Atlantean Deck #771786 — Yu-Gi-Oh! OCG

Deck — Deck Power Evaluation

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

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

Legality

Main 47 / Extra 18 / Side 0 — status under the rules at evaluation time: Illegal. 3 violation(s).

Identity & game plan

• Win condition: Extra Deck end boards built from Atlantis/Umi/Daedalus/Abyss pieces (Poseidra Abyss, Abysstrite, Levia-Dragoon - Daedalus, Azure Ocean Dragon Lord) pressuring with 2600-3000 ATK bodies; Synchro and Xyz beatsticks (White Aura Whale, Icejade Gymir Aegirine, Brionac) once the board is established
• Turn 1 (going first): Open a Penguin, Neptabyss, Mulcharmy Purulia or Warchief starter, search through Atlantis/Umi text, and build toward Link or Xyz plays; hand traps held for the opponent's first activation
• Turn 2 (going second): Use Ash Blossom, Maxx C, Droll & Lock Bird and Dominus Impulse to slow the opponent's first Summon, then convert the search chain into a Link or Xyz board
• Recovery: Recur First Penguin, Warchief and Monster Arms of Atlantis from the GY; Fish Sonar and Call of Atlantis supply replacement Umi/Atlantis pieces
• After siding: Not evaluable: the deck has no Side Deck, so there is no post-side plan

Why it scores here

The list is Illegal in OCG (two Forbidden cards and an 18-card Extra Deck against a 15-card cap), so it is scored structurally only and the final score is capped at 35. The deck opens reliably: the four searcher-engine starters (Neptabyss, Mulcharmy Purulia, First Penguin, Warchief) are each about 29% to appear in a 5-card opening hand and roughly 92% at least one searcher is present in the hand. Interaction is the strongest system feature, with four hand traps, Dominus Impulse, Daedalus Maelstrom and Ice Barrier giving layered answers, and its end boards reach 2600–3000 ATK. The score is not driven by the Atlantean archetype's popularity, which is only a usage-stat signal, and the card scores were not averaged. No recorded boards, tournament record or side deck exist, so the conversion, median and matchup dimensions remain Inferred or Provisional, and the 12.3% exact-name archetype purity means the engine coherence is also an inference.

Dimension scores

How the score was computed

Strategy profile: 0.85 Midrange + 0.15 Toolbox (dimension weights shown below). Structural ≈ 56.6, Going First ≈ 55, Going Second ≈ 58, Meta = provisional, Tournament Reliability ≈ 45. Modifiers: banlist exposure (-8); extra deck over limit (-4); illegal legality cap (0). Final formula: No reliable metagame: 0.80*Structural(56.6) + 0.20*TournamentReliability(45) = 54.3; plus modifiers (-12) = 42.3; capped at 35 because legality is Illegal (theoretical/structural-only)

Probability & combo summary

• Opening a starter: P(≥1) ≈ 0.29 · 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

• Four searcher-engine starters at 3 copies each give a high chance of an opening engine (Verified probability, Inferred consistency)
• Layered interaction: hand traps, Dominus Impulse, Ice Barrier and Daedalus Maelstrom cover multiple phases
• Several independent engines (Atlantis field, Daedalus Link, Abyss Xyz) keep the plan going after one is answered

Weaknesses

• Illegal in OCG: two Forbidden cards and an 18-card Extra Deck
• Low archetype purity (12.3% exact name) suggests a loosely unified engine
• No Side Deck, so no post-side adaptability

Critical choke points

• Atlantis, City of the Sea Dragon and Umi-related field effects are the connective tissue of most lines; losing the field card breaks several engines
• The Extra Deck is over the cap, so the deck cannot be registered as built

Recommended changes

Evidence & confidence

• Verified: Illegal status: Barrier Statue of the Torrent and Bahamut Shark are Forbidden in OCG (1 copy each); Extra Deck is 18 cards against an OCG maximum of 15; Main Deck is 47 cards, within the 40–60 range; Searcher-text group P(≥1 in 5-card hand) ≈ 0.92; Starter 3-copy P(≥1 in 5-card hand) ≈ 0.29
• Observed: Archetype usage statistics show Abysstrite, Neptabyss and Mulcharmy Purulia as frequently included core cards (usage context only)
• Inferred: Multi-engine consistency and interaction layering estimated from card text; Interaction quality (D7) and resilience (D5) scored from card text and role tags; Going-first and going-second scores are structural estimates
• Provisional: Meta Power is null; matchup fit (D13) is provisional without a dated metagame sample; Tournament reliability is provisional because no tournament record exists
• Data gaps: No combos supplied; combo floor, median and ceiling are text-only inference No tournament link; archetype meta-share and per-pilot match record absent No win-rate telemetry; going-first/second, matchup and brick rates are Inferred or Unknown Meta Power is Provisional unless a dated metagame sample is supplied No Side Deck, so post-side performance is unmeasurable
