Legality
Main 40 / Extra 15 / Side 0 — status under the rules at evaluation time: Illegal. 2 violation(s).
Identity & game plan
- Win condition: Extra Deck boss pressure (Poseidra Abyss, Abysstrite, Mermail Abyssgaios, Azure Ocean Dragon Lord) enabled by Atlantean and Mermail searchers and the Atlantis field spell; Negation and hand-trap interaction (Ash Blossom, Infinite Impermanence, Maxx C, Dominus Impulse, Daedalus Maelstrom) that protects the board while the boss is set up
- Turn 1 (going first): Open Neptabyss or Mermail Shadow Squad, search an Atlantean or Atlantis card, and summon toward a Level 7 Xyz or Link boss (Inferred)
- Turn 2 (going second): Hold Ash Blossom, Dominus Impulse, Impermanence and Maxx C to answer the opponent's summon, then rebuild through GY recursion (Inferred)
- Recovery: Recover through GY-activated effects (Mermail Abysspike, Atlantean Heavy Infantry, Mediclius-style recursion) and searchers that refill the hand (Inferred)
- After siding: None: the deck runs 0 side cards and the list is Illegal, so no post-side plan can be verified
Why it scores here
The deck reliably opens a functional Atlantean starter: the archetype-core group has about 98% chance of at least one card in a 5-card opening hand, and three-copy searchers such as Neptabyss and Mermail Shadow Squad give a 34% direct starter chance on the play (Inferred). Interaction is the strongest part of the system: six hand traps plus removal text give 65 on endboard interaction quality, and this is what carries the score rather than any single card. Combo conversion and floor are unscored in practice because the export has no recorded boards, so D3 and D4 are inferred from card text and stay low-confidence. Popularity did not earn points: the archetype core is widely used, but only 21.8% of the main deck is exact-name Atlantean, and the 15-card Extra Deck spreads across several sub-archetypes, which lowers coherence. The list is Illegal (two Forbidden Bahamut Shark copies and one Forbidden Barrier Statue), so the score is capped at 30 as a theoretical, structural-only read; scores were not produced by averaging card power.
Dimension scores
| # | Dimension | Score | Evidence |
|---|---|---|---|
| D1 | Engine Accessibility & Consistency | 55 | P(>=1 archetype-core card in 5-card hand) ~0.98; P(>=1 Neptabyss or Mermail Shadow Squad in 5) ~0.34 (Inferred) |
| D2 | Opening-Hand Quality & Brick Management | 45 | Only 21.8% exact-name Atlantean purity and 43 off-archetype copies raise brick and conflict risk; no side deck to fix hands (Inferred) |
| D3 | Combo Conversion & Ceiling | 55 | No recorded boards; ceiling inferred from Extra Deck boss density and Atlantis field spell routing (Inferred) |
| D4 | Combo Floor & Median Output | 40 | No combo data, so median output cannot be measured and is held at a conservative value (Inferred) |
| D5 | Interruption Resilience & Route Redundancy | 58 | Several searchers and GY-revival routes give alternate lines after one disruption; no measured data (Inferred) |
| D6 | Resource Economy, Recovery & Grind | 60 | 14 searcher-text cards and GY-activated recursion sustain the grind; spend and float unmeasured (Inferred) |
| D7 | End-Board & Interaction Quality | 65 | Six hand traps and about 10 negation-text cards form layered interaction (Verified card text, Inferred quality) |
| D8 | Going-Second & Board-Breaking Power | 55 | Going-second hand-trap coverage is about 0.65 for at least one in a 6-card hand, but Barrier Statue is Forbidden and cannot be run (Inferred) |
| D9 | Offensive Pressure & Closing Power | 55 | Level 7+ Xyz and Link bosses (Poseidra Abyss 3000 ATK, Azure Ocean Dragon Lord 2900 ATK) give closing power; no endboard data (Inferred) |
| D10 | Main Deck Efficiency & Flexibility | 50 | 40 main with 25 distinct cards and 15 singleton slots; compactness is adequate but purity is low (Verified composition) |
| D11 | Extra Deck Efficiency & Coverage | 55 | 15 Extra Deck cards across Xyz, Link and Synchro with many dependencies on Atlantean/Mermail fill (Verified composition, Inferred use) |
| D12 | Side Deck Adaptability | 25 | Side deck is 0 cards; no post-side plan exists (Verified) |
| D13 | Matchup Coverage & Format Fit | 40 | No tournament link and no dated meta sample, so matchup fit is provisional (Provisional) |
| D14 | Pilotability & Error Tolerance | 40 | Multiple sub-archetypes, Extra Deck material routes and a high decision count make pilotage demanding (Inferred) |
How the score was computed
Strategy profile: Midrange. Structural ≈ 52, Going First ≈ 50, Going Second ≈ 52, Meta = provisional, Tournament Reliability ≈ 45. Modifiers: banlist exposure (Forbidden cards in format) (-12); illegal-list cap (-8). Final formula: No reliable metagame: 0.80*Structural(52.3) + 0.20*TournamentReliability(45) = 50.8; banlist-exposure modifier -12 gives 38.8; Illegal cap sets final to 30 (theoretical / structural-only)
Probability & combo summary
- Opening a starter: P(≥1) ≈ 0.98 · 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 (Ash Blossom, Impermanence, Maxx C, Dominus Impulse, Daedalus Maelstrom)
- Redundant searchers (Neptabyss, Mermail Shadow Squad, Atlantean Dragoons, Mermail Abysspike) for starter access
- Strong Extra Deck bosses across Xyz, Link and Synchro
Weaknesses
- Illegal list: two Forbidden Bahamut Shark and one Forbidden Barrier Statue
- Low archetype purity (21.8%) with many off-archetype cards
- No side deck, so no post-side adaptability
- Combo output unmeasured (no recorded boards)
Critical choke points
- Starter access depends on a single Atlantean or Mermail searcher in hand (about 34% on the play per 3-copy card)
- Bahamut Shark and Barrier Statue removal would break any line that depends on them
Recommended changes
| Priority | Remove | Add | Reason |
|---|---|---|---|
| 1 | Bahamut Shark x2 and Barrier Statue of the Torrent x1 | Legal Atlantean or Mermail Extra Deck or main-deck replacements (for example, a legal Level 7 WATER Xyz or Link) | Restores legality; the current list cannot earn a normal Final score |
| 2 | Off-archetype singletons (generic tech cards) | Additional Atlantean or Mermail searchers or staples | Raises archetype purity and starter consistency (Inferred) |
| 3 | None | A 10-15 card side deck | A side deck is needed for best-of-3 adaptability (D12 currently 25) |
Evidence & confidence
- Verified: Illegal status: Bahamut Shark x2 (legal 0) and Barrier Statue x1 (legal 0) are Forbidden in OCG; Main 40, Extra 15, Side 0 within OCG size rules; Archetype purity 21.8% and 43 off-archetype copies
- Inferred: Starter access about 0.98 for the archetype-core group and about 0.34 for 3-copy searchers on the play; Interaction density is high based on text roles; Going-second plan through hand traps (about 0.65 chance of one in hand 6)
- Provisional: Meta Power (no dated metagame sample); Matchup fit (no tournament link)
- Data gaps: No combos supplied; combo floor, median and ceiling are text-only inference No tournament link; archetype meta-share and per-pilot record are absent No win-rate telemetry exists for this deck (going-first/second, matchup, brick and starter rates) Meta Power is Provisional unless a dated metagame sample is supplied No side deck supplied
