Deck — Deck Power Evaluation

Final Contextual Deck Power: 25/100 (±8 · Confidence: Low)

• Primary strategy: Combo
• Secondary strategies: Midrange, Stun
• Format: tcg

Legality

Main 55 / Extra 15 / Side 0 — status under the rules at evaluation time: Illegal. 6 violation(s).

Identity & game plan

• Win condition: Xyz and Link bosses (Poseidra Abyss, Mermail Abyssgaios, Worldsea Dragon Zealantis) reached through Atlantean and Mermail searcher chains; Level 7 Mermail Abyssmegalo second attack and direct attacks from Atlantean Dragoons
• Turn 1 (going first): Open a searcher or tuner starter, search a Mermail or Atlantean monster, and build toward a Xyz or Link boss; hold Ash Blossom and Infinite Impermanence for the opponent's first response
• Turn 2 (going second): Use hand traps (Ash Blossom, Infinite Impermanence, Artifact Lancea) to stop the opponent's board, then rebuild through GY-revived WATER monsters
• Recovery: Recur WATER monsters from the Graveyard (Mermail Abyssgunde, Mermail Abysspike, Gluttonous Reptolphin Greethys) and rebuild with searchers
• After siding: No side deck is registered, so no post-side plan can be evaluated

Why it scores here

The list is illegal: four Forbidden cards are included and three other cards exceed their copy limits, so the score is capped and reflects structure only. Structurally the deck opens reasonably often, because about 15 searcher cards and an 11-copy archetype core give roughly an 81% chance of at least one searcher in the opening five and about a 69% chance of at least one core card. Its interaction suite (hand traps and negation text) is broad and is strongest on the second turn. Its finishing bosses are strong, but there are no recorded boards or guides to show how often they are actually reached, so the conversion and median scores rest on inference. No side deck and no tournament or matchup data lower the reliability and matchup scores. Archetype popularity was not credited, and card scores were not averaged into the deck score.

Dimension scores

How the score was computed

Strategy profile: Combo. Structural ≈ 51.7, Going First ≈ 50, Going Second ≈ 55, Meta = provisional, Tournament Reliability ≈ 42. Modifiers: banlist exposure (-12); illegal-list cap (-12.8). Final formula: Illegal cap: 0.80*Structural(51.7) + 0.20*TournamentReliability(42) = 49.8, then modifiers -12 gives 37.8, then capped at 25 for an illegal list (theoretical/structural only)

Probability & combo summary

• Opening a starter: P(≥1) ≈ 0.81 · 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 searcher chains into Mermail and Atlantean payoffs
• Broad negation and hand-trap suite that works on the second turn
• Strong Xyz and Link bosses with high ATK

Weaknesses

• Illegal copy counts and Forbidden cards
• No side deck for best-of-three rounds
• High dependence on hand traps that can be dead in hand

Critical choke points

• Forbidden cards must be removed before the list can be played
• Most engine lines need WATER monsters in the Graveyard, which a clean opening may lack

Recommended changes

Evidence & confidence

• Verified: Main 55, Extra 15, Side 0 are within the size rules; Four Forbidden cards and three over-limit cards are present; Card texts and archetype breakdowns match the evidence
• Inferred: Hypergeometric opening estimates; Hand-trap dead-hand rate; Combo ceiling and median read from card text
• Provisional: Matchup and format fit (no dated meta sample); Meta Power (null)
• Data gaps: No combos supplied; conversion and median are text-only inference No tournament link; archetype meta-share and match record are absent No win-rate telemetry; going-first and going-second splits are unknown No side deck; post-side plan cannot be assessed Meta Power is provisional without a dated metagame sample
