Atlantean Deck #765629 — Yu-Gi-Oh! TCG

Deck — Deck Power Evaluation

Final Contextual Deck Power: 31/100 (±8 · Confidence: Low)

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

Legality

Main 55 / Extra 15 / Side 0 — status under the rules at evaluation time: Illegal. 2 violation(s).

Identity & game plan

• Win condition: Atlantean/Abyss-Mermail XYZ and Synchro boards (Poseidra Abyss, Abysstrite, Lancea) built from WATER monsters, with Poseidra and Atlantean Dragoons as the attackers; Direct attacks from Atlantean Dragoons with Level 3 or lower Sea Serpents on board
• Turn 1 (going first): Open a Mermail or Atlantean starter (Neptabyss, Abyssrhine, Mermail Abyssteus) that searches a second WATER body, then extend to a Poseidra or Abyss XYZ
• Turn 2 (going second): Hold Ash Blossom, Ghost Ogre, Droll and Solemn cards to stop the opponent's summon, then rebuild the WATER engine from the GY
• Recovery: Mulcharmy and Mermail/Atlantean searchers refill the hand after a broken turn; recursion from the GY restarts the engine
• After siding: Not assessable: the deck has no side cards (side_count 0), so no post-side plan is evidenced

Why it scores here

This is a theoretical, structural-only read because the deck is Illegal: Ash Blossom and Dominus Impulse are each run three times against a Semi-Limited limit of two, and Called by the Grave, Gozen Match, Solemn Judgment and Triple Tactics Talent are Limited cards that are present. Within the list, the archetype core is reliably opened (about 98% of hands contain at least one of the 30 Atlantean/Mermail/Abyss core copies, Inferred), and the hand-trap and negation density gives the deck a credible interaction shell on the end board. The score is built from the whole system (engine access, interaction, recovery, closing boards), not from averaging card scores. Popularity does not count: the archetype usage stats confirm a real, accessible list, but they did not add points. There are no recorded combos, no tournament link and no side deck, so the combo, going-second and side-deck dimensions rest on structure and text and are held down. The illegal copy limits and banlist exposure cap the final score near 30.

Dimension scores

How the score was computed

Strategy profile: Midrange primary; Stun secondary treated as a context modifier, not a blend. Structural ≈ 54, Going First ≈ 55, Going Second ≈ 50, Meta = provisional, Tournament Reliability ≈ 40. Modifiers: illegal_copy_limit (-15); banlist_exposure (-5). Final formula: 0.80*Structural(54) + 0.20*TournamentReliability(40) = 51.2; Meta provisional; illegal-list modifiers -20 => 31 (theoretical, capped)

Probability & combo summary

• Opening a starter: P(≥1) ≈ 0.98 · key two-card combo ≈ — · full-brick estimate ≈ 0.02 (all Inferred)
• Combo output: best PowerIndex —, median —, board-per-starter —
• Turn order: 0 going-first lines vs 0 going-second lines

Strengths

• Core archetype access is high (about 98% of 5-card hands contain a core card, Inferred)
• Layered hand-trap and negation shell covering summons, activations and GY threats
• Multiple 3000+ ATK end-board options (Poseidra Abyss, Lancea) via flexible XYZ and Synchro routes

Weaknesses

• Illegal copy limits on two cards (Ash Blossom, Dominus Impulse) and four Limited cards
• No side deck, so there is no post-side adaptability
• Low archetype purity (18.6%) with 57 off-archetype copies weakens engine coherence
• No recorded combos, so the ceiling and median are unmeasured

Critical choke points

• Legal copy limits must be fixed before any normal score applies
• Poseidra and Abyss XYZ routes depend on a WATER-count threshold that the opponent can break with one hand trap

Recommended changes

Evidence & confidence

• Verified: Legality: Ash Blossom and Dominus Impulse exceed legal copies (3 vs 2, Semi-Limited); Main 55 and Extra 15 are inside the TCG size rules; Side 0 is allowed; Archetype purity 18.6% and 57 off-archetype copies from composition; Usage stats: 16 of 25 core cards present
• Observed: No recorded combo boards; the observed record is empty
• Inferred: Core access about 0.98 from hypergeometric odds; Interaction density and going-second hand-trap odds about 0.58; Midrange structure and Stun secondary from text roles and composition
• Provisional: Meta power and matchup fit (no dated metagame sample); Side-deck adaptability (no side cards)
• Data gaps: no combos supplied; combo floor, median and ceiling are text-only inference no tournament link; archetype meta-share and per-pilot record absent no win-rate telemetry; going-first/second, matchup and brick rates are Inferred or Unknown no side deck; post-side plan unassessable Meta Power is Provisional unless a dated metagame sample is supplied
