Umi Deck #772105 — Yu-Gi-Oh! OCG

Deck — Deck Power Evaluation

Final Contextual Deck Power: 30/100 (±10 · Confidence: Low)

• Primary strategy: Combo
• Secondary strategies: Stun
• Format: ocg

Legality

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

Identity & game plan

• Win condition: Umi / Atlantis board into Daedalus Link and Azure Ocean Dragon Lord - Neo-Daedalus Rage (2900 ATK) with Warchief and Siren Vortex recursion; Fusion and Synchro boss follow-up (The Dragon that Devours the Dogma, Ecclesia and the Dark Dragon, Brionac) when the Link line is stopped
• Turn 1 (going first): Open Atlantis-family starters (Siren Vortex, Warchief, Advent of Atlantis) with First Penguin and Mulcharmy draws, then extend into Daedalus Link (Inferred from card text; no recorded boards)
• Turn 2 (going second): Six-card hand with Ash Blossom, Ghost Ogre, Infinite Impermanence and Dominus Impulse to strip the opponent's board, then rebuild Umi (Inferred)
• Recovery: Warchief and Siren Vortex recursion from GY, plus Advent of Atlantis and Monster Arms of Atlantis resetting the field (Inferred)
• After siding: None: side deck is empty, so there is no post-side plan

Why it scores here

This deck is scored on its system, not by averaging its card scores. Its consistency is limited: the Atlantis starters are three copies each or fewer, the P(at least one starter in opening 5) is about 0.25 per 3-copy card, and 21 distinct main-deck cards with 70 off-archetype copies (Mulcharmy, Penguin, Forbidden, Solemn, Branded, Dominus) dilute the engine. Interaction is the strongest part of the list (12 hand traps, 20 negation-text and 21 removal-text cards), which lifts the going-second and end-board scores. No recorded boards exist, so combo ceiling and median are text-only inferences. The deck is Illegal: five cards exceed the OCG Semi-Limited limit of 2, so the uncapped contextual score of about 37 is reduced to 30 and the result is structural-only. Archetype popularity (Umi usage stats) confirms the list is real but earned no points, and there is no side deck and no meta sample.

Dimension scores

How the score was computed

Strategy profile: Combo. Structural ≈ 51, Going First ≈ 48, Going Second ≈ 58, Meta = provisional, Tournament Reliability ≈ 42. Modifiers: banlist_exposure (-6); engine_conflicts (-3); no_side_deck (-3). Final formula: Uncapped: 0.80*Structural(51) + 0.20*TournamentReliability(42) + ContextModifiers(-12) = 37. Legality cap (Illegal, 5 copy-limit violations) reduces the reported score to 30. Meta Power is null (Provisional). Structural-only evaluation.

Probability & combo summary

• Opening a starter: P(≥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

• High interaction density: 12 hand traps and about 20 negation-text cards for going second
• Recursive Atlantis engine (Warchief, Siren Vortex, Advent of Atlantis) gives some resource regeneration
• Strong link and boss options at 2900 and 2600 ATK (Neo-Daedalus Rage, Levia-Dragon Daedalus)

Weaknesses

• Illegal list: five Semi-Limited cards run 3 copies against a limit of 2
• Low starter density (about 0.25 per 3-copy starter in opening 5) and high off-archetype dilution
• No side deck and no recorded boards, so the combo ceiling and median cannot be verified

Critical choke points

• Access to the Atlantis field and Daedalus Link line depends on 1-2 copies of key starters
• Hand-trap cost of 2000 LP (Solemn Warning) and the negation timing for going second

Recommended changes

Evidence & confidence

• Verified: Illegal status: five Semi-Limited cards at 3 copies against a limit of 2; Main 55, Extra 15, Side 0 (main within 40-60); Archetype spread: 70 off-archetype copies, 0% exact-name purity; Role counts: 12 hand traps, 21 tech, 20 negation-text, 21 removal-text
• Observed: Archetype usage stats: 16-card core, 7 core cards present (43.8%)
• Inferred: Starter P(at least 1) in opening 5 is about 0.25 per 3-copy card; Going-second interaction package strength from card text; Umi plan lines and recovery routes from card text
• Provisional: Meta power and matchup fit (no dated metagame sample or tournament link)
• 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 for going-first, going-second, matchup, or starter/brick rates Meta Power is Provisional without a dated metagame sample Side deck is empty, so post-side performance cannot be assessed
