Atlantean Deck #771858 — Yu-Gi-Oh! OCG

Deck — Deck Power Evaluation

Final Contextual Deck Power: 36/100 (±10 · Confidence: Low)

• Primary strategy: Midrange
• Secondary strategies: Stun, Toolbox
• Format: ocg

Legality

Main 59 / Extra 15 / Side 0 — status under the rules at evaluation time: Illegal. 2 violation(s).

Identity & game plan

• Win condition: Extra Deck boss monsters (Poseidra Abyss, Abysstrite, Azure Ocean Dragon Lord, Mermail Abyssgaios) reached through Atlantean and Mermail summon chains (card text read, Inferred); Atlantean Dragoons direct attacks for Level 3 or lower Sea Serpents (card text read, Inferred)
• Turn 1 (going first): Open on Neptabyss, Mermail Shadow Squad, or Mulcharmy draw engines, then extend into a Level 7 or higher Extra Deck monster through the Atlantean and Mermail chain (Inferred)
• Turn 2 (going second): Hold Ash Blossom, Evenly Matched, Droll & Lock Bird, and the Solemn trio to answer the opponent's first summon, then rebuild the Atlantean chain (Inferred)
• Recovery: Searchers (18 search-text cards) and Mulcharmy draw effects refill the hand after a board wipe (Inferred)
• After siding: No side deck is registered, so there is no post-side plan (Verified: side_count 0)

Why it scores here

This is a theoretical, structural-only read: the list is Illegal (Ash Blossom and Dominus Impulse each run 3 copies against a Semi-Limited limit of 2), so it does not receive a normal Final Contextual score. Its structural core is reasonable: the 96% hypergeometric chance of at least one archetype-core card in a 5-card opener (Inferred) and 18 search-text cards support a playable T1 engine. Interaction is the strongest area, with 15 negation-text cards and 6 hand traps giving layered answers to the first summon. Consistency is capped by an exact-name Atlantean purity of only 16.2% (62 off-archetype copies), an Extra Deck padded with off-theme monsters, and a missing side deck; there are no recorded boards, so the ceiling and median are inferred from card text only. The score was built from consistency, interaction and the system's structure, not from averaging card scores, and the deck's popularity (Atlantean core usage) earned no points.

Dimension scores

How the score was computed

Strategy profile: Midrange. Structural ≈ 50, Going First ≈ 48, Going Second ≈ 52, Meta = provisional, Tournament Reliability ≈ 42. Modifiers: Illegal copy limit (Ash Blossom & Joyous Spring, Dominus Impulse at 3 copies vs 2 legal) (-10); Banlist exposure (Limited 1-copy staples: Droll & Lock Bird, Solemn Judgment, Instant Fusion, One for One) (-2). Final formula: 0.80*Structural + 0.20*TournamentReliability (Meta provisional) = 0.80*50 + 0.20*42 = 48.4; modifiers -12 -> 36.4; Illegal list, so theoretical only

Probability & combo summary

• Opening a starter: P(≥1) ≈ 0.96 · 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

• Layered interaction: 15 negation-text cards and 6 hand traps (Verified text flags)
• Archetype core opens reliably: 96% chance of at least one core card in a 5-card opener (Inferred)
• Searcher density (18 search-text cards) supports consistency and recovery (Inferred)
• High-ATK Extra Deck closers (Poseidra 2800, Poseidra Abyss 3000, Icejade Gymir 3000) (Verified stats)

Weaknesses

• Illegal: two cards over the Semi-Limited copy limit (Verified)
• Low exact-name Atlantean purity (16.2%); 62 off-archetype copies weaken the engine (Verified)
• Off-theme Extra Deck cards (Swordsoul, Adamancipator, Icejade) while 5 core usage cards are missing (Observed)
• No side deck (Verified)
• No recorded combos; floor, median and ceiling cannot be measured (Verified gap)

Critical choke points

• Ash Blossom and Dominus Impulse are over the copy limit, so the list cannot be played as built (Verified)
• Atlantis, City of the Sea Dragon is a single copy and gates the Umi and Daedalus lines (Verified text)
• Solemn Judgment, Droll & Lock Bird, Instant Fusion and One for One are Limited to one copy each (Verified)

Recommended changes

Evidence & confidence

• Verified: Legality: Ash Blossom and Dominus Impulse over the copy limit; Main 59 and Extra 15 are inside OCG size rules; Side deck is empty; Card text and stats for the listed cards; Copy histogram and composition counts
• Observed: Usage stats: 14 of 24 core cards present; Abysstrite, Marincess, LeVirtue, Abyssgaios and Poseidra Abyss missing
• Inferred: Opening and hand-trap probabilities from the hypergeometric table; Strategy label (Midrange) and profile weights; Dimension scores D1-D14 and the structural score; Recovery and going-first/going-second plans
• Provisional: Meta power (null); Matchup coverage and format fit (D13); 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 match record are absent No win-rate telemetry (going-first/second, matchup, brick/starter rates); those signals are Inferred or Unknown Meta power is provisional without a dated metagame sample Side deck is empty
