Atlantean Deck #766106 — Yu-Gi-Oh! TCG

Deck — Deck Power Evaluation

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

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

Legality

Main 55 / Extra 15 / Side 0 — status: Illegal. 3 violation(s).

Identity & game plan

• Win condition: Atlantean and Abyss- board pressure: Poseidra, the Storming Atlantean and Atlantean Dragoons attacking, backed by Xyz and Synchro Extra Deck boards (Poseidra Abyss, Full Armored Dark Knight Lancer, Super Starslayer TY-PHON, Lancea); Hand-trap and negation interaction (Ash Blossom, Droll & Lock Bird, Ghost Ogre & Snow Rabbit, Solemn Warning, Solemn Judgment) protecting a single engine turn
• Turn 1 (going first): Open a WATER starter (Neptabyss, Mermail Abyssteus, Abysspike) to search or summon a Level 3 or 4 Atlantean or Mermail engine, then Xyz or Link into the Extra Deck
• Turn 2 (going second): Hold Ash Blossom, Droll, Solemn and Ghost Ogre to answer the opponent's first summon or activation, then convert the surviving hand into a board
• Recovery: Recover through GY-based searches and revivals (Abyssrhine, Mermail Abysspike, Atlantean Heavy Infantry) and Xyz material reuse, rather than through draw power
• After siding: Not evaluable: the export contains no side deck, so no post-side plan can be read

Why it scores here

The deck is Illegal in TCG as built: Ash Blossom & Joyous Spring and Dominus Impulse are each run three times against a Semi-Limited cap of two, so the score is a structural-only read capped at 30 and is not a normal final score. Structurally the list is coherent: 30 Atlantean-family core cards give a 98.5% chance of at least one core card in a five-card opening hand (hypergeometric, Inferred), and the engine has several independent WATER starters. Interaction is the strongest system trait, with seven hand traps and about 14 negation-text cards covering the first summon or activation of a turn. Closing power comes from Poseidra, the Storming Atlantean and Extra Deck 2800 to 3300 ATK boards, but no combo data exists, so the ceiling and median are text-based inferences. Popularity and archetype usage were not used to add points, and the card scores were not averaged into the deck score. The absence of a side deck and the lack of any matchup or meta data cap the deck's real-world reliability.

Dimension scores

How the score was computed

Strategy profile: Midrange. Structural ≈ 60, Going First ≈ 62, Going Second ≈ 60, Meta = provisional, Tournament Reliability ≈ 50. Modifiers: banlist_exposure (-6); no_side_deck (-3). Final formula: Illegal cap applied: structural-only theoretical read. Structural 60 + modifiers -9 = 49 (not used as final). Final = 0.80·Structural + 0.20·TournamentReliability would be 58; the Illegal rule caps the reported score at 30.

Probability & combo summary

• Opening a starter: P(≥1) ≈ 0.98 · 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

• Dense archetype core: 30 Atlantean-family copies give near-certain starter access
• Seven hand traps plus negation and removal text cover the first summon or activation of most turns
• Extra Deck carries 2800 to 3300 ATK boards across Xyz, Synchro and Link

Weaknesses

• Illegal copy counts for Ash Blossom and Dominus Impulse
• No Side Deck, so no post-side adaptation
• Only 18.6% exact-name archetype purity; many generic and off-archetype staples dilute the engine

Critical choke points

• Ash Blossom and Droll are the only answers to many going-second openings; legal reduction to two copies each weakens them
• Poseidra and the Abyss- Xyz line depend on a few WATER monsters in the GY or hand

Recommended changes

Evidence & confidence

• Verified: Main deck 55 and Extra deck 15 are within size rules for TCG; Ash Blossom & Joyous Spring and Dominus Impulse are each run 3 times against a Semi-Limited cap of 2; Composition counts: 8 Xyz, 4 Link, 3 Synchro in the Extra Deck; 27 distinct main-deck cards; Card stats and card text (ATK and DEF, levels, effect excerpts)
• Inferred: P(≥1 core card in opening hand) ≈ 0.985 (hypergeometric); Hand-trap and negation coverage of the first summon or activation of a turn; Poseidra and Full Armored Lancer boards reaching 2800 to 3300 ATK via Xyz and Link text reads
• Provisional: Meta Power; Matchup fit and format position (no tournament or meta data)
• Data gaps: No recorded combos supplied, so combo ceiling and median are text-only inference No tournament link: archetype meta-share and per-pilot match record absent No win-rate telemetry for brick, starter, going-first or matchup rates Meta Power provisional without a dated metagame sample Side deck is empty, so D12 and post-side plans cannot be evaluated
