Spright Deck #762015 — Yu-Gi-Oh! Master Duel

Deck — Deck Power Evaluation

Final Contextual Deck Power: 61/100 (±6 · Confidence: Medium)

• Primary strategy: Combo
• Secondary strategies: Midrange, Link/Xyz mechanic
• Format: master-duel

Legality

Main 40 / Extra 2 / Side 0 — status: Legal.

Identity & game plan

• Win condition: Chain Level/Link/Rank-2 monsters through Spright Starter and their own Special Summon triggers, then convert into Gigantic Spright (Xyz) and Spright Elf (Link) pressure; Spright Gamma Burst gives all Level/Rank/Link-2 monsters +1400 ATK for a turn, turning the chain board into lethal attack
• Turn 1 (going first): Normal Summon a Level-2 monster (any of the 21 Level-2 main-deck monsters), then Spright Starter or Quick Special Summon chains from hand
• Turn 2 (going second): Open with a Level-2 monster into the same chain; use Cosmic Cyclone or Forbidden Lance for interaction; Dark Hole only as a reset when behind
• Recovery: Spright Smashers and Spright Gamma Burst recur from the GY by banishing; Spright Jet and Spright Blue search a Spright card, and Ipiria draws 1
• After siding: Not applicable: Master Duel is single-game and side_count is 0 (Provisional)

Why it scores here

The deck reliably opens a live engine: 21 of its 40 Main Deck cards are Level-2 monsters that can Special Summon each other from hand once one Level-2 monster is on the field, so the Inferred chance of at least one Level-2 monster in an opening 5-card hand is about 0.98. Conversion is real but costly: Spright Starter and Cosmic Cyclone charge LP, and no recorded boards exist, so the ceiling and median are text-only inferences. Interaction comes from six negation-capable Carrot and Red copies, Cosmic Cyclone, Dark Hole and Forbidden Lance, but the deck runs no hand traps and Dark Hole can wipe its own engine. The structural score is the Combo-profile weighted sum of the 14 system dimensions, then context modifiers; no individual card scores were averaged, and the deck's popularity in usage statistics earned no points, only confirmation that the list is a real, accessible build.

Dimension scores

How the score was computed

Strategy profile: Combo. Structural ≈ 63.4, Going First ≈ 66, Going Second ≈ 60, Meta = provisional, Tournament Reliability ≈ 62. Modifiers: Engine compactness (2); Engine conflict (-2); LP cost of Starter and Cosmic Cyclone (-2). Final formula: 0.80*Structural + 0.20*TournamentReliability + ContextModifiers (Meta provisional): 0.80*63.4 + 0.20*62 = 63.1; modifiers -2 gives 61.1

Probability & combo summary

• Opening a starter: P(≥1) ≈ 0.34 · key two-card combo ≈ 0.33 · full-brick estimate ≈ 0.02 (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 engine: 21 Level-2 monsters give near-certain opening access (Inferred)
• Redundant starters and recursion (Starter x3, Smashers x2, Gamma Burst x2) (Verified card text)
• Negation plus two Extra-Deck finishers in a compact 40-card build (Verified)

Weaknesses

• No hand traps or floodgates, so the deck cannot answer an opponent's first turn cheaply (Verified tag counts)
• LP-heavy conversion: Starter and Cyclone cost LP (Verified text)
• Dark Hole conflicts with the engine it sits beside (Inferred)
• No recorded combos or win-rate data, so the ceiling and median are not measured (Verified gap)

Critical choke points

• Needing one Level-2 monster on field before the Starter line works (Inferred)
• Single-copy Extra-Deck cards (Spright Elf, Gigantic Spright) against typical 2-copy usage (Verified stat)

Recommended changes

Evidence & confidence

• Verified: Legality Legal: 40 Main, 2 Extra, 0 Side; size rules 40-60 / 0-15 / 0-15; All cards Unlimited under BanMasterDuel; no restricted cards; copies at or below legal limit; Archetype purity 64.3% exact Spright; 15 off-archetype copies; Card text excerpts for Carrot, Red, Starter, Gamma Burst, Smashers, Cosmic Cyclone, Dark Hole, Forbidden Lance, Gigantic Spright, Spright Elf; Usage stats: Spright Elf and Gigantic Spright typical 2 copies each
• Inferred: Opening access ~0.98 (Level-2 density) and Starter ~0.34 per hand; Chain conversion, ceiling and floor from text, not recorded boards; Interaction quality from negation and removal text; LP cost burden and Dark Hole self-conflict; Going-first and going-second estimates
• Provisional: Meta Power (null) and D13 matchup fit (neutral 50); Side adaptability D12 (neutral 50; single-game format)
• Data gaps: No combos supplied: combo floor, median and ceiling are text-only inference (combos_evidence.total_combos = 0) No tournament link: archetype meta-share and per-pilot record absent No win-rate telemetry: going-first/second, matchup and brick rates are Inferred or Unknown Meta Power is Provisional without a dated metagame sample Usage-statistics in_this_deck flags mark Gigantic Spright and Spright Elf as absent, but cards[] lists each once in the Extra zone; core_present_pct 31.8% therefore undercounts Extra-zone cards (likely a preprocessor counting only the Main zone) Negation text is truncated in description_excerpt, so the exact hand-versus-field activation window for Carrot and Red is unconfirmed
