Atlantean Deck #770498 — Yu-Gi-Oh! TCG

Deck — Deck Power Evaluation

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

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

Legality

Main 59 / Extra 15 / Side 0 — status under the rules at evaluation time: Illegal. 5 violation(s).

Identity & game plan

• Win condition: Atlantean and Abyss- summon chains into Poseidra, the Storming Atlantean (2800 ATK) and Poseidra Abyss Xyz boss monsters, with Nibiru and Gameciel as additional big-body threats; Mermail Abyssgaios and Mermail King - Neptabyss end-board pressure after a successful Xyz or Link chain
• Turn 1 (going first): Open with Neptabyss, Abyssrhine or Mermail Abyssteus searchers to find a Level 3 or lower Sea Serpent or Atlantean starter, then build toward a Level 7 Synchro or Xyz boss
• Turn 2 (going second): Use Ash Blossom, Droll & Lock Bird, Evenly Matched, Dominus Impulse and Ghost Belle to disrupt the opponent's first board, then extend through Mulcharmy draw effects into Nibiru or Poseidra
• Recovery: Mermail and Atlantean graveyard effects plus Mulcharmy draw engines rebuild the hand; Deep Sea Minstrel and Gluttonous Reptolphin Greethys re-summon from the graveyard
• After siding: Not evaluable: the deck runs no Side Deck, so there is no post-side plan

Why it scores here

The deck reliably opens a searcher-driven Atlantean and Mermail starter: the 23 archetype-core copies give about a 92% chance of at least one core card in a 5-card opening hand, and the 15 searcher-text cards give about 78%. Its interaction density is high, with Ash Blossom, Evenly Matched, Dominus Impulse, Droll and Ghost Belle covering both hand-trap and on-field disruption, which is why D7 is the strongest dimension. Conversion and median output are weaker: no recorded boards exist, so the combo floor and ceiling are text-only inferences, and the 17.6% exact-archetype purity shows the list stacks several sub-archetypes (Abyss-, Mermail, Mulcharmy, Artifact, Kaiju, Marincess) rather than one coherent engine. The score was NOT produced by Atlantean's popularity or by averaging card scores; because the deck is Illegal (five copy-limit or Forbidden violations) it is capped at 30 and labelled structural-only.

Dimension scores

How the score was computed

Strategy profile: Midrange. Structural ≈ 54.7, Going First ≈ 52, Going Second ≈ 58, Meta = provisional, Tournament Reliability ≈ 42. Modifiers: banlist exposure (-8); no side deck (-2); illegal cap (-12). Final formula: Illegal cap: uncapped 0.80*54.7 + 0.20*42 + modifiers (-10) = 42; capped to 30 because the deck is Illegal. Theoretical/structural only. Meta Power provisional (null).

Probability & combo summary

• Opening a starter: P(≥1) ≈ 0.92 · key two-card combo ≈ — · full-brick estimate ≈ 0.08 (all Inferred)
• Combo output: best PowerIndex —, median —, board-per-starter —
• Turn order: 0 going-first lines vs 0 going-second lines

Strengths

• Redundant searcher and starter suite across Neptabyss, Abyssrhine, Mermail Abyssteus and Abysspike
• High interaction density with hand traps and on-field negation and removal, including Ash Blossom, Evenly Matched and Droll
• Strong 2800 to 3000 ATK boss monsters (Poseidra x3, Nibiru, Poseidra Abyss, Coelacanth)

Weaknesses

• Illegal list: five copy-limit or Forbidden violations, so the deck cannot be played as built
• Low exact-archetype purity (17.6%) across several sub-archetypes weakens engine coherence
• No Side Deck, leaving no post-side adaptation
• Several situational hand traps and off-theme 3-copy staples create dead-hand risk

Critical choke points

• Dependence on a Level 3 or lower Sea Serpent or Atlantean starter to open the Poseidra line
• Forbidden Trishula and Called by the Grave add no legal value and occupy slots in the list

Recommended changes

Evidence & confidence

• Verified: Deck is Illegal with five copy-limit and Forbidden violations; Main 59 and Extra 15 are within size rules; Exact-archetype purity is 17.6%; Side deck is empty (side_count 0); Card stats and text are read from the evidence pack
• Inferred: Archetype-core opening probability 0.92 and searcher group 0.78; Going-second hand-trap coverage 0.84 for a 6-card hand; Interaction density is high from card-text flags; Boss monsters and closing power from stats and text
• Provisional: Meta power is null: no dated metagame sample; Matchup fit (D13) is a neutral placeholder; Tournament reliability is estimated without tournament data
• 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 absent No win-rate telemetry (going-first or going-second, matchup, brick or starter rates) Usage statistics mark Abysstrite and LeVirtue Dragon as not in deck, but the cards list includes both in the Extra Deck; the inconsistency is unresolved No side deck, so post-side performance cannot be assessed Meta Power is Provisional unless a dated metagame sample is supplied
