Umi Control Deck #508596 — Yu-Gi-Oh! Master Duel

Deck — Deck Power Evaluation

Final Contextual Deck Power: 58/100 (±7 · Confidence: Medium)

• Primary strategy: Control
• Secondary strategies: none
• Format: master-duel

Legality

Main 46 / Extra 15 / Side 0 — status: Illegal. 3 violation(s). Restricted cards run: Abyss Dweller (Forbidden), Called by the Grave (Limited), Foolish Burial Goods (Limited), Maxx "C" (Limited).

Identity & game plan

• Win condition: Control through Umi + continuous negation/removal; Outrace or lock opponents via spell-heavy control and incremental advantage
• Turn 1 (going first): Set Umi, develop board with WATER/Tuner enablers, use hand-trap disruption and incremental card advantage to outvalue opponent across turns.
• Turn 2 (going second): Six-card hand enables reactive disruption; answer key threats, trigger Umi while holding counter traps, then stabilize and grind.
• Recovery: Retune with Foolish Burial/Called by the Grave into Umi or Kairyu-Shin, recycle backrow, and re-establish control.
• After siding: Side into targeted floodgates and removal; rebuild Umi-centric board while holding main answers.

Why it scores here

The deck runs a Umi Control shell with strong spell/trap density and hand-trap disruption, giving it reliable T1–T2 activation (D1) but suffers from brick risk and key bans (D2). It is not a combo deck, so its ceiling is modest (D3) and its median output limited (D4); however it excels at sustained interaction (D7) and grinding value (D6). Going-second flexibility is present (D8) but offensive closing power is low (D9). Efficiency is decent given the 46-card main count (D10), while side options are present though not transformative (D12). Format fit is provisional (D13) and the deck is moderately pilotable (D14). Scores reflect the system overall, not an average of individual card power.

Dimension scores

How the score was computed

Strategy profile: Balanced. Structural ≈ 58, Going First ≈ 55, Going Second ≈ 52, Meta = provisional, Tournament Reliability ≈ 50. Modifiers: Illegal card presence (-5); No meta sample (-2); Control density (3). Final formula: 0.80*Structural + 0.20*TournamentReliability (Meta provisional)

Probability & combo summary

• Opening a starter: P(≥1) ≈ — · key two-card combo ≈ — · full-brick estimate ≈ 0.12 (all Inferred)
• Combo output: best PowerIndex —, median —, board-per-starter —
• Turn order: 0 going-first lines vs 0 going-second lines

Strengths

• Dense spell/trap network for sustained interaction
• Multiple independent starters for route redundancy
• Strong hand-trap and negation suite
• Solid tuning base for Synchro support
• Effective recovery tools (Called by the Grave, Foolish Burial)

Weaknesses

• Illegal card presence reduces legitimacy and consistency
• No dedicated OTK or high-ceiling combo line
• Offensive closing power is below average
• Meta adaptability capped without dated sample
• Key searcher overload can leave draws dead

Critical choke points

• Dependence on Umi availability for engine consistency
• Limited extra deck coverage for non-Synchro targets
• Brick potential in early hand without searcher follow-up
• Side deck impact is constrained by format unknowns

Recommended changes

Evidence & confidence

• Verified: Card text and banlist status from evidence.json; Deck structure and card counts from composition
• Observed: Interaction density (13 negation, 15 removal entries); Extra deck breakdown (12 Synchro, 1 XYZ, 2 Link)
• Inferred: D1–D14 scores based on probabilities, text hints, and composition; Brick estimate (12%) from key card gaps and hand-trap coverage; Going-second flexibility from 6-card hand and counter-trap presence
• Provisional: Meta Power (no dated metagame sample provided); Tournament reliability (no tournament link or match record)
• Data gaps: No combos supplied — combo floor/median/ceiling inferred from text only No win-rate telemetry in YGOVN export No dated metagame sample — Meta Power remains provisional No tournament link or per-pilot match record
