Atlantean Deck #565812 — Yu-Gi-Oh! TCG

Deck — Deck Power Evaluation

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

• Primary strategy: Midrange
• Secondary strategies: Toolbox, Control
• Format: tcg

Legality

Main 55 / Extra 15 / Side 0 — status: Illegal. 6 violation(s).

Identity & game plan

• Win condition: Mermail Xyz and Synchro beaters (Abyssgaios 2800, Abyssleed 2700, Abyssmegalo 2400 via Special Summon from hand) backed by Atlantean Dragoons direct attacks; Tidal, Dragon Ruler of Waterfalls and Mecha Phantom Beast Dracossack as late-game threats
• Turn 1 (going first): Open a WATER Mermail starter (Abyssteus, Abysspike, Abysslinde) to search a Level 4 or lower Mermail monster, then Xyz or Special Summon a board breaker
• Turn 2 (going second): Hand traps (D.D. Crow, Maxx "C", Debunk, Black Horn of Heaven) to disrupt the opponent's first summon, then rebuild through Mermail searchers
• Recovery: Recur WATER monsters from the Graveyard through Abyssteus, Abyssturge and Abyssgunde effects, and rebuild from Mermail searchers
• After siding: Not evaluable: the deck has zero Side Deck cards, so there is no post-side plan in the export

Why it scores here

This list is Illegal in TCG: six Forbidden copies (Maxx "C" x3, Soul Charge x3, Vanity's Emptiness x2) plus three Forbidden Extra Deck cards (Bahamut Shark, Abyss Dweller, Lavalval Chain) are in the deck, so the score below is a theoretical, structural-only read and is capped low. Structurally, the Mermail WATER engine with three-copy starters, 14 searcher-text cards (P(≥1 searcher in a 5-card opening) ≈ 0.78), and a 5-card hand-trap group (P(≥1 in a 6-card going-second hand) ≈ 0.45) give the deck a plausible midrange plan that can open functional hands fairly often. The deck is not a coherent Atlantean build: only 5 exact-name Atlantean cards (7.1% exact purity), with 65 off-archetype copies drawn from Mermail, Genex, Laval, Ghostrick and others, and only 3 of the 25 archetype-standard core cards present, so the archetype's own engine is largely absent. No recorded boards, tournament link, Side Deck, or win-rate data exist, so the ceiling and median scores are text-only inference. Popularity and archetype usage were not credited, and card scores were not averaged into the deck score.

Dimension scores

How the score was computed

Strategy profile: Midrange (primary) with Toolbox and Control context via modifiers; no profile weight blend applied. Structural ≈ 49, Going First ≈ 50, Going Second ≈ 45, Meta = provisional, Tournament Reliability ≈ 40. Modifiers: banlist exposure (-10); engine conflicts (-2). Final formula: Illegal: theoretical structural-only. 0.80*Structural(49) + 0.20*TournamentReliability(40) + ContextModifiers(-12) = 35 (Meta provisional)

Probability & combo summary

• Opening a starter: P(≥1) ≈ 0.78 · 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

• 14 searcher-text cards give high starter access (P ≈ 0.78 in a 5-card hand)
• Five hand traps and two floodgates offer interaction on both turns
• Multiple 2400+ ATK Mermail and Atlantean threats provide closing power

Weaknesses

• Illegal: six Forbidden copies and three Forbidden Extra Deck cards
• Low exact archetype purity (7.1%) and only 3 of 25 core cards present
• No Side Deck, so no post-side plan
• No recorded boards, so the median and ceiling are text-only inference

Critical choke points

• Mermail WATER starters (Abyssteus, Abysspike, Abysslinde) are the only real engine openers; no single missing starter is replaceable
• A 6-card going-second hand depends on one of 5 hand traps (P ≈ 0.45)

Recommended changes

Evidence & confidence

• Verified: Main Deck 55, Extra Deck 15, Side Deck 0; Six Forbidden copies and three Forbidden Extra Deck cards in the list; 14 searcher-text cards, 5 hand-trap cards; Exact archetype purity 7.1%, 3 of 25 core cards present
• Inferred: P(≥1 searcher in opening 5) ≈ 0.78 and archetype-core P ≈ 0.39; Going-first and going-second split estimates; Engine conflict and interaction quality from card text
• Provisional: Meta Power (no dated metagame sample); Matchup and format fit (D13)
• Data gaps: No combos supplied; combo floor, median and ceiling are text-only inference No tournament link; archetype meta-share and per-pilot record are absent No win-rate telemetry (going-first/second, matchup, brick and starter rates) Meta Power is Provisional unless a dated metagame sample is supplied Zero Side Deck cards in the export, so post-side plans cannot be evaluated
