Atlantean Deck #768453 — Yu-Gi-Oh! OCG

Deck — Deck Power Evaluation

Final Contextual Deck Power: 20/100 (±8 · Confidence: Low)

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

Legality

Main 41 / Extra 15 / Side 0 — status: Illegal. 1 violation(s).

Identity & game plan

• Win condition: Extra Deck boss monsters (Azure Ocean Dragon Lord - Neo-Daedalus Rage, Levia-Dragoon - Daedalus, Abysstrite) built from Atlantean and Umi searches, with Poseidra and Atlantean Dragoons as board pressure. Bahamut Shark is an illegal Xyz in this list.; Atlantis, City of the Sea Dragon and Umi field-based Level and ATK pressure; Daedalus Maelstrom and Call of Atlantis as interaction and follow-up.
• Turn 1 (going first): Summon Atlantean or Penguin starters (First Penguin, Neptabyss, Mulcharmy Purulia, Fish Sonar), search a second Atlantean piece, and link or Xyz into a Level 7 or 4 boss. Inferred from card text; no combo corpus.
• Turn 2 (going second): Respond to the opponent's summon with Ash Blossom, Maxx C, Droll and Lock Bird, or Dominus Impulse, then rebuild the board with searched Atlanteans and a Link or Xyz boss.
• Recovery: Warchief of Atlantis and Advent of Atlantis recur or search Umi cards from the GY and Field Zone; Atlantean Dragoons and Monster Arms can restore a board. Inferred.
• After siding: Not applicable. The deck has 0 side-deck cards, so no post-side plan exists.

Why it scores here

This deck is illegal in OCG as submitted: it runs 2 copies of Bahamut Shark, which is Forbidden, so it receives a structural-only score capped at 20 rather than a normal Final Contextual score. Its system read is still informative: a searcher-dense Atlantean and Umi core (P(at least one searcher in a 5-card opening) ~0.97) gives reasonable engine access, and the 3-copy starters plus Warchief and Advent give recursion. Interaction is solid for the format (Ash Blossom x2, Dominus Impulse x2, Maxx C, Droll and Lock Bird, Daedalus Maelstrom), but there is no side deck, no recorded combos, and no tournament data, so combo ceiling, median, and matchup fit stay Inferred or Provisional. The score comes from consistency, interaction, and the system's engine cohesion, not from averaging the individual card scores and not from the archetype's popularity.

Dimension scores

How the score was computed

Strategy profile: Midrange. Structural ≈ 51, Going First ≈ 52, Going Second ≈ 45, Meta = provisional, Tournament Reliability ≈ 45. Modifiers: Banlist exposure (-6). Final formula: Pre-cap: 0.80*Structural(51) + 0.20*TournamentReliability(45) + modifiers(-6) = 44; capped to 20 because the deck is Illegal (Forbidden Bahamut Shark x2). Meta Power provisional.

Probability & combo summary

• Opening a starter: P(≥1) ≈ 0.33 · 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

• Searcher density (20 searcher-text cards) keeps the engine live across openings
• Layered interaction: 4 hand traps plus Daedalus Maelstrom, Virtue Stream, and Call of Atlantis
• Strong Extra Deck boss options with Link and Xyz routes into Umi and Atlantis pressure

Weaknesses

• Illegal as submitted: Bahamut Shark x2 is Forbidden
• No side deck, so no post-side plan and no adaptability
• Low exact-name purity (14.3%), so the engine depends on loosely related sub-archetypes
• No recorded combos, so combo conversion and median output cannot be measured

Critical choke points

• Bahamut Shark occupies an Extra Deck slot and is illegal; the deck must remove it to be playable
• Umi and Atlantis field effects depend on keeping Atlantis, City of the Sea Dragon or Warchief live

Recommended changes

Evidence & confidence

• Verified: Legality: 41 Main, 15 Extra, 0 Side; Bahamut Shark (Forbidden) run 2x with a limit of 0; Card text and stats for all 24 distinct main and 12 distinct extra cards; Usage stats: 36 rows, 11 of 25 core cards present (44%)
• Inferred: Consistency and starter-live probabilities from the hypergeometric draw table; Interaction quality from text and role tags; Going-first and going-second plans from card text
• Provisional: Meta Power and matchup fit: no dated metagame sample and no tournament 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 absent No side deck; post-side plan cannot be assessed No win-rate telemetry; going-first, going-second, and matchup rates unknown Meta Power provisional without a dated metagame sample
