Atlantean Deck #648043 — Yu-Gi-Oh! TCG

Deck — Deck Power Evaluation

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

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

Legality

Main 55 / Extra 15 / Side 0 — status under the rules at evaluation time: Illegal. 5 violation(s).

Identity & game plan

• Win condition: Extra Deck boards from Synchro, Xyz and Link summons (Poseidra, Abyssgaios, Graydle Dragon, Swordsoul Chengying) that pressure with 2800 to 3000 ATK bodies; Atlantean and Mermail recursion and searches that feed repeated Extra Deck summons over several turns
• Turn 1 (going first): Open on Atlantean or Mermail searchers (Neptabyss, Mermail Abyssteus, Abysspike, First Penguin) and convert the searched starter into a Synchro, Xyz or Link board
• Turn 2 (going second): Hold Ash Blossom, Droll & Lock Bird and Dominus Impulse to slow the opponent's first extension, then rebuild the board from the GY with the Atlantean and Mermail effects
• Recovery: Mermail and Atlantean GY-triggered effects and Mulcharmy draw effects refill the hand after interaction is spent
• After siding: Not evaluable: the side deck is empty, so no post-side plan exists in the export

Why it scores here

The deck's engine is reliably accessible: the archetype core group has a 0.9991 chance of at least one copy in a 5-card opening hand, and the 17 searcher-text cards give about 0.86 odds of a search in the opening hand (Inferred, hypergeometric). Its ceiling comes from Extra Deck boss monsters with 2800 to 3000 ATK and several negation and removal effects, but no recorded boards exist, so combo conversion and median output are text-based inferences. The score was not produced by averaging card scores, and popularity did not earn points: the archetype usage data only confirms the core list is real. The deck is Illegal: five cards exceed their copy or ban limits, two of them Forbidden, so the score is capped and labelled structural-only. With no side deck and no dated meta sample, post-side and matchup dimensions are provisional.

Dimension scores

How the score was computed

Strategy profile: Midrange. Structural ≈ 59, Going First ≈ 58, Going Second ≈ 56, Meta = provisional, Tournament Reliability ≈ 50. Modifiers: Illegal copy-limit and Forbidden exposure (-8); Empty side deck (-4). Final formula: Unclamped: 0.80*Structural(58.8) + 0.20*TournamentReliability(50) + modifiers(-12) = 45. Capped to 35 because the deck is Illegal; the result is theoretical/structural-only. Meta Power is provisional.

Probability & combo summary

• Opening a starter: P(≥1) ≈ 1 · 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

• Very high starter access: archetype core present in 99.9% of opening hands (Inferred)
• Layered interaction: Ash Blossom, Droll & Lock Bird, Dominus Impulse, Called by the Grave and Evenly Matched (Verified card text)
• High-ATK Extra Deck bosses (Poseidra, Abyss Xyz, Graydle Dragon, Chengying) give closing power (Verified card stats)

Weaknesses

• Illegal as built: five copy-limit or ban violations, two of them Forbidden
• Empty Side Deck: no post-side adaptation
• Low Atlantean exact-name purity (18.6%): the engine is spread across several sub-archetypes

Critical choke points

• Forbidden Trishula and Called by the Grave cannot be legally run, so any line that depends on them must be replaced
• Droll & Lock Bird, Ash Blossom and Dominus Impulse are over their limits, so the interaction suite is not legally reproducible at current counts

Recommended changes

Evidence & confidence

• Verified: Main Deck is 55 cards and Extra Deck is 15, both within format size rules; Five copy-limit or ban violations in the export; Card text and stats for the listed cards
• Inferred: Core-starter access of 0.9991 and searcher access of 0.8557 from hypergeometric estimates; Ceiling and interaction quality inferred from card text without recorded boards
• Provisional: Meta Power is null; matchup and format-fit scores have no dated sample; Post-side plan cannot be assessed without a side deck
• Data gaps: No combos supplied; combo floor, median and ceiling are text-only inference No tournament link; archetype meta-share and per-pilot match record are absent No win-rate telemetry for going-first, going-second, matchup or brick rates Side deck is empty, so post-side adaptability is unmeasured Meta Power is provisional without a dated metagame sample
