Atlantean Deck #768079 — Yu-Gi-Oh! OCG

Deck — Deck Power Evaluation

Final Contextual Deck Power: 30/100 (±8 · Confidence: Low)

• Primary strategy: Midrange
• Secondary strategies: Tempo
• Format: ocg

Legality

Main 55 / Extra 15 / Side 0 — status: Illegal. 2 violation(s).

Identity & game plan

• Win condition: Atlantean/Mermail/Abyss- board of 2800-3000 ATK Extra Deck monsters (Poseidra, Abyssgaios, Coelacanth, Monoceros) built through searcher-driven Level 7 WATER summons; Xyz and Link bosses (LeVirtue Dragon, Poseidra Abyss, Abysstrite, Mermail King - Neptabyss) that extend the board
• Turn 1 (going first): Open a WATER starter (Neptabyss, Mermail Abyssteus, Atlantean Dragoons, Mermail Abysspike) and search a second Atlantean/Mermail piece, then convert to a Level 7 WATER Synchro or Xyz boss; hold Ash Blossom / Evenly Matched for the first interaction
• Turn 2 (going second): Use Ash Blossom, Infinite Impermanence, Ghost Belle and Nibiru to answer the opponent's first summon, then rebuild through Mermail Abyssteus / Abysspike searches into a boss
• Recovery: Recover through Atlantean/Mermail searchers (Neptabyss, Abysspike, Abyssteus, Abyssalacia) and Deep Sea Minstrel recursion from the GY
• After siding: Not evaluable: the deck runs no Side Deck, so there is no post-side plan

Why it scores here

This OCG Atlantean list reliably opens a WATER starter and searches a second Atlantean or Mermail piece: 14 archetype-core copies give roughly a 78% chance of at least one in a 5-card opening hand (Inferred). Conversion to Level 7 Synchro and Xyz bosses is plausible from the card text, but no recorded boards exist, so the ceiling and median are text-based inference only. Interaction is dense (14 hand traps, Ash Blossom, Infinite Impermanence, Mermail Abyssgaios negation), which supports going-second play, yet the 57 off-archetype copies, 14 hand traps and absence of a side deck pull the structure down. Popularity (archetype usage stats) confirms the list is accessible but was not credited as power, and the card scores were not averaged. The list is Illegal (two cards over copy limit), so the final score is capped and labelled structural-only.

Dimension scores

How the score was computed

Strategy profile: Midrange only; Tempo tilt not applied to weights. Structural ≈ 52, Going First ≈ 55, Going Second ≈ 60, Meta = provisional, Tournament Reliability ≈ 40. Modifiers: banlist_exposure (-4); no_side_deck (-3); illegal_list_cap (-13). Final formula: Raw: 0.80*Structural(52) + 0.20*TournamentReliability(40) + modifiers(-7) = about 43; capped to 30 because the list is Illegal. Meta provisional. Theoretical/structural-only.

Probability & combo summary

• Opening a starter: P(≥1) ≈ 0.78 · key two-card combo ≈ — · full-brick estimate ≈ 0.22 (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 coverage (14 hand traps, 13 negation-text cards)
• Multiple Level 7 WATER boss routes into 2800-3000 ATK bosses
• Many searchers and GY recursion for resource regeneration

Weaknesses

• Illegal list: Ash Blossom and Dominus Impulse each run 3 copies against an OCG limit of 2
• No Side Deck at all
• Low archetype purity (18.6%) across many sub-archetypes

Critical choke points

• Dependence on WATER Level 7 summons and Synchro/Xyz material from a small set of starters
• Single Atlantean/Mermail starter in hand creates a conversion bottleneck when hand traps are used first

Recommended changes

Evidence & confidence

• Verified: Main 55, Extra 15, Side 0 are within OCG size rules; Ash Blossom and Dominus Impulse each run 3 copies over the Semi-Limited limit of 2; One for One and Pot of Prosperity are Limited and run 1 copy each (legal); Card text and stats from the resolved evidence
• Inferred: Opening-hand probabilities (hypergeometric); Going-first and going-second estimates; Consistency, brick and interaction quality
• Provisional: Meta power (no dated metagame sample); Matchup and tournament reliability
• Data gaps: No combos supplied: combo floor, median and ceiling are text-only inference No tournament link: archetype meta-share and per-pilot record absent No win-rate telemetry for going-first, going-second or matchups Meta Power is provisional without a dated metagame sample Deck has no title and no side deck
