Deck — Deck Power Evaluation

Final Contextual Deck Power: 35/100 (±10 · Confidence: Low)

• Primary strategy: Midrange
• Secondary strategies: Control
• Format: tcg

Legality

Main 57 / Extra 15 / Side 0 — status under the rules at evaluation time: Illegal. 6 violation(s).

Identity & game plan

• Win condition: Atlantean and Mermail boards built from Level 7 WATER monsters that go into Xyz and Link payoffs (Abysstrite, Poseidra Abyss is absent, Mermail Abyssgaios is single-copy, Poseidra, Mermail Abyssleed) and close with 2500+ ATK attackers (Inferred from card text; no recorded boards); Direct attacks from Atlantean Dragoons and Level 3 or lower Sea Serpents, plus Moulinglacia Special Summon control swings (Inferred)
• Turn 1 (going first): Open a starter such as Abyssrhine, Neptabyss or Mermail Abyssteus, search or summon a second WATER engine piece, then keep Ash Blossom, Infinite Impermanence or Ghost Ogre up for the opponent's first answer (Inferred)
• Turn 2 (going second): Hold a six-card hand with hand traps (Ash Blossom, Droll & Lock Bird, Ghost Ogre & Snow Rabbit, Ghost Belle, Infinite Impermanence, Evenly Matched) to stop the opponent's first board, then rebuild through Atlantean GY recursion (Inferred)
• Recovery: Recursion from the graveyard through Atlantean Dragoons, Mermail Shadow Squad and Atlantean Heavy Infantry, plus Mulcharmy Fuwalos draw when the hand is empty (Inferred from card text)
• After siding: Not available: the deck has no Side Deck, so no post-side plan exists

Why it scores here

The deck is scored as a system, not as an average of its cards. Its archetype core (26 copies of Atlantean, Mermail and Abyss- names) gives a 0.96 chance of at least one core card in the opening five, and each 3-copy starter has about a 0.24 chance of appearing in that hand (Inferred), so the engine is reasonably accessible. Twenty hand traps and about 10 negation effects give it real interaction, especially going second (0.94 for at least one hand trap in six cards, Inferred). Graveyard recursion through Dragoons, Shadow Squad and Heavy Infantry supports recovery after an interruption. The list is held back by three Forbidden cards in the Main and Extra Decks, two over-limit copies, 18.1% exact-name archetype purity, and no Side Deck, so it cannot adapt after siding. No recorded boards, tournament record, or guides exist, so the floor, median, and ceiling are text-only inferences. Popularity of the archetype was not credited, and the Illegal status caps the final score.

Dimension scores

How the score was computed

Strategy profile: Midrange. Structural ≈ 52.4, Going First ≈ 58, Going Second ≈ 60, Meta = provisional, Tournament Reliability ≈ 46. Modifiers: banlist exposure (-8); no side deck (-4). Final formula: No reliable metagame: 0.80*Structural + 0.20*TournamentReliability + ContextModifiers = 0.80*52.4 + 0.20*46 - 12 = 39; Illegal cap applied (legality status Illegal), final set to 35 (theoretical/structural-only)

Probability & combo summary

• Opening a starter: P(≥1) ≈ 0.24 · 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 archetype core (26 copies) gives a high chance of a live engine opening
• Twenty hand traps and about 10 negate effects provide layered interaction, especially going second
• Graveyard recursion through Atlantean and Mermail monsters supports recovery after disruption
• Extra Deck covers Xyz, Link and Synchro payoffs with several distinct boss monsters

Weaknesses

• Illegal list: three Forbidden cards and two over-limit copies
• No Side Deck, so no post-side plan and no matchup adaptability
• Low exact-name purity (18.1%) with many splash and staple cards dilutes the engine
• Hand-trap-heavy hands risk dead cards when no starter is present

Critical choke points

• Forbidden Called by the Grave and Triple Tactics Talent cannot be legally played in TCG
• The Level 7 WATER starter line depends on a small number of multi-copy engine pieces
• Hand traps are dead when the opponent does not activate effects

Recommended changes

Evidence & confidence

• Verified: Main 57, Extra 15, Side 0 are inside the TCG size rules; Called by the Grave, Triple Tactics Talent and Trishula are Forbidden in TCG (BanList); Ash Blossom & Joyous Spring (3 copies, 2 legal) and Droll & Lock Bird (3 copies, 1 legal) exceed copy limits; Zero Side Deck cards; 18.1% exact-name archetype purity; 26 archetype-core copies
• Inferred: Starter accessibility from hypergeometric odds (0.24 per 3-copy card, 0.96 for the core group); Hand-trap coverage 0.94 going second; Interaction and recursion breadth from card text; Going-first and going-second plans from card text
• Provisional: Format fit and matchup coverage (no tournament link or dated meta sample); Floor and median output (no recorded boards)
• 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 are absent No win-rate telemetry (going-first/second, matchup, brick and starter rates) exists in YGOVN Meta Power is Provisional because no dated metagame sample was supplied No guides for the archetype and no title on the deck
