Atlantean Deck #773284 — Yu-Gi-Oh! OCG

Deck — Deck Power Evaluation

Final Contextual Deck Power: 59/100 (±7 · Confidence: Medium)

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

Legality

Main 44 / Extra 14 / Side 0 — status: Legal.

Identity & game plan

• Win condition: Umi-engine boards: Abysstrite, Poseidra and Levia-Dragon Daedalus from the Extra Deck, backed by Atlantis, City of the Sea Dragon and Umi-named monsters; Atlantean Dragoons direct attacks for Level 3 or lower Sea Serpents, plus Link pressure from Neo-Daedalus Rage and S:P Little Knight
• Turn 1 (going first): Search and stack the Atlantis field and Umi starters (Neptabyss, Fish Sonar, Levia-Dragon, Warchief), then go to a Synchro, Xyz or Link board; Ghost Ogre and Droll are held for the opponent's turn
• Turn 2 (going second): Use the 6-card hand's hand traps (Ghost Ogre x3, Droll & Lock Bird) or Daedalus Maelstrom and Raigeki to break the opponent's board, then re-establish the Umi engine through Mulcharmy draws and GY recursion
• Recovery: Recover from the GY with Mermail Abysspike, Monster Arms of Atlantis, Warchief and LeVirtue Dragon's Virtue Stream, and rebuild the Atlantis field with Advent of Atlantis or Call of Atlantis
• After siding: None: the Side Deck is empty, so there is no sided plan; Side Deck adaptability is scored as a gap

Why it scores here

The deck is scored as one connected Umi/Atlantis system, not as an average of its card scores. Twenty searcher-text cards and three copies each of Neptabyss and Atlantean Dragoons give a high chance of a live starter in the opening hand (about 0.96 for at least one searcher in 5 cards, Inferred), which drives the consistency score. Interaction is the strongest area: four hand traps, Daedalus Maelstrom, Monster Arms, Virtue Stream, Call of Atlantis and Raigeki cover both going-first and going-second boards. Recorded combos are absent, so the combo ceiling and floor are text-only inferences and widen the band. The empty Side Deck and the absence of any tournament or win-rate data pull the score down; popularity (archetype usage stats) confirmed the list is real but earned no points on its own.

Dimension scores

How the score was computed

Strategy profile: Midrange. Structural ≈ 63.7, Going First ≈ 66, Going Second ≈ 62, Meta = provisional, Tournament Reliability ≈ 62. Modifiers: Empty Side Deck (-3); Restricted single-copy staples (-1). Final formula: 0.80*Structural + 0.20*TournamentReliability + ContextModifiers (Meta provisional; no dated metagame sample)

Probability & combo summary

• Opening a starter: P(≥1) ≈ 0.96 · 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 text (20 cards) makes a live starter in most opening hands
• Layered interaction on both turns: 4 hand traps, Maelstrom, Monster Arms, Virtue Stream, Call of Atlantis, Raigeki, Feather Duster
• Several independent recursion routes from the GY
• Coherent 14-card Extra Deck spanning Synchro, Xyz and Link with an Umi/Abyss core

Weaknesses

• Side Deck is empty, so there is no sided plan and no adaptation to matchups
• No recorded boards, so the combo ceiling and median are unverified
• Four single-copy restricted cards (Limited) each remove a copy of a role from the deck
• Many sub-archetype and Umi-name rules make it harder to pilot consistently

Critical choke points

• Umi-name and Atlantis field-zone conditions gate most Level and Link lines
• Single copies of Droll & Lock Bird and Harpie's Feather Duster are the only copies of those interaction roles
• Advent of Atlantis and Call of Atlantis are the main routes to the Atlantis field

Recommended changes

Evidence & confidence

• Verified: Legal in OCG with 44 Main, 14 Extra, 0 Side; no violations; Limited copies (Droll & Lock Bird, Harpie's Feather Duster, One for One, S:P Little Knight) are each run at 1 copy, within the legal limit; Composition counts (28 distinct Main, 14 Extra, copy histogram) match the card list; Searcher-text group 20 copies; hand-trap group 4 copies
• Observed: 33 usage-statistic rows exist for the Atlantean family
• Inferred: Starter consistency (about 0.96 for at least one searcher in 5 cards) from hypergeometric draw odds; Interaction layering and going-second hand-trap quality from card text; Recovery routes from card text and GY-recursion effects
• Provisional: Meta Power (no dated metagame sample); Matchup and format fit (no tournament link)
• Data gaps: no combos supplied; combo floor, median and ceiling are text-only inference (combos_evidence.total_combos = 0) no tournament link; archetype meta-share and per-pilot match record absent usage_statistics data issue: Abysstrite, Marincess Coral Anemone, LeVirtue Dragon, Mermail Abyssgaios, Poseidra Abyss, Mermail King - Neptabyss and Adamancipator Risen - Dragite are listed as in_this_deck=false, yet they appear in this deck's Extra Deck list; core_present_pct (58.3%) is therefore understated no win-rate telemetry (going-first/second, matchup, brick/starter rates); those are Inferred or Unknown Meta Power is Provisional unless a dated metagame sample is supplied Side Deck is empty, so post-side and sideboard adaptability cannot be assessed
