Deck — Deck Power Evaluation

Final Contextual Deck Power: 35/100 (±8 · Confidence: Low)

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

Legality

Main 58 / Extra 15 / Side 0 — status under the rules at evaluation time: Illegal. 8 violation(s).

Identity & game plan

• Win condition: Atlantean/Abyss-/Mermail Xyz, Link and Synchro boards (Poseidra Abyss, Mermail King - Neptabyss, Abyssgaios-type boards) built from Neptabyss and Abyssrhine searches; Poseidra, the Storming Atlantean (2800 ATK) and Atlantean Dragoons direct-attack pressure
• Turn 1 (going first): Search a Mermail/Atlantean starter with Neptabyss, Abyssrhine or Mermail Abyssteus, then convert into a Level 7 Xyz or Link via Mermail Shadow Squad and Abysspike recursion (Inferred from card text)
• Turn 2 (going second): Hold Ash Blossom, Dominus Impulse and Droll & Lock Bird for the opponent's first engine summon, then rebuild through Mulcharmy draws (Inferred from card text; the illegal copy counts make this list unplayable as built)
• Recovery: Recycle Atlantean and Mermail monsters from the GY with Mermail Shadow Squad, Atlantean Dragoons and Poseidra GY effects, and draw through the Mulcharmy monsters (Inferred from card text)
• After siding: No side deck is present, so there is no post-side plan (data gap)

Why it scores here

This deck is scored as a connected system, not as an average of its card scores. Its engine is reliable on paper: the archetype-core group is present in 99% of hands with five cards, and the searcher group (15 copies) gives about a 79% chance of at least one searcher in the opening five (Inferred, hypergeometric). Its interaction layer (5 hand traps, 15 negation-text cards, 16 removal-text cards) is dense enough to contest the opponent's first engine summon. Its closing power comes from several 2800–3000 ATK Xyz, Link and Synchro bosses in the Extra Deck. Its weaknesses are a large brick and tech component (14 tech cards, several spells that are dead without a specific board), no side deck, and no combo or board evidence to confirm conversion. The legality cap is the decisive factor: four Forbidden cards and four copy-limit violations make this list unplayable as built, so this score is structural and theoretical only. Popularity and archetype usage were not counted as power.

Dimension scores

How the score was computed

Strategy profile: Midrange primary, Toolbox consulted for D11 and D8 interpretation only (no weight change). Structural ≈ 57, Going First ≈ 58, Going Second ≈ 52, Meta = provisional, Tournament Reliability ≈ 40. Modifiers: Banlist exposure (-8); Weak post-side plan (-4). Final formula: Structural 57.2; pre-cap Final = 0.80*57.2 + 0.20*40 + modifiers(-12) = 41.8; Illegal legality cap applied, final 35 (theoretical/structural-only)

Probability & combo summary

• Opening a starter: P(≥1) ≈ 0.79 · 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

• Archetype-core searcher density (Neptabyss, Abyssrhine, Mermail Abyssteus) gives a high chance of a live engine
• Layered hand-trap and negation coverage on the opponent's first summon
• Multiple 2800–3000 ATK bosses across the Extra Deck, including Poseidra Abyss

Weaknesses

• Illegal as built: four Forbidden cards and four copy-limit violations
• No side deck, so no matchup adaptation
• Heavy tech and situational-spell load (14 tech cards) raises brick risk
• Low archetype purity (16.4%) reflects a cross-sub-archetype build with unclear routing

Critical choke points

• Legal copy-limit correction must remove Forbidden cards before the deck can be played as built
• Hand traps depend on specific hand-timing; with no side deck, a single extra interruption ends the turn

Recommended changes

Evidence & confidence

• Verified: Main 58 / Extra 15 / Side 0 counts; four Forbidden cards; copy-limit violations listed in legality; Archetype core present at 100% inclusion in usage stats for Neptabyss, Abyssrhine, Ash Blossom, Atlantean Dragoons
• Inferred: D1 starter reliability (79% searcher, 99% core); D7 interaction density from text tags; Going-first/second plans from card text
• Provisional: Meta Power (no dated metagame sample); D13 matchup fit (no tournament link); D4 median output (no boards)
• Data gaps: No combos supplied: combo floor/median/ceiling is text-only inference No tournament link: archetype meta-share and per-pilot record absent No side deck: no post-side evidence No win-rate telemetry for this deck; brick/starter/OTK rates are Inferred or Unknown usage statistics marks Abysstrite and LeVirtue Dragon as not in deck, but the resolved card list includes both; the resolved card list was used as the source of truth
