Atlantean Deck #770819 — Yu-Gi-Oh! OCG

Deck — Deck Power Evaluation

Final Contextual Deck Power: 35/100 (±8 · Confidence: Low)

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

Legality

Main 55 / Extra 15 / Side 0 — status under the rules at evaluation time: Illegal. 2 violation(s).

Identity & game plan

• Win condition: Atlantean and Abyss/Mermail Xyz and Link boards built from Poseidra, Levia-Dragon - Daedalus, Abysstrite and the Atlantis/Umi Link Monsters (structural read; no recorded boards); Direct attacks from Atlantean Dragoons, which lets Level 3 or lower Sea Serpent monsters attack directly
• Turn 1 (going first): Open on a Mulcharmy or Neptabyss starter, search or set up Atlantis, City of the Sea Dragon, and protect the starter with Ash Blossom, Ghost Belle, Ghost Ogre or Solemn Judgment (Inferred from text)
• Turn 2 (going second): Hold Ash Blossom, Ghost Belle, Ghost Ogre, Droll & Lock Bird and Solemn Warning to stop the opponent's first summon, then convert the surviving starter into an Extra Deck board (Inferred)
• Recovery: Recover through Mermail Abysspike, Mermail Abyssteus, Warchief of Atlantis and Deep Sea Minstrel, which add or revive monsters from the GY (Inferred from text)
• After siding: No side deck is registered, so there is no post-side plan. The side is 0 cards and the deck cannot adjust between games

Why it scores here

The score is built from the deck as a system and not from averaging card scores. Access is decent: the archetype core (19 copies) has about an 89% chance of at least one card in a 5-card opening hand (hypergeometric, Inferred), and there are several starters. Interaction is the strongest area: about 10 hand traps and roughly 19 negation-text cards give layered answers, and Droll & Lock Bird and Skill Drain add floodgate-like control. Consistency is held back by the mix. Only 15.7% of the main deck is the exact Atlantean name, and the rest is spread across Mulcharmy, Mermail, Abyss, Daedalus, Dominus, Solemn, Kaiju and others, which adds brick risk and conflicting Normal Summon lines. There is no recorded combo data, no tournament link and no side deck, so the floor, median and ceiling are text-only inferences. Popularity did not earn points: the archetype-standard core is only 60% present, and this list was penalised for the over-limit Ash Blossom and Dominus Impulse and for the Limited cards.

Dimension scores

How the score was computed

Strategy profile: Midrange. Structural ≈ 49.5, Going First ≈ 45, Going Second ≈ 50, Meta = provisional, Tournament Reliability ≈ 35. Modifiers: Illegal: copy-limit violations (-10); Banlist exposure (-2). Final formula: 0.80*Structural + 0.20*TournamentReliability (Meta provisional) + ContextModifiers; Illegal cap applied (theoretical/structural-only)

Probability & combo summary

• Opening a starter: P(≥1) ≈ — · 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: 10 hand traps, 19 negation-text cards and two Solemns
• Multiple starters with high archetype-core access (~89% for at least one in a 5-card hand)
• Closing threats in Poseidra, Levia-Dragon and Poseidra Abyss

Weaknesses

• Illegal list: Ash Blossom and Dominus Impulse are over the copy limit
• Low exact-archetype purity (15.7%) and loose engine coherence
• No side deck, so there is no post-side adaptation
• No recorded boards, so the combo ceiling and median are unmeasured

Critical choke points

• Atlantis, City of the Sea Dragon is a single copy that many engines need
• Droll & Lock Bird, Skill Drain and Solemn Judgment are single Limited copies and cannot be replaced

Recommended changes

Evidence & confidence

• Verified: Legality: Illegal, with 55 Main, 15 Extra and 0 Side cards; Copy-limit violations: Ash Blossom and Dominus Impulse at 3 copies each against a limit of 2; Banlist: Droll & Lock Bird, Skill Drain and Solemn Judgment are Limited at 1 copy each; Solemn Warning is Semi-Limited; Composition: 15.7% exact-name archetype purity; 10 hand traps; 15 Extra Deck cards
• Inferred: Opening-hand access is estimated hypergeometrically (~0.89 for the core); Interaction quality is a semantic read of the card text
• Provisional: Meta Power is null because no dated metagame sample exists; Matchup and format fit are a guess because no tournament data exists
• Data gaps: No combos supplied: floor, median and ceiling are text-only inference No tournament link: archetype meta-share and per-pilot match record absent No win-rate telemetry exists in YGOVN (going-first/second, matchup, brick and starter rates) Meta Power is Provisional unless a dated metagame sample is supplied No side deck registered
