Atlantean Deck #775051 — Yu-Gi-Oh! OCG

Deck — Deck Power Evaluation

Final Contextual Deck Power: 25/100 (±10 · Confidence: Low)

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

Legality

Main 57 / Extra 15 / Side 0 — status under the rules at evaluation time: Illegal. 2 violation(s).

Identity & game plan

• Win condition: Atlantean/Atlantis Extra Deck beaters (Poseidra, Levia-Dragon, Atlantean Dragoons direct attacks) carried by the Atlantean engine and Mulcharmy draws; Mermail/Abyss Xyz and Link closers (Mermail Abyssgaios, Abysstrite, Mermail King - Neptabyss) once the board is established
• Turn 1 (going first): Open a starter (Neptabyss, Warchief, Mulcharmy Purulia, Atlantis) and search into the Atlantean Extra Deck summon route while holding Solemn and Droll-style interaction for the opponent's first big play
• Turn 2 (going second): Use the 10 hand traps and Maxx C to break the opponent's first summon, then convert the remaining Atlantean board into an Extra Deck beater
• Recovery: Mulcharmy draw effects, Maxx C and Mermail Shadow Squad recursion to rebuild the hand after a board wipe or Forbidden-free interaction exchange
• After siding: Not applicable: the deck has no Side Deck (Side Deck size 0), so no post-side plan exists

Why it scores here

The deck reliably opens its Atlantean engine: the 26 core-archetype copies give a 0.96 hypergeometric chance of at least one core card in a 5-card opening hand, so the starter access is strong (Inferred). Its interaction package (10 hand traps, Solemn Judgment, Droll and Red Reboot-style answers, Daedalus Maelstrom) earns most of its points, because it can answer several common first plays and keep the board under control. Conversion and floor scores stay moderate because no recorded boards exist, so the combo ceiling and median output are text-only inferences rather than observed results. Popularity (Atlantean usage stats) confirms the list is real and accessible but did not earn points by itself, and the individual card scores were not averaged into the deck score. The final score is capped at 25 because the list runs two Forbidden cards (Bahamut Shark and Barrier Statue of the Torrent) and has no Side Deck, so it cannot receive a normal Final Contextual score.

Dimension scores

How the score was computed

Strategy profile: Midrange primary; Toolbox secondary not blended (no separate profile weights applied). Structural ≈ 54, Going First ≈ 50, Going Second ≈ 58, Meta = provisional, Tournament Reliability ≈ 42. Modifiers: Banlist exposure (-12); Illegal cap (-15). Final formula: No reliable metagame: 0.80*Structural(54.4) + 0.20*TournamentReliability(42) = 52, then modifiers (-12) = 40, then Illegal cap applied = 25 (theoretical/structural-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

• Core engine access is strong: 26 archetype-core copies, about 0.96 chance of at least one in a 5-card opener
• Dense interaction package with 10 hand traps and several hard negates
• Multiple Extra Deck beaters (Poseidra, Levia-Dragon, Abysstrite, Mermail Abyssgaios) give closing options

Weaknesses

• Illegal in OCG: two Forbidden cards are run
• No Side Deck, so no post-side adaptability
• Low archetype purity (15.3%); many off-archetype and generic slots dilute the engine
• No recorded boards, so the combo ceiling and median are unverified

Critical choke points

• Atlantean searcher and Umi-summon chain: if the opening starter is removed or negated, the deck has to rebuild from Mulcharmy draws
• Forbidden Bahamut Shark and Barrier Statue cannot be played as-is, so any line that depends on them fails in this format

Recommended changes

Evidence & confidence

• Verified: Deck is 57 Main / 15 Extra / 0 Side; Main is within 40-60 and Extra within 0-15; Bahamut Shark and Barrier Statue of the Torrent are Forbidden in OCG and are run 1 copy each; Ash Blossom and Dominus Impulse are Semi-Limited and run 2 copies, which is legal; Archetype core: 26 copies with inclusion 96% for Abysstrite as a typical core card
• Inferred: P(at least one core Atlantean card in a 5-card opener) about 0.96; Interaction density (10 hand traps, Solemn, Droll, Red Reboot, Daedalus Maelstrom) supports D7 and D8; Consistency and brick rate scores are text-based estimates
• Provisional: Meta Power is null because no dated metagame sample is supplied; D13 format fit is Provisional with no tournament link
• Data gaps: no combos supplied - combo floor/median/ceiling is 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, game-level, brick/starter/OTK rates) - those signals are Inferred or Unknown Meta Power is Provisional unless a dated metagame sample is supplied deck title is null; deck name is taken from archetype only no Side Deck, so post-side evaluation cannot be scored
