400 to 4500 (Blue-Eyes Ultimate Spirit 3500, Neo Blue-Eyes 4500, Cosmic Blazar 4000) (Verified stat) |
| D10 | Main Deck Efficiency & Flexibility | 40 | 43 Main cards over 21 distinct names with 3 tech slots and off-archetype density; 43 is legal size but not compact (Verified count, Inferred effect) |
| D11 | Extra Deck Efficiency & Coverage | 62 | 15 Extra Deck slots across Synchro, Link and Fusion, with two Blue-Eyes Fusion and Synchro options (Verified count, Inferred use) |
| D12 | Side Deck Adaptability | 15 | Side Deck is empty, so there is no post-side plan (Verified: Side Deck size 0) |
| D13 | Matchup Coverage & Format Fit | 40 | No tournament link and no dated meta sample; archetype usage alone is not a format-fit read (Provisional) |
| D14 | Pilotability & Error Tolerance | 35 | Multiple engines and up to 6 hand-trap decision points per turn make the deck hard to pilot consistently (Inferred) |
How the score was computed
Strategy profile: Midrange. Structural ≈ 49.7, Going First ≈ 46, Going Second ≈ 54, Meta = provisional, Tournament Reliability ≈ 42. Modifiers: Illegal copy-limit cap (-18). Final formula: 0.80*Structural + 0.20*TournamentReliability (Meta provisional) = 48.0, then illegal-deck cap modifier -18 = 30
Probability & combo summary
- Opening a starter: P(≥1) ≈ 0.71 · 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 hand-trap and negation suite covering both going-first and going-second turns
- Strong Extra Deck closing power (Blue-Eyes Ultimate Spirit, Neo Blue-Eyes, Cosmic Blazar, Stardust Sifr)
- Searcher density gives a high chance of a live starter in an opening hand
Weaknesses
- Illegal: Ash Blossom & Joyous Spring over the OCG copy limit
- No Side Deck, so no post-side adaptation
- Multiple unrelated sub-archetypes with no shared engine; the archetype core is missing
Critical choke points
- Blue-Eyes White Dragon is the single engine entry for most Extra Deck lines
- Ash Blossom over-limit: removing one copy changes the legal draw odds
Recommended changes
| Priority | Remove | Add | Reason |
|---|---|---|---|
| 1 | One copy of Ash Blossom & Joyous Spring | A legal single-copy card or a second copy of a non-limited hand trap | Makes the list legal so it can receive a normal Final Contextual score |
| 2 | Off-archetype tech and Pot of Prosperity | A Side Deck of 15 cards | Adds post-side adaptation (D12 at 15 is the weakest dimension) |
Evidence & confidence
- Verified: Main 43, Extra 15, Side 0 are within OCG size rules; Ash Blossom & Joyous Spring run 3 copies, legal 2 (Semi-Limited); Blue-Eyes Ultimate Spirit ATK 3500, Neo Blue-Eyes ATK 4500, Cosmic Blazar ATK 4000
- Observed: Synchron usage: Droll & Lock Bird inclusion 56.3%, Mulcharmy Fuwalos inclusion 60.6% (missing from this list)
- Inferred: P(at least one searcher-text card in 5 cards) about 0.71; Engine coherence reduced by 11 sub-archetypes; Interaction density from hand-trap and negation text
- Provisional: Meta Power (no dated metagame sample); Matchup fit (D13)
- Data gaps: No combos supplied, so 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; going-first, going-second and brick rates are Inferred Meta Power is Provisional unless a dated metagame sample is supplied No Side Deck
