Atlantean Deck #770257 — Yu-Gi-Oh! OCG

Deck — Deck Power Evaluation

Final Contextual Deck Power: 41/100 (±10 · Confidence: Low)

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

Legality

Main 40 / Extra 15 / Side 0 — status: Illegal. 1 violation(s).

Identity & game plan

• Win condition: Umi/Atlantis board pressure converted through Link and Xyz bosses (Azure Ocean Dragon Lord - Neo-Daedalus Rage, Poseidra, Levia-Dragon - Daedalus); Atlantean Dragoons and Sea Serpent direct attacks, plus Levia-Dragoon and Poseidra ATK pressure
• Turn 1 (going first): Advent of Atlantis, Call of Atlantis or Fish Sonar to fetch Atlantis/Umi monsters, then Neptabyss and Warchief to build Umi and reach a Link or Xyz boss
• Turn 2 (going second): Use Ash Blossom, Maxx C, Droll & Lock Bird and Infinite Impermanence to disrupt the opponent's first summon, then rebuild through searchers and GY recursion
• Recovery: Warchief of Atlantis and Neptabyss recur from the GY; Mulcharmy Purulia draws when the hand is emptied
• After siding: Not applicable: the deck has no Side Deck, so there is no post-side plan.

Why it scores here

The deck reliably opens a searcher-dense starter set, since the searcher group reaches at least one copy in the opening 5 about 95% of the time (Inferred). Its interaction package of six hand traps and roughly ten negation or removal texts gives it real layered disruption, which is what most of the score rests on. Conversion into a board is credible through the Umi and Link or Xyz boss lines, but no recorded boards exist, so the ceiling and median are text-only inferences and are scored conservatively. The list is Forbidden-illegal (two Bahamut Shark), so it is capped and evaluated as structural only, and it has no Side Deck, which holds the post-side score near zero. Popularity was not credited and card scores were not averaged; the score reflects the deck as a system.

Dimension scores

How the score was computed

Strategy profile: Midrange. Structural ≈ 54, Going First ≈ 55, Going Second ≈ 52, Meta = provisional, Tournament Reliability ≈ 48. Modifiers: banlist_exposure_illegal_cap (-12). Final formula: 0.80*Structural(54.2) + 0.20*TournamentReliability(48) + Illegal cap(-12) = 41 (Meta provisional)

Probability & combo summary

• Opening a starter: P(≥1) ≈ 0.95 · 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 searcher and starter access (17 searcher-text cards)
• Six hand traps plus multiple negation and removal texts for layered interaction
• Link 4 and Xyz boss options with recursion lines

Weaknesses

• Two Forbidden Bahamut Shark make the list illegal in OCG
• No Side Deck, so no post-side plan
• Low archetype purity (9.1% exact name) and several sub-archetype conflicts

Critical choke points

• Umi must be on the field for most boss and negation lines; losing it stalls the engine
• Atlantis, City of the Sea Dragon is a single copy and the Field Zone access point

Recommended changes

Evidence & confidence

• Verified: Illegal status: 2 Forbidden Bahamut Shark (0 legal copies); Main 40, Extra 15, Side 0 counts and copy-limit check; Card text for the searcher, hand trap and negation roles
• Observed: Searcher-group draw probability from the hypergeometric table
• Inferred: Engine accessibility and brick estimates; Interaction quality from text roles; Going-first and going-second splits; Pilotability and resource estimates
• Provisional: Meta power (null) and matchup fit; Median and ceiling combo output (no recorded boards); Post-side plan (no Side Deck)
• Data gaps: No combos supplied, so combo floor, median and ceiling are text-only inference No tournament link, so archetype meta-share and pilot record are absent No win-rate telemetry (going-first/second, matchup, brick rate) Meta Power is Provisional without a dated metagame sample No Side Deck, so post-side performance cannot be assessed
