Atlantean Deck #768066 — Yu-Gi-Oh! OCG

Deck — Deck Power Evaluation

Final Contextual Deck Power: 39/100 (±8 · Confidence: Low)

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

Legality

Main 48 / Extra 17 / Side 0 — status under the rules at evaluation time: Illegal. 1 violation(s).

Identity & game plan

• Win condition: Extra-Deck beatdown through Poseidra, Abyssleed and Abyssgaios once the searcher chain reaches the boss monsters; Direct attacks from Atlantean Dragoons plus Abyss-scale negation on opposing effects
• Turn 1 (going first): Normal Summon Mermail Abysspike, Abyssturge or Swap Frog to add a WATER/Mermail follow-up, then Special Summon a Mermail boss from hand (Abyssleed, Abyssmegalo or Abysstrite) and use Abyssalacia or Abysstrite to stabilise
• Turn 2 (going second): Hand-quality dependent: no hand traps or floodgates in the list, so the going-second plan relies on Mermail Abyssocea or Abyssteus searching a Mermail boss and on Abyss-squall or Abyss-steam to answer the first board
• Recovery: Mermail Abyssgunde and Abyssturge recurse Level 3/4 WATER monsters from the GY; Deep Sea Aria and Abyss-sting Triaina also recover from the GY
• After siding: Not evaluable: side_count is 0 in the export, so no side plan exists to score

Why it scores here

The deck reliably opens a searcher chain: 22 searcher-text cards give about a 96% chance of at least one searcher in a 5-card opening hand, and the 10 archetype-core copies give about 71% at least one in hand, so the engine is usually live by turn 2 (Inferred). Its ceiling comes from Extra-Deck bosses such as Poseidra Abyss, Mermail Abyssgaios and Mermail Abyssleed, which give real closing power, but no recorded boards exist so the floor and median are text-based estimates only. Interaction is mostly conditional: 11 removal-text and 6 negation-text cards, with no hand traps or floodgates, which weakens going-second play. The score is not driven by Atlantean being a popular archetype, and card scores were not averaged. The Extra Deck has 17 cards against an OCG maximum of 15, so this is structural-only and the score is capped low.

Dimension scores

How the score was computed

Strategy profile: Midrange. Structural ≈ 52, Going First ≈ 55, Going Second ≈ 35, Meta = provisional, Tournament Reliability ≈ 45. Modifiers: illegal extra-deck size (-12). Final formula: 0.80*Structural(52.5) + 0.20*TournamentReliability(45) + modifiers(-12) = 39; illegal deck, theoretical/structural-only; Meta provisional

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

• Searcher density gives high opening-hand access to the engine (~96% at least one searcher in 5 cards)
• Multiple Extra-Deck bosses with strong ATK (Poseidra Abyss 3000, Abyssleed 2700 in Main, Poseidra 2800)
• Several GY recursion routes support resilience after one interruption

Weaknesses

• Extra Deck of 17 is illegal in OCG (max 15)
• No hand traps or floodgates; weak going-second interaction
• No recorded combos, so ceiling and median cannot be measured
• Low exact-archetype purity (18.5%) with many cross-archetype cards
• No side deck in the export, so no post-side evaluation

Critical choke points

• Extra Deck legality: must cut to 15 before any normal score applies
• Reliance on a Mermail or Atlantean boss summon through GY-cost conditions

Recommended changes

Evidence & confidence

• Verified: Extra Deck count 17 exceeds OCG max 15; Main Deck 48 is within 40-60; All cards at copy limits (max 3, Unlimited); 22 searcher-text cards, 6 negation-text, 11 removal-text
• Inferred: Searcher hypergeometric access ~0.96 and core ~0.71 in hand; Structural dimension scores and midrange weights; Going-second weakness from absent hand traps
• Provisional: Meta Power (null, no dated sample); Format fit D13 (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 in export; post-side and best-of-3 cannot be scored No win-rate telemetry; going-first/second and matchup are Inferred Meta Power is provisional without a dated metagame sample
