Legality
Main 51 / Extra 15 / Side 0 — status under the rules at evaluation time: Illegal. 1 violation(s).
Identity & game plan
- Win condition: Atlantis/Umi and Daedalus Link/Synchro/Xyz boards (Poseidra, Levia-Dragon, Azure Ocean Dragon Lord, Icejade Gymir Aegirine) overwhelming the opponent, assuming the Forbidden Bahamut Shark slots are removed; Mulcharmy card-advantage stall into the Extra Deck boss
- Turn 1 (going first): Open a WATER starter (Neptabyss / Warchief / Mulcharmy Purulia), search Atlantis or Umi support, and build toward Atlantis-field and Umi-based Extra Deck summons; hold Solemn Strike or Ash Blossom for the first opposing summon
- Turn 2 (going second): Use hand traps (Ash Blossom, Droll & Lock Bird, Maxx "C", Infinite Impermanence) and Dominus Impulse / Solemn Strike to blank the opponent's first board, then convert with Mulcharmy draw effects and a Link or Synchro boss
- Recovery: Mulcharmy Fuwalos and Purulia draw effects plus GY-triggered Atlantean searches (Atlantean Dragoons, Monster Arms of Atlantis) rebuild card count after interaction trades
- After siding: Not evaluable: the deck carries no Side Deck (Side Deck size 0), so no post-side plan exists
Why it scores here
The deck's structural read is built from consistency, interaction density and closing power on the system, not from averaging card scores. Its 19-copy archetype core gives about a 91% chance of at least one core card in a going-first opening hand (Inferred), and 16 searcher-text cards support a plausible T1 starter line. Its interaction suite (Solemn Strike x3, Ash Blossom x2, Dominus Impulse x2, Droll & Lock Bird, Maxx "C", Infinite Impermanence, Harpie's Feather Duster, Daedalus Maelstrom) gives it real going-second and end-board value. Closing power comes from several 2600 to 3000 ATK Link, Synchro and Xyz bosses. Popularity was not credited: the archetype usage stats only confirm the core cards are real and accessible. Points are reduced for the Forbidden Bahamut Shark x2, which makes the list illegal and caps the score; the 12% exact-name purity, the missing Side Deck, and the absence of recorded boards that could ground a combo ceiling.
Dimension scores
| # | Dimension | Score | Evidence |
|---|---|---|---|
| D1 | Engine Accessibility & Consistency | 62 | P(>=1 archetype-core card in 5-card hand) ≈ 0.91 over 19 core copies; exact-name purity only 12%, spread across ~20 sub-archetypes (Inferred) |
| D2 | Opening-Hand Quality & Brick Management | 55 | 7 hand traps and 16 searchers give hand functionality, but 58 off-archetype copies and many single-copy tech cards raise brick and dead-card risk (Inferred) |
| D3 | Combo Conversion & Ceiling | 50 | No parseable boards; ceiling is text-only read of Atlantis/Umi field, Daedalus Link and Neptabyss chains (Inferred) |
| D4 | Combo Floor & Median Output | 40 | No recorded combos, so the median is unmeasured and only structurally estimated (Provisional) |
| D5 | Interruption Resilience & Route Redundancy | 55 | Multiple independent starters and recursion from GY, but interruption depends on hand traps and a single Atlantis field (Inferred) |
| D6 | Resource Economy, Recovery & Grind | 60 | Searcher-text density and GY recursion (Mulcharmy, Warchief, Dragoons) regenerate resources; Pot of Sloth adds draw (Inferred) |
| D7 | End-Board & Interaction Quality | 72 | Solemn x3, Ash x2, Dominus x2, Infinite Impermanence, Daedalus Maelstrom, Droll and Duster give layered interaction; negation and removal text confirmed (Verified text, Inferred quality) |
| D8 | Going-Second & Board-Breaking Power | 62 | Going-second split not measured; hand traps and Maxx "C" suit a going-second plan, but no board-breaker beyond Duster (Inferred) |
| D9 | Offensive Pressure & Closing Power | 68 | Bosses at 2600 to 3000 ATK (Azure Ocean Dragon Lord 2900, Poseidra Abyss 3000, Icejade 3000) give closing power (Verified stats, Inferred conversion) |
| D10 | Main Deck Efficiency & Flexibility | 45 | 51 Main cards with 35 distinct cards and 58 off-archetype copies; compactness is weak, with tech slots and sub-archetype mixing (Inferred) |
| D11 | Extra Deck Efficiency & Coverage | 55 | 15 Extra slots hold 12 distinct cards, but 2 slots are Forbidden Bahamut Shark, which is not playable (Verified legality) |
| D12 | Side Deck Adaptability | 15 | No Side Deck at all (Side Deck size 0), so no post-side adaptability exists (Verified) |
| D13 | Matchup Coverage & Format Fit | 50 | No tournament link or meta sample; archetype usage is context only (Provisional) |
| D14 | Pilotability & Error Tolerance | 45 | Multiple interaction timing decisions and a 3-chain Atlantis/Umi sequence raise decision load (Inferred) |
How the score was computed
Strategy profile: Midrange. Structural ≈ 55, Going First ≈ 58, Going Second ≈ 60, Meta = provisional, Tournament Reliability ≈ 50. Modifiers: banlist exposure (-8); engine conflicts (-2); no Side Deck (-2). Final formula: No reliable metagame: 0.80*Structural + 0.20*TournamentReliability + ContextModifiers = 0.80*55 + 0.20*50 - 12 = 42, then Illegal cap applied to 35 (theoretical/structural-only; Meta provisional)
Probability & combo summary
- Opening a starter: P(≥1) ≈ 0.27 · key two-card combo ≈ — · full-brick estimate ≈ 0.09 (all Inferred)
- Combo output: best PowerIndex —, median —, board-per-starter —
- Turn order: 0 going-first lines vs 0 going-second lines
Strengths
- Layered interaction suite: 14 negation-text cards and 13 removal-text cards
- Core archetype density (19 copies) gives high starter access
- Multiple 2600 to 3000 ATK end-board options across Link, Synchro and Xyz
Weaknesses
- Illegal: 2 copies of Forbidden Bahamut Shark
- No Side Deck
- Low purity (12%) and heavy sub-archetype mixing
- No recorded combos or meta data
Critical choke points
- Bahamut Shark must be removed before the list is playable; the Extra slots it occupies are otherwise unfilled
- Single Atlantis field card gates most Umi-based summons
Recommended changes
| Priority | Remove | Add | Reason |
|---|---|---|---|
| 1 | Bahamut Shark x2 | Two legal Extra Deck boss options (e.g. Poseidra Abyss already run; add a second Atlantean or Mermail Xyz/Synchro boss) | Clears the copy-limit violation so the deck can be scored as a normal legal list |
| 2 | Two single-copy tech cards (e.g. Harpie's Feather Duster, Appointer of the Red Lotus) | A Side Deck of 10 to 15 cards covering the deck's weakness to backrow and boss-level removal | Adds post-side adaptability (D12) and a best-of-3 plan |
| 3 | Off-archetype sub-theme cards (e.g. Click & Echo, Hey Space Trunade!) | Atlantis or Umi support already in the deck | Raises archetype purity and reduces engine conflicts |
Evidence & confidence
- Verified: Bahamut Shark is Forbidden and run at 2 copies (legal copies 0); Main 51 / Extra 15 / Side 0 size counts; Card text and stats for all 51 Main and 15 Extra cards; Usage stats: core cards present 12 of 20 (60%)
- Observed: Usage stats show the archetype core is real and accessible (inclusion % by card)
- Inferred: Starter access and brick estimates from hypergeometric probabilities; Interaction quality from text-role hints; Going-first and going-second estimates
- Provisional: Meta Power (null); Matchup fit (D13); Post-side value (D12 note)
- Data gaps: 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 (going-first/second, matchup, brick and OTK rates) No Side Deck, so best-of-3 adaptability cannot be measured Meta Power is Provisional unless a dated metagame sample is supplied
