Atlantean Deck #774051 — Yu-Gi-Oh! TCG

Deck — Deck Power Evaluation

Final Contextual Deck Power: 35/100 (±10 · Confidence: Low)

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

Legality

Main 57 / Extra 15 / Side 0 — status under the rules at evaluation time: Illegal. 3 violation(s).

Identity & game plan

• Win condition: Atlantis / Umi field-driven Extra Deck boards (Levia-Dragon of Atlantis - Daedalus, Azure Ocean Dragon Lord - Neo-Daedalus Rage, Poseidra) built from a WATER-heavy main deck; Atlantean and Mermail beatdown through Atlantean Dragoons direct attacks and Poseidra's 2800 ATK body
• Turn 1 (going first): Search and summon through Penguin, Neptabyss, Mermail Abyssteus, and Mulcharmy Purulia to build toward an Atlantis field and Extra Deck boards; hold Ash Blossom and Ghost Ogre for the opponent's first effect
• Turn 2 (going second): Use the six-card hand to hold Ash Blossom, Droll and Lock Bird, Ghost Ogre and Dominus Impulse as interaction, then convert through Mulcharmy draw and a single Extra Deck summon
• Recovery: Revive Atlantis-mentioning monsters from the GY through Warchief of Atlantis, Monster Arms of Atlantis and Siren Vortex; recover searcher count through Mermail and Atlantean searchers
• After siding: Not evaluable: the deck has no Side Deck, so no post-side plan exists in the evidence

Why it scores here

The deck reliably opens a searcher-driven hand: P(at least one searcher-text card in a 5-card opening hand) is about 0.88, and the archetype-core group is almost always present, so the engine is accessible on turn one (Inferred from hypergeometric estimates). Interaction is the strongest system trait, with 6 hand traps, 13 negation-text cards and 18 removal-text cards giving layered answers that survive a single disruption. Conversion is the weak link: no recorded boards exist, so the ceiling and median are text-only inference and are scored conservatively. The main deck runs five unrelated sub-engines (Atlantis/Umi, Abyss, Mermail, Daedalus, Deep Sea) plus Adamancipator, Graydle, Icejade and Marincess Extra Deck cards, with only 18 percent exact-name archetype purity, which lowers consistency and pilotability. The deck is Illegal as submitted (two cards over their Semi-Limited copy limit) and has no Side Deck, so the score is capped and reported as theoretical and structural only; popularity and archetype usage were not credited, and card scores were not averaged.

Dimension scores

How the score was computed

Strategy profile: Midrange. Structural ≈ 56, Going First ≈ 52, Going Second ≈ 58, Meta = provisional, Tournament Reliability ≈ 50. Modifiers: Banlist exposure (-4); Engine conflicts (-4); No side deck (-4). Final formula: Uncapped: 0.80*Structural(55.6) + 0.20*TournamentReliability(50) + Modifiers(-12) = 42.5; Illegal cap applied -> reported 35 as theoretical/structural-only; Meta Power provisional (null)

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

• Searcher density gives an accessible opening hand (Inferred from hypergeometric estimate)
• Layered interaction: 6 hand traps, 13 negation-text and 18 removal-text cards
• Recursion through Atlantis-mentioning monsters supports later turns

Weaknesses

• Illegal as submitted: two cards over their Semi-Limited copy limit
• No Side Deck, so best-of-3 adaptability is zero
• Five competing sub-engines reduce coherence and brick resilience
• No combo evidence, so conversion and median output are unverified

Critical choke points

• Atlantis, City of the Sea Dragon on the field is required for several Umi and Extra Deck lines (Inferred)
• Going-second plans depend on the six-card hand containing at least one hand trap (P ≈ 0.50 for at least one of 6 hand traps; Inferred)

Recommended changes

Evidence & confidence

• Verified: Deck is Illegal: Ash Blossom and Dominus Impulse each run 3 copies against 2 legal; Main 57 and Extra 15 are within size rules; Side 0 is within the 0 to 15 range; Archetype exact-name purity 18.1 percent
• Observed: Usage stats: Atlantean core cards present, 15 of 25 core cards included
• Inferred: Searcher access: P(at least one searcher-text card in hand5) ≈ 0.88; Interaction layering from hand-trap and negation text; Going-second hand-trap coverage ≈ 0.50
• Provisional: Meta Power (no dated meta sample); Matchup and format fit (D13)
• Data gaps: no combos supplied, so combo floor, median and ceiling are text-only inference no tournament link, so archetype meta-share and per-pilot match record are absent no win-rate telemetry exists for going-first, going-second, matchup or brick rates Side Deck is empty, so post-side performance cannot be evaluated Meta Power is provisional unless a dated metagame sample is supplied
