Main 40 / Extra 15 / Side 0 — status: Illegal. 2 violation(s).
Identity & game plan
- Win condition: Synchro/Xyz board with negation and removal; Beatdown with high-ATK monsters (Poseidra, Mermail bosses)
- Turn 1 (going first): Open with Atlantean/Mermail starters to establish Level 7 monsters, Synchro into Trishula or Adamancipator Risen-Dragite for disruption, protect with end-board negation
- Turn 2 (going second): Use hand traps (Ash, Nibiru, Droll & Lock Bird) to disrupt opponent's setup, then break board with Forbidden Droplet or removal effects
- Recovery: Graveyard recursion via Mermail searchers and Poseidra effect; resource recovery via Abyss-steam draw effect
- After siding: No side deck available; theoretical post-side plan would adjust hand-trap and tech ratios
Why it scores here
This deck is illegal in OCG format and cannot receive a normal Final Contextual score. Two forbidden cards (Maxx C and Bahamut Shark) are present, making evaluation theoretical only. The list runs only 40% of core Deep Sea cards per usage statistics, heavily splashing Atlantean/Mermail instead. Without combo evidence, legal status resolution, or a valid side deck, scoring is impossible.
Dimension scores
| # | Dimension | Score | Evidence |
|---|---|---|---|
| D1 | Engine Accessibility & Consistency | 0 | Archetype core P(>=1 hand 5) ≈ 0.97 but deck is illegal and heavily off-core (40% of 25 expected cards missing); cannot score (Verified legality violation) |
| D2 | Opening-Hand Quality & Brick Management | 0 | 19 archetype-core copies present, but with Maxx C and Bahamut Shark both forbidden and running Moulinglacia (requires 5 WATER in GY condition), opening hands risk bricking on unmet conditions (Inferred / Illegal) |
| D3 | Combo Conversion & Ceiling | 0 | No combo evidence supplied; text-only read suggests Trishula/Adamancipator boards with 1-2 negations as ceiling, but unverified without recorded lines (Inferred) |
| D4 | Combo Floor & Median Output | 0 | Median output unknown; starter diversity (Neptabyss, Abyssteus, Icejade Ran) could support 2-3 synchro summons, but no observed data (Inferred / Data Gap) |
| D5 | Interruption Resilience & Route Redundancy | 0 | Multiple starter lines and recursion via Mermail effects suggest moderate redundancy, but Moulinglacia as a one-of tech payoff is fragile; only ~2 independent routes without disruption (Inferred) |
| D6 | Resource Economy, Recovery & Grind | 0 | Abyss-steam draw effect and Mermail searchers provide some resource refill; Poseidra recovery effect available; grind potential moderate but unverified (Inferred) |
| D7 | End-Board & Interaction Quality | 0 | End-board interaction: Trishula negates, Adamancipator disruption, Mermail Abyssgaios attack negation layer; ~2-3 distinct disruptions inferred, but board detail unknown (Inferred) |
| D8 | Going-Second & Board-Breaking Power | 0 | Forbidden Droplet and hand-trap suite (Ash x2, Nibiru x1, Droll x1) present for going-second; removal coverage moderate; effective board-break rate unverified (Inferred) |
| D9 | Offensive Pressure & Closing Power | 0 | Poseidra 2800 ATK, Mermail bosses 1700-2100 ATK; Atlantean Dragoons direct attack support on low-level monsters; closing power modest without lethal guarantees (Inferred from card text) |
| D10 | Main Deck Efficiency & Flexibility | 0 | 40-card main with 26 distinct cards; 5 hand-traps + 2 traps + 7 spells + 26 monsters = moderate efficiency; many tech one-ofs (Eria, Moulinglacia, Mermail Abysspike) reduce compactness (Observed) |
| D11 | Extra Deck Efficiency & Coverage | 0 | 15-card Extra Deck: 6 Xyz, 6 Synchro, 3 Link; coverage broad but many slots feel flex (Lancea, Swordsoul Chengying, Marincess Coral); Extra Deck efficiency moderate (Observed) |
| D12 | Side Deck Adaptability | 0 | Side deck absent (0 cards); no post-side adaptation possible; cannot adjust for matchups (Verified constraint) |
| D13 | Matchup Coverage & Format Fit | 0 | Archetype meta-share unavailable; Deep Sea is niche; deck runs only 40% core, heavy Atlantean/Mermail splice; format fit unknown; meta power provisional (Provisional) |
| D14 | Pilotability & Error Tolerance | 0 | Combo complexity moderate (3-4 step lines into Synchro); decision density low for a combo deck; error tolerance likely moderate, but pilotability unverified without examples (Inferred) |
How the score was computed
Strategy profile: None applied. Structural ≈ —, Going First ≈ —, Going Second ≈ —, Meta = provisional, Tournament Reliability ≈ —. Modifiers: none. Final formula: Illegal deck — scoring suppressed. Two forbidden cards present: Maxx C (Forbidden), Bahamut Shark (Forbidden).
Probability & combo summary
- Opening a starter: P(≥1) ≈ 0.97 · key two-card combo ≈ — · full-brick estimate ≈ 0.03 (all Inferred)
- Combo output: best PowerIndex —, median —, board-per-starter —
- Turn order: 0 going-first lines vs 0 going-second lines
Strengths
- Broad Atlantean/Mermail searcher suite enables consistent access to play-starters.
- Multiple Synchro payoffs (Trishula, Adamancipator, Coral Dragon, Lancea) provide different disruption angles.
- Hand-trap density (5 copies) offers reasonable going-second interaction.
- Graveyard recursion routes via Mermail effects support grinding.
Weaknesses
- ILLEGAL: Maxx C (Forbidden) and Bahamut Shark (Forbidden) present — deck cannot be used in official OCG play.
- Only 40% of core cards present (10 of 25 expected); heavy deviation into Atlantean/Mermail splash suggests unclear archetype identity.
- No side deck (0/15 slots) eliminates post-side adaptation; critical flaw for best-of-3.
- Missing several universal extra-deck staples listed as 100% inclusion (Infinite Impermanence, Dominus Impulse, Deep Sea Repetiteur, Graydle Dragon).
- Moulinglacia one-of requires exact 5 WATER in GY condition — fragile, situational payoff.
- No combo evidence means ceiling, median, and floor output are unverified; board quality unknown.
Critical choke points
- Forbidden cards in deck — structural illegality.
Recommended changes
| Priority | Remove | Add | Reason |
|---|---|---|---|
| 1 | Maxx "C" (Forbidden in OCG) | Infinite Impermanence or other staple negation | Maxx C is Forbidden; substituting with an in-format interaction tool restores legality. |
| 2 | Bahamut Shark (Forbidden in OCG) | Rank 4 WATER Xyz support or flex slot (e.g., LeVirtue Dragon if not already present) | Bahamut Shark is Forbidden; removing it and filling the slot clarifies the Extra Deck's role. |
| 3 | 15-card side deck | No side deck present; required for best-of-3 play. Recommend hand-trap flex (Veiler, Effect Veiler), board-break tech (Red Reboot), and archetype-specific counters. | |
| 4 | Moulinglacia the Elemental Lord (fragile conditional summoning) | Dominus Impulse or Deep Sea Repetiteur (core utility) | Moulinglacia requires 5 WATER GY and is a one-of; core Deep Sea cards are 100% inclusion and provide more reliable consistency. |
Evidence & confidence
- Verified: Legality status: Illegal (two Forbidden cards present); Deck size: 40 main, 15 extra, 0 side (constraints met for main/extra, side empty); Card text: Resolved for all 40 cards; Banlist status: Maxx C = Forbidden, Bahamut Shark = Forbidden (OCG)
- Observed: Usage statistics: Core card presence 40% (10 of 25); archetype spread shows heavy Atlantean/Mermail concentration; Composition: 5 hand-traps, 15 searchers, 7 negation-text, 10 removal-text
- Inferred: Engine consistency: P(>=1 archetype core starter in hand 5) ≈ 0.97; Combo ceiling: Trishula + Adamancipator board with 1-2 negations, inferred from Extra-Deck boss names and text; unverified without recorded lines; Combo floor: Estimated 2-3 Synchro/Xyz summons per line, moderate resource generation; Going-first plan: Synchro into disruption; going-second plan: hand-trap + removal; Interruption resilience: ~2 independent starter lines; Poseidra recovery available but contingent on board state; Board-breaking power: Forbidden Droplet + hand-traps present; unverified effectiveness
- Provisional: Meta Power: Null — no dated metagame sample supplied; archetype meta-share unavailable; Tournament Reliability: Unverifiable — no tournament context; Matchup coverage: Format fit unknown (Deep Sea niche, 40% core, heavy splash)
- Data gaps: Legality violation: Two Forbidden cards render the deck unplayable in OCG format. No side deck (0/15 slots) — cannot evaluate post-side adaptation. No combo evidence — combo ceiling, median, floor, power distribution, board_per_starter, and interaction_density all missing. No tournament context — archetype meta-share, per-pilot match record, and format-specific performance data absent. No win-rate telemetry — brick rate, starter rate, matchup outcomes, going-first/second split unverified. No guides — strategic intent and standard plays for this list unknown.
