Atlantean Deck #767855 — Yu-Gi-Oh! OCG

Deck — Deck Power Evaluation

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

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

Legality

Main 59 / Extra 15 / Side 0 — status under the rules at evaluation time: Illegal. 2 violation(s).

Identity & game plan

• Win condition: Atlantean and Abyss-/Mermail/Daedalus Extra Deck boards (Poseidra, Levia-Dragon, Neptabyss lines) overwhelming the opponent with 2000-3000 ATK monsters after a hand-trap-protected starter; Direct attacks from Atlantean Dragoons while Level 3 or lower Sea Serpent monsters are on the field
• Turn 1 (going first): Open a Neptabyss, Abyssrhine, or Mulcharmy starter, search through Atlantean/Mermail effects into Atlantis, City of the Sea Dragon or Levia-Dragon lines; hold Ash Blossom, Droll and Solemn for the opponent's first activation
• Turn 2 (going second): Use Ash Blossom, Dominus Impulse, Solemn Strike/Judgment/Warning, Droll and Evenly Matched to slow the opponent's first summon, then convert the surviving starter into a Extra Deck board
• Recovery: Recover from GY through Warchief, Mermail Abysspike and Abyss-sting Triaina effects that add or Special Summon Atlantean/Mermail monsters, plus Mulcharmy draw effects to rebuild the hand
• After siding: Not evaluable: the deck list has zero Side Deck cards, so no post-side plan exists in the evidence

Why it scores here

The deck is scored as a system, not an average of its 59 main and 15 extra cards. Its engine is reasonably accessible: the archetype-core group has an estimated 0.885 chance of at least one hit in a 5-card opening hand, though this is a proxy and not a combo-verified starter rate (Inferred). Its interaction density is the strongest signal, with 6 hand traps, 15 negation-text cards and 20 removal-text cards giving it a credible way to answer the opponent's first play (Inferred semantic read). Conversion and median output cannot be verified because the evidence contains zero recorded boards, so the ceiling and floor scores rest on text alone and are capped near the middle of the scale. The list is Illegal: Ash Blossom and Dominus Impulse each run 3 copies against a limit of 2, and the deck omits Abysstrite, the single most-used core card at 100 percent archetype inclusion, which lowers confidence in its engine identity. Popularity and usage statistics confirm the list is a real Atlantean build and do not raise the score; the illegal cap sets the final value.

Dimension scores

How the score was computed

Strategy profile: Midrange. Structural ≈ 55, Going First ≈ 55, Going Second ≈ 62, Meta = provisional, Tournament Reliability ≈ 48. Modifiers: banlist_exposure_over_limit (-8); no_combo_corpus (-4); illegal_cap (-6). Final formula: 0.80*Structural(55) + 0.20*TournamentReliability(48) = 53.6, plus modifiers -12 = 41.6; Illegal legality cap applied, final set to 35 (theoretical/structural only, not a normal Final)

Probability & combo summary

• Opening a starter: P(≥1) ≈ 0.89 · 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 hand-trap and negation coverage (6 hand traps, 15 negation-text cards)
• Multiple independent starters and recovery routes
• High-ATK Extra Deck threats (Poseidra 2800, Levia-Dragon 2600, Poseidra Abyss 3000)

Weaknesses

• Illegal copy counts on Ash Blossom and Dominus Impulse
• Side Deck empty, so no post-side adaptability
• Low exact-name purity (16.2%) and 59 main cards reduce compactness
• Missing Abysstrite, the highest-usage core card

Critical choke points

• Over-limit hand traps must be cut to legal copies before the list can be played
• Starter must survive the first opponent interaction; no secondary board breaker is evidenced

Recommended changes

Evidence & confidence

• Verified: Main 59 / Extra 15 / Side 0 counts and size rules (40-60, 0-15, 0-15); Copy-limit violations: Ash Blossom (3 vs 2) and Dominus Impulse (3 vs 2); Limited cards each run at 1 copy: Droll, Instant Fusion, One for One, Solemn Judgment; Archetype usage: 13 of 20 core cards present; Abysstrite (100%) missing; Side Deck count is 0
• Inferred: Starter access estimate 0.885 (archetype-core proxy); Interaction density read from card text (hand traps, negation, removal); Ceiling and median scores estimated from card text only (no recorded boards); Going-second strength from hand-trap density; Pilot complexity from decision-point count
• Provisional: Meta Power (null, no dated metagame sample); Matchup and format fit (no tournament data)
• Data gaps: no combos supplied: combo floor/median/ceiling is text-only inference no tournament link: archetype meta-share and per-pilot match record absent no win-rate telemetry (going-first/second, matchup, brick/starter rates) Meta Power provisional unless a dated metagame sample is supplied Side Deck is empty, so post-side performance cannot be assessed Deck title is null in the export
