Atlantean Deck #768949 — Yu-Gi-Oh! OCG

Deck — Deck Power Evaluation

Final Contextual Deck Power: 40/100 (±10 · Confidence: Low)

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

Legality

Main 58 / Extra 15 / Side 0 — status under the rules at evaluation time: Illegal. 2 violation(s).

Identity & game plan

• Win condition: Atlantean and Mermail boards converted into Poseidra, Abysstrite, Atlantean Dragoons and Abyss-line Xyz/Link pressure (Inferred from card text; no recorded boards); Levia-Dragon - Daedalus and Atlantis/Umi Link routes (Inferred from card text)
• Turn 1 (going first): Open a WATER starter (Neptabyss, Abyssrhine, First Penguin, Mulcharmy) to search an Atlantean or Mermail engine piece, then build a Synchro or Xyz board (Inferred)
• Turn 2 (going second): Use the 11 hand traps and Ash Blossom to stop the opponent's first summon, then extend through Deep Sea and Mermail monsters (Inferred)
• Recovery: Mermail Abyssteus and Mermail Abysspike search lower-level Mermail or WATER monsters; Mulcharmy draw effects refill the hand (Inferred)
• After siding: Not evaluable: the deck runs no Side Deck (side_count 0)

Why it scores here

The deck is illegal in OCG as submitted: Ash Blossom & Joyous Spring and Dominus Impulse are each run three times against a Semi-Limited limit of two, so the score is a theoretical structural read capped at 40, not a normal final score. Structurally the list has real redundancy: the Atlantean/Mermail core has a 94.8% chance of at least one piece in a 5-card opening hand, and 20 searcher-text cards support a consistent engine start (Inferred from hypergeometric estimates). Interaction is dense, with 11 hand traps and 14 negation-text cards, which gives a 73% chance of at least one hand trap in a 6-card going-second hand (Inferred). Scores come from consistency and interaction on the system, not from averaging card power and not from Atlantean's popularity, which is only the archetype-usage signal. Points are limited by 61 off-archetype copies (16.4% exact-name purity), no side deck, no recorded boards, and multi-step Umi and Atlantis conditions.

Dimension scores

How the score was computed

Strategy profile: Midrange. Structural ≈ 58.9, Going First ≈ 62, Going Second ≈ 60, Meta = provisional, Tournament Reliability ≈ 50. Modifiers: banlist_exposure (-4); no_side_deck (-3); no_combo_evidence (-2); illegal_cap (0). Final formula: No reliable metagame: 0.80*Structural + 0.20*TournamentReliability + ContextModifiers = 0.80*58.9 + 0.20*50 - 9 = 48.1; capped at 40 because the list is Illegal (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

• Core engine has high redundancy: 94.8% chance of at least one archetype-core card in a 5-card hand (Inferred)
• Dense interaction: 11 hand traps and 14 negation-text cards (Inferred)
• Multiple searchers and draw effects keep resources flowing (Inferred)

Weaknesses

• Illegal as submitted: two cards exceed OCG copy limits (Verified)
• Low exact-archetype purity (16.4%) with 19 sub-archetypes diluting the engine (Verified)
• No side deck (Verified)
• No recorded combos to measure real conversion (Verified)

Critical choke points

• Umi and Atlantis conditions gate several Link and Synchro routes (Inferred)
• Dependence on Atlantis, City of the Sea Dragon in the field-spell line (Inferred)

Recommended changes

Evidence & confidence

• Verified: Ash Blossom & Joyous Spring and Dominus Impulse exceed the OCG copy limit (3 run vs 2 legal); Main 58 and Extra 15 are within the OCG size rules; Exact-name purity 16.4%; side deck is empty; Archetype core group: 25 copies, 48% core-card presence
• Inferred: Consistency estimates from hypergeometric probabilities; Interaction density from role-hint and card-text scaffold; Going-first and going-second plans from card text
• Provisional: Meta Power and matchup fit: no dated metagame sample; Median and floor output: no combo data
• Data gaps: No combos supplied: combo floor, median and ceiling are text-only inference No tournament link: archetype meta-share and per-pilot record are absent No win-rate telemetry (going-first, matchup, starter or brick rates) Meta Power is Provisional without a dated metagame sample No side deck supplied for a best-of-3 post-side read
