Spright Deck #761970 — Yu-Gi-Oh! Master Duel

Deck — Deck Power Evaluation

Final Contextual Deck Power: 25/100 (±8 · Confidence: Low)

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

Legality

Main 43 / Extra 15 / Side 0 — status: Illegal. 3 violation(s).

Identity & game plan

• Win condition: Link and Xyz boss monsters (Evil★Twin's Trouble Sunny, Underworld Goddess, Knightmare Gryphon, Divine Arsenal) built from Spright and Live☆Twin Level/Rank/Link 2 bodies; Live☆Twin Ki-sikil and Lil-la pressure through the Evil★Twin link line
• Turn 1 (going first): Open Spright Starter or a Live☆Twin searcher, Special Summon Level/Link 2 bodies, and link into a boss while holding hand traps for the opponent's first response
• Turn 2 (going second): Hold Ash Blossom, Ghost Belle, Ghost Ogre, Infinite Impermanence and Maxx "C" to answer the opponent's first summon or activation, then rebuild the board from Spright Jet, Spright Blue and the Live☆Twin line
• Recovery: Spright Gamma Burst and Lil-la Treat recurse from the GY; Secret Password and the Spright searchers refill the hand
• After siding: No side deck is registered, so there is no post-side plan to evaluate (Inferred)

Why it scores here

This list is Illegal in master-duel: Called by the Grave is Forbidden and runs in two copies, and Maxx "C" runs three copies against a limit of one, so the score is structural and theoretical only and is capped at 25. Structurally, the deck reliably opens a Spright or Live☆Twin starter (P(at least one Spright Starter in a 5-card opening) ≈ 0.32, and the archetype core group gives P(at least one core card) ≈ 0.96), and it has a dense interaction layer (about 15 negation and 13 removal texts, 13 hand-trap-tagged cards, P(at least one hand trap in a 6-card going-second hand) ≈ 0.90). Its closing power comes from Extra-Deck links and Xyz bosses that a Level/Link 2 chain can reach. The deck scores low on combo conversion and floor because no recorded boards exist, so both values are text-only inference, and it scores low on side-deck adaptability because it registers no side deck. Popularity and archetype usage were not used to raise the score, and card scores were not averaged into the deck score.

Dimension scores

How the score was computed

Strategy profile: Midrange weights (no meta sample, D13 kept at Midrange weight). Structural ≈ 53, Going First ≈ 50, Going Second ≈ 52, Meta = provisional, Tournament Reliability ≈ 45. Modifiers: banlist exposure (-10); no side deck (-2). Final formula: Unclamped blend 0.80*53 + 0.20*45 = 51.4 (Meta provisional), then modifiers -12 gives 39; Illegal cap sets the final score to 25 (theoretical/structural only)

Probability & combo summary

• Opening a starter: P(≥1) ≈ 0.32 · 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

• Archetype core is almost always reachable (P ≈ 0.96 for at least one core card in an opening hand)
• Dense hand-trap and negation layer that covers the opponent's first response (P ≈ 0.90 for a hand trap in a 6-card going-second hand)
• Multiple independent Extra-Deck routes (11 Link, 4 Xyz) into high-ATK bosses

Weaknesses

• Illegal list: Called by the Grave is Forbidden and two copies are run; Maxx "C" is over its Limited limit
• Low archetype purity (27.6%) across Spright and Live☆Twin sub-archetypes and generic tech
• No side deck registered

Critical choke points

• Spright Starter (3 copies) is the only explicit Main Deck starter, so opening without one falls back to hand-trap-only play

Recommended changes

Evidence & confidence

• Verified: Illegal status: Called by the Grave (Forbidden, 2 copies) and Maxx "C" (Limited, 3 copies); Main 43 and Extra 15 are within size rules; side is 0; Card texts and stats for listed cards (Ash Blossom, Ghost Belle, Spright Starter, Evil★Twin's Trouble Sunny, Underworld Goddess, Divine Arsenal)
• Inferred: P(>=1 Spright Starter in 5) ≈ 0.32; core group ≈ 0.96; hand-trap group ≈ 0.90 (hypergeometric); Interaction density and resilience read from negation and removal text; Consistency and brick estimates from role tags
• Provisional: Meta Power (no dated metagame sample); Matchup fit (D13 placeholder 50)
• 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/second, matchup, game-level, brick/starter/OTK rates) — those signals are Inferred or Unknown Meta Power is Provisional unless a dated metagame sample is supplied No side deck registered, so post-side performance cannot be assessed
