Atlantean Deck #774756 — Yu-Gi-Oh! OCG

Deck — Deck Power Evaluation

Final Contextual Deck Power: 40/100 (±10 · Confidence: Low)

• Primary strategy: Midrange
• Secondary strategies: Tempo, 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: Board pressure from Atlantean/Mermail WATER summons into large Synchro, Xyz and Link boards (Poseidra, Levia-Dragon, Moulinglacia, Mermail Abyssgaios).; Direct attacks from Atlantean Dragoons and Level 3 or lower Sea Serpents, and Atlantis-field Umi Link boards.
• Turn 1 (going first): Open a searcher such as Neptabyss, Mermail Abyssteus or First Penguin, convert into a Level 7 or 8 WATER boss, and keep Ash Blossom or Ghost Ogre up for the response.
• Turn 2 (going second): Hold Ash Blossom, Ghost Ogre, Nibiru or Droll & Lock Bird to answer the opponent's first summons, then rebuild through GY-triggered WATER effects.
• Recovery: Recover from the GY through Mermail Abyssteus, Atlantean Heavy Infantry, Deep Sea Minstrel and Warchief of Atlantis; search with Neptabyss and Call of Atlantis.
• After siding: Not evaluable: no Side Deck was supplied (side_count 0).

Why it scores here

The deck reliably opens a searcher on the first hand: P(at least one searcher-text card in a 5-card opening hand) is about 0.88 and the archetype core is about 0.97 (Inferred, hypergeometric). Its engine converts into WATER Level 7 and 8 bosses and a wide set of Synchro, Xyz and Link extra-deck options. Hand traps (9 cards, about 0.66 chance of at least one in a going-second 6-card hand) and roughly 13 negation-text cards give it layered interaction. Score is capped low because the list is illegal: Ash Blossom and Dominus Impulse each run 3 copies against a limit of 2. No combos, tournament results or side deck were supplied, so the combo floor, median and side-deck scores are text-only inferences. The score comes from the system's consistency, interaction and recovery, not from averaging card scores and not from the archetype's popularity; 9 of 24 usage-core cards are absent, including Abysstrite and Marincess Coral Anemone.

Dimension scores

How the score was computed

Strategy profile: Midrange primary, no secondary blend applied. Structural ≈ 54, Going First ≈ 55, Going Second ≈ 50, Meta = provisional, Tournament Reliability ≈ 45. Modifiers: Banlist exposure (-10); No side deck (-2). Final formula: 0.80*Structural + 0.20*TournamentReliability (Meta provisional); illegal-deck cap applied: theoretical/structural-only

Probability & combo summary

• Opening a starter: P(≥1) ≈ 0.88 · 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

• Consistent searcher access (about 0.88 at hand 5) across several WATER searchers
• Nine hand traps and about 13 negation-text cards give layered interaction
• Strong WATER boss options at 2600 to 3000 ATK across Synchro, Xyz and Link

Weaknesses

• Illegal in OCG: two cards exceed their Semi-Limited limit
• Heavy duplication of Atlantean and Mermail monsters
• No side deck, no combo data, and nine usage-core cards missing

Critical choke points

• Atlantis, City of the Sea Dragon and Umi-field conditions gate several Daedalus and Atlantis effects
• Multiple GY-triggered WATER effects depend on a populated graveyard

Recommended changes

Evidence & confidence

• Verified: Illegal status: Ash Blossom & Joyous Spring and Dominus Impulse each over their Semi-Limited limit of 2; Main 57 and Extra 15, within OCG size rules; Card stats and text for every listed card; Usage core: 15 of 24 cards present (62.5%)
• Inferred: Searcher access about 0.88 at hand 5; Hand-trap presence about 0.66 at hand 6 going second; Going-first and going-second scores from text and probability only; Interaction and recovery quality from text roles
• Provisional: Meta Power (no dated metagame sample); Matchup and format fit (no tournament link); Side-deck adaptability (no side deck supplied)
• 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 side deck supplied: post-side plan unscored No win-rate telemetry exists in YGOVN Meta Power provisional without a dated metagame sample
