Clown Crew Deck #754369 — Yu-Gi-Oh! Master Duel

Deck — Deck Power Evaluation

Final Contextual Deck Power: 35/100 (±8 · Confidence: Low)

• Primary strategy: Midrange
• Secondary strategies: Tempo, Toolbox
• Format: master-duel

Legality

Main 40 / Extra 14 / Side 0 — status under the rules at evaluation time: Illegal. 1 violation(s).

Identity & game plan

• Win condition: Clown Crew Tribute Summon chains (Cappello, Flair, Malabarisme, Rehearsal) to reach Clown Crew Biancaviso and Fydraulis Harmonia pressure (Inferred from card text); Double piercing and second-attack pressure from Clown Crew Diabolo and Clown Crew Dristy, both absent from this list (Inferred)
• Turn 1 (going first): Clown Crew Rehearsal or Malabarisme on turn 1 to reach a Ritual or Tribute Summon line, with Ash Blossom and Effect Veiler held up as interaction (Inferred)
• Turn 2 (going second): Hand traps (Ash Blossom, Effect Veiler, Ghost Ogre, Droll and Lock Bird, Ghost Belle, Maxx C) to answer the opponent's first board, then Clown Crew recovery through Flair and Malabarisme (Inferred)
• Recovery: Ghost Belle and Clown Crew Flair recursion from the GY, plus Clown Crew New Face draw and Biancaviso draws (Inferred from card text)
• After siding: Not evaluable: the deck runs no Side Deck, so there is no post-side plan

Why it scores here

The deck reliably opens its Clown Crew core: the archetype-core group has a hypergeometric P(at least one in a 5-card opening hand) of about 0.999, and four Clown Crew engine cards run 3 copies each (Inferred, from the probabilities block). Hand traps (13 cards, P(at least one in a 6-card hand) about 0.92) give it a credible answer to a first board when going second. Conversion is the weak point: no recorded boards exist, so the combo ceiling and median are text-only inferences and are scored conservatively. Popularity was not credited: the archetype usage stats and the guide confirm the list is real, but they did not add points to the score. The score is not an average of card scores. It is capped low because Dimension Shifter, a Forbidden card, is run in a Master Duel deck, which makes this list illegal as built and places it in theoretical, structural-only territory.

Dimension scores

How the score was computed

Strategy profile: Balanced (default; strategy is ambiguous without combo evidence). Structural ≈ 55, Going First ≈ 58, Going Second ≈ 62, Meta = provisional, Tournament Reliability ≈ 42. Modifiers: banlist exposure (Forbidden card in format) (-12); illegal-deck cap (-5). Final formula: Illegal deck: 0.80*Structural(55) + 0.20*TournamentReliability(42) = 52.4, then banlist modifier -12 = 40.4, then capped to 35 as theoretical/structural-only per the Illegal rule; Meta Power provisional (null)

Probability & combo summary

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

Strengths

• Near-certain archetype-core access in the opening hand
• Thirteen hand traps and layered negation give going-second resilience
• Multiple draw and recursion effects support recovery across turns

Weaknesses

• Illegal as built: Dimension Shifter is Forbidden in master-duel
• Only 48.1% exact-name archetype purity; 14 tech slots dilute the engine
• No Side Deck, so no post-side adaptation
• No recorded boards, so the ceiling and median are unverified

Critical choke points

• Clown Crew Rehearsal and Malabarisme are the engine starters; the guide also names them as the choke point
• Dimension Shifter's legality must be fixed before any competitive read applies

Recommended changes

Evidence & confidence

• Verified: Deck is Illegal: Dimension Shifter (Forbidden, 1 copy) in master-duel; Main 40, Extra 14, Side 0 are within master-duel size rules; Archetype usage statistics show the Clown Crew core is standard for this list; Archetype purity is 48.1% by exact name
• Inferred: Engine accessibility from hypergeometric estimates; Going-second hand-trap coverage from hypergeometric estimates; Combo ceiling and resilience from card text only; Interaction quality from text role hints
• Provisional: Format fit and meta position (no dated metagame sample or tournament link)
• Data gaps: no combos supplied; combo floor/median/ceiling is text-only inference no tournament link; archetype meta-share and per-pilot match record absent no win-rate telemetry exists in YGOVN; going-first, going-second and matchup signals are Inferred or Unknown Meta Power is Provisional unless a dated metagame sample is supplied no Side Deck, so post-side performance cannot be assessed
