Umi Deck #764359 — Yu-Gi-Oh! OCG

Deck — Deck Power Evaluation

Final Contextual Deck Power: 25/100 (±10 · Confidence: Low)

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

Legality

Main 44 / Extra 13 / Side 0 — status: Illegal. 2 violation(s).

Identity & game plan

• Win condition: Large Light and Darkness Ritual or Dark Time Wizard boards (Black Chaos, Black Luster Soldier, Black Skull Dragon, Magician of Dark Chaos) plus Extra Deck beaters (Red-Eyes Black Dragon Exceed, Number 39, Super Starslayer TY-PHON); Fusion and Link pressure from Predaplant Dragostapelia, Mediclius and Secreterion Dragon once the board is established
• Turn 1 (going first): Open a Dark Time Wizard or Light and Darkness Ritual searcher (Alligator's Dragon Knight, Mind Shuffle, Dark Time Wizard) and build toward a ritual or fusion board; disruption through Ash Blossom and Droll & Lock Bird
• Turn 2 (going second): Use Ash Blossom, Nibiru, Forbidden Droplet and Droll & Lock Bird to answer the opponent's board, then rebuild through Light and Darkness Ritual or Black Skull Dragon
• Recovery: Recursion through Foolish Graverobber, Griffoh, Mulcharmy Fuwalos and Skull Archfiend of Chaos from the GY; Fisherman of Legend as a counter-summon
• After siding: Not applicable: the deck runs no Side Deck (side_count 0), so there is no post-side plan

Why it scores here

The deck is illegal in its format: it runs one Forbidden card (Charmer Quartet in Bloom) and two copies of a Limited card (Droll & Lock Bird), so the normal Final Contextual score is capped and this result is theoretical and structural only. Its searcher density (about 78% to find at least one searcher in an opening 5) and its mix of Dark Time Wizard and Light and Darkness Ritual recursion give a plausible going-first engine, and the 3000+ ATK ritual and fusion boss set gives it closing power. Interaction is layered (6 hand traps, 6 negation-text cards, 18 removal-text cards), but no recorded boards exist, so combo floor and ceiling rest on text-only inference. The deck carries no Side Deck and runs 0% of the exact Umi archetype, with only 17.6% of the Umi usage-stat core present; popularity and archetype label did not earn points, and card scores were not averaged into the deck score.

Dimension scores

How the score was computed

Strategy profile: primary Midrange, secondary Toolbox (disclosed hybrid). Structural ≈ 51, Going First ≈ 55, Going Second ≈ 48, Meta = provisional, Tournament Reliability ≈ 45. Modifiers: banlist exposure (-10); no side deck (-2). Final formula: Illegal cap: uncapped 0.80*51 + 0.20*45 + modifiers (-12) ≈ 38, capped to 25 because the deck is illegal in OCG; theoretical/structural only

Probability & combo summary

• Opening a starter: P(≥1) ≈ 0.78 · 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

• Searcher density (11 searcher-text cards) gives a high chance of a live opening
• Layered interaction: 6 hand traps and 6 negation-text cards cover going-first and going-second turns
• Multiple 3000+ ATK ritual and fusion bosses give closing power
• Recursion from GY (Foolish Graverobber, Griffoh, Mulcharmy Fuwalos) keeps resources flowing

Weaknesses

• Illegal list: Charmer Quartet in Bloom is Forbidden and Droll & Lock Bird is over its Limited copy count
• No Side Deck, so no post-side adaptation
• The Umi archetype label does not match the list: 0% exact-name purity and only 17.6% of the Umi usage-stat core is present
• Ritual and fusion lines have many steps and conflicting summon requirements

Critical choke points

• The ritual engine depends on Light and Darkness Ritual, which is a single copy
• Every Extra Deck boss needs specific materials; a dead Extra Deck is common

Recommended changes

Evidence & confidence

• Verified: Illegal: Charmer Quartet in Bloom is Forbidden (1 copy) and Droll & Lock Bird is Limited (2 copies); Main 44, Extra 13, Side 0 against OCG size rules; Archetype label Umi: 0% exact-name purity and 17.6% of the Umi core present
• Observed: No recorded boards exist (combos_evidence.total_combos = 0)
• Inferred: Searcher density gives about 78% chance of a searcher in an opening 5; Layered interaction from hand-trap, negation and removal text; Engine conflict risk between Light and Darkness Ritual and Dark Time Wizard routes
• Provisional: Meta Power is null (no dated meta sample); Matchup and format fit are neutral placeholders
• 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 exists in YGOVN; going-first/second and matchup signals are Inferred or Unknown Meta Power is Provisional unless a dated metagame sample is supplied deck title is null
