Spright Deck #773795 — Yu-Gi-Oh! Master Duel

Deck — Deck Power Evaluation

Final Contextual Deck Power: 53/100 (±6 · Confidence: Medium)

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

Legality

Main 40 / Extra 15 / Side 0 — status: Legal.

Identity & game plan

• Win condition: Link/Fusion boss pressure: Evil★Twin's Trouble Sunny (3300 ATK) and Fiendsmith's Rextremende (3000 ATK), supported by Desirae and Lacrima; Chip damage and board control through Live☆Twin lifegain and Lil-la attack taxes, with Mulcharmy card draw as a backup
• Turn 1 (going first): Summon a Level 2 monster (Spright Blue, Spright Jet, or a Live☆Twin Ki-sikil/Lil-la), search with Secret Password or Spright Blue/Jet, then link into Evil★Twin Ki-sikil or Lil-la and reach Fiendsmith or Evil★Twin Extra Deck bosses
• Turn 2 (going second): Hold Ash Blossom, Droll & Lock Bird, or Maxx 'C' for the opponent's first summon or search, then rebuild with Live☆Twin Home or Fiendsmith's Tract into an Extra Deck boss
• Recovery: Searchers (Spright Blue, Spright Jet, Fiendsmith Engraver, Fiendsmith's Tract) and Gigantic-style recursion from the GY rebuild a second Level 2 or Link-2 line after a hand-trap or negate
• After siding: Not applicable: Master Duel has no side deck in this list (Side Deck size 0)

Why it scores here

The deck reliably opens a Level 2 body: the archetype-core group (16 copies) has about a 93.5% chance of at least one card in a 5-card opening hand, and 14 searcher-text cards add bridge options (Inferred). Its Extra Deck converts that into real pressure through Evil★Twin's Trouble Sunny (3300 ATK), Rextremende, and Desirae, and the Live☆Twin lifegain and Lil-la attack tax add pressure during the midgame (Verified text, Inferred conversion). Six hand traps and several negates give it a real interruption layer, but the four overlapping lines (Live☆Twin, Spright, Fiendsmith, Mulcharmy) dilute the core: exact-name archetype purity is only 18.2%, and no combo boards were recorded, so the floor and median are unmeasured. Popularity and usage statistics were NOT credited as power, and no card scores were averaged; the score comes from consistency, closing bosses, and interaction on the system, with no meta sample to lift it.

Dimension scores

How the score was computed

Strategy profile: Midrange. Structural ≈ 59, Going First ≈ 61, Going Second ≈ 60, Meta = provisional, Tournament Reliability ≈ 55. Modifiers: Engine compactness (-3); Engine conflicts (-2). Final formula: 0.80*Structural + 0.20*TournamentReliability (Meta provisional) + ContextModifiers = 0.80*59 + 0.20*55 - 5 ≈ 53

Probability & combo summary

• Opening a starter: P(≥1) ≈ 0.94 · key two-card combo ≈ — · full-brick estimate ≈ 0.07 (all Inferred)
• Combo output: best PowerIndex —, median —, board-per-starter —
• Turn order: 0 going-first lines vs 0 going-second lines

Strengths

• Dense Level 2 body count (23) with 14 searcher-text cards gives reliable access to the engine on turn 1-2
• Six hand traps and negates (Ash Blossom 3, Droll & Lock Bird 2, Maxx 'C' 1, Lil-la Sweet, Desirae) cover both turns
• Extra Deck closers reach 2800-3300 ATK with layered removal and negation on the Extra side

Weaknesses

• Only 18.2% exact-name archetype purity: four engines compete for 40 main slots
• Mulcharmy needs an empty field, which conflicts with the Live☆Twin and Spright lines
• No side deck in Master Duel, so there is no post-side adjustment
• Combo floor and median are unmeasured because no boards were recorded

Critical choke points

• Live☆Twin Ki-sikil or Lil-la must be present for the Evil★Twin Link route; each has only 2 copies (about 24% in a 5-card hand)
• Fiendsmith's Tract and Engraver are the only Fiendsmith search routes, and both need LIGHT Fiend monsters in hand or deck
• A single opposing Ash Blossom or Droll on the first summon can stall the Level 2 chain

Recommended changes

Evidence & confidence

• Verified: Legal 40 main / 15 extra / 0 side in master-duel; Maxx 'C' Limited 1 copy and Droll & Lock Bird Semi-Limited 2 copies, both within limits; Card text and stats for the Extra Deck bosses (Trouble Sunny 3300 ATK, Rextremende 3000 ATK, Desirae 2800 ATK); Archetype-core group 16 copies with P(≥1 in hand5) ≈ 0.9354 and searcher-text group 14 copies ≈ 0.90
• Observed: Usage statistics: 25 core cards tracked; 7 present in this list (28%)
• Inferred: Consistency read from hypergeometric draw odds and searcher density; Floor and ceiling of the Live☆Twin, Fiendsmith, and Spright lines from text only; Hand-trap coverage on going second (about 65%)
• Provisional: Meta power and matchup fit: no dated metagame sample and no tournament link; Side-deck adaptability: Master Duel with no side deck
• Data gaps: No combos supplied: combo floor, median, and ceiling are text-only inference No tournament link: archetype meta-share and per-pilot record absent No win-rate telemetry (going-first/second, matchup, brick/starter rates) Meta Power is Provisional: no dated metagame sample supplied
