Atlantean Deck #771052 — Yu-Gi-Oh! OCG

Deck — Deck Power Evaluation

Final Contextual Deck Power: 30/100 (±8 · Confidence: Low)

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

Legality

Main 56 / Extra 15 / Side 0 — status under the rules at evaluation time: Illegal. 3 violation(s).

Identity & game plan

• Win condition: Atlantean/Atlantis board pressure through Neptabyss, Atlantean Dragoons and Poseidra, converted by Extra Deck Link/Xyz/Synchro monsters (Inferred); Abysstrite and Poseidra Abyss Xyz boards, with Levia-Dragon and Azure Ocean Dragon Lord as Link bosses (Inferred)
• Turn 1 (going first): Open with searchers and Atlantis/Umi setup (Call of Atlantis, Advent of Atlantis, Atlantis City of the Sea Dragon) to reach a Link or Xyz boss, holding hand traps for the opponent's first activation (Inferred)
• Turn 2 (going second): Hold Ash Blossom, Ghost Ogre and Evenly Matched style interaction in the six-card hand to blank the opponent's board-building turn, then rebuild through GY-triggered searchers (Inferred)
• Recovery: GY-triggered searches (Neptabyss, Atlantean Dragoons, Warchief of Atlantis) and Mulcharmy draw effects refill the hand after a broken opening (Inferred)
• After siding: No Side Deck is registered, so there is no post-side plan; the deck cannot adapt between games (Verified: side_count 0)

Why it scores here

The score is built from the deck as a system and was not averaged from card scores. The 20-copy archetype core has a hypergeometric P(at least one in an opening 5) of about 0.90, and searchers recur across the list, so the engine should usually come online by turn 2 (Inferred). Interaction is the deck's strongest layer: nine hand traps, fourteen negation-text cards and sixteen removal-text cards support a Midrange/Stun plan that can blank a first board. Ceiling and median output cannot be measured, because no recorded boards exist, so combo dimensions stay low-confidence. Popularity did not earn points: the core is 45% present in this list and the deck has 22 distinct main-deck cards with a 12.7% exact-name Atlantean purity. The score is capped because the list is Illegal. Three Semi-Limited cards run three copies each, and the deck has no Side Deck, which removes any post-side plan.

Dimension scores

How the score was computed

Strategy profile: Midrange. Structural ≈ 52, Going First ≈ 55, Going Second ≈ 46, Meta = provisional, Tournament Reliability ≈ 45. Modifiers: banlist_exposure (-8); no_side_deck (-4); illegal_list_cap (-9). Final formula: Structural 52 → 0.80*52 + 0.20*45 ≈ 51 before modifiers; modifiers −12 → 39; capped at 30 because the list is Illegal (theoretical/structural only). Meta Power provisional (null).

Probability & combo summary

• Opening a starter: P(≥1) ≈ 0.9 · key two-card combo ≈ — · full-brick estimate ≈ 0.1 (all Inferred)
• Combo output: best PowerIndex —, median —, board-per-starter —
• Turn order: 0 going-first lines vs 0 going-second lines

Strengths

• Archetype core is near-certain to appear in the opening 5 (Inferred)
• Nine hand traps and sixteen removal-text cards give layered interaction (Verified text, Inferred quality)
• Broad Extra Deck coverage across Link, Xyz, Synchro and Fusion (Verified)

Weaknesses

• Illegal list: three cards exceed their Semi-Limited limit (Verified)
• No Side Deck, so no post-side adaptation (Verified)
• 22 distinct main-deck names with 12.7% exact Atlantean purity suggests an unfocused engine (Verified composition, Inferred)
• No recorded combos, so the ceiling and median are unmeasured (Verified data gap)

Critical choke points

• Atlantis, City of the Sea Dragon is a single copy that enables the Umi and Atlantis engine (Verified count)
• Searcher density depends on the Atlantean core remaining in the Deck (Inferred)

Recommended changes

Evidence & confidence

• Verified: Illegal status: three Semi-Limited cards at 3 copies each (limit 2); side_count 0; Main 56 / Extra 15 within OCG size rules; Card stats and text from the evidence pack
• Observed: No recorded combo boards exist (combos_evidence total_combos 0)
• Inferred: Opening-hand consistency P ≈ 0.90 for the archetype core; Hand-trap going-second estimate P ≈ 0.67; Engine routes and recovery plans from card text
• Provisional: Meta Power (null, no dated metagame sample); Matchup fit (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 (going-first/second, matchup, brick/starter rates) Meta Power is Provisional unless a dated metagame sample is supplied deck title is null
