Spright Deck #755501 — Yu-Gi-Oh! OCG

Deck — Deck Power Evaluation

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

• Primary strategy: Combo
• Secondary strategies: Toolbox, Midrange
• Format: ocg

Legality

Main 40 / Extra 15 / Side 0 — status under the rules at evaluation time: Illegal. 1 violation(s).

Identity & game plan

• Win condition: Evil★Twin's Trouble Sunny (3300 ATK Link-4) and the other large Link/Fusion boards (Underworld Goddess, A Bao A Qu, Fiendsmith's Desirae) built from the Live☆Twin / Evil★Twin summon chain; Fiendsmith's Lacrima and Fiendsmith engine recursion from the GY; Nibiru as a one-card board reset
• Turn 1 (going first): Summon Live☆Twin Ki-sikil or Lil-la, let its on-summon effect bring out the other Twin monster, then Link Summon Evil★Twin Ki-sikil / Lil-la to build a board; use Secret Password or Sunny's Snitch to find the next piece
• Turn 2 (going second): Hold Infinite Impermanence, Ash Blossom, Effect Veiler, Maxx "C" and Droll & Lock Bird for hand-trap disruption against the opponent's first summons, then rebuild the Twin chain from the GY
• Recovery: Mulcharmy Fuwalos / Purulia draw when the opponent Summons, Live☆Twin monsters re-summon from the GY, and Fiendsmith's Tract and Engraver refill the hand
• After siding: None: the deck has no Side Deck (side_count 0), so there is no post-side plan

Why it scores here

This is a mixed-engine list: a Live☆Twin / Evil★Twin summon chain (Ki-sikil and Lil-la starters into Evil★Twin Links) with a Fiendsmith package, Mulcharmy draw monsters and Unchained/Fabled/Knightmare fillers, and only 7.3% of its main deck carries the exact Spright name. The core Twin engine is coherent, but the opening-hand estimate is weak: P(at least one Live☆Twin Ki-sikil in an opening hand of 5) is about 0.34 and P(at least one of the 8-copy archetype core) is about 0.69, so the engine often starts late (Inferred). Hand-trap density is high (11 tagged cards, P(at least one in a 6-card going-second hand) ≈ 0.88), which lifts interaction and going-second resilience. The deck has no recorded boards, so ceiling and median output are text-only inference and carry low confidence. The deck is Illegal as built because Knightmare Gryphon is Forbidden in OCG, so the score is capped low and labelled structural-only. Popularity did not earn points, and card scores were not averaged into the deck score.

Dimension scores

How the score was computed

Strategy profile: Combo. Structural ≈ 53, Going First ≈ 50, Going Second ≈ 58, Meta = provisional, Tournament Reliability ≈ 45. Modifiers: banlist exposure: Forbidden card run (-8); no side deck (-3). Final formula: No reliable metagame: 0.80*Structural + 0.20*TournamentReliability + ContextModifiers = 0.80*53 + 0.20*45 - 11 = 40.4, capped to 35 because the deck is Illegal (Forbidden card in the Extra Deck). Score is theoretical/structural only.

Probability & combo summary

• Opening a starter: P(≥1) ≈ 0.34 · 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

• Compact Twin engine: Ki-sikil and Lil-la summon each other and feed Evil★Twin Links
• High interaction density: 11 hand traps / negations (Impermanence, Ash Blossom, Veiler, Maxx "C", Droll & Lock Bird, Nibiru)
• Multiple high-ATK Link and Fusion closers (3300, 3000, 2800, 2800)
• Draw and search redundancy: 10 searcher-text cards and Mulcharmy draw effects

Weaknesses

• Illegal as built: Knightmare Gryphon is Forbidden and run 1 copy
• Low exact-name purity (7.3%): four or more sub-engines compete for slots
• No side deck: no post-side plan
• Opening-hand starter access is weak (~34% for a single Twin starter)
• Mulcharmy 'if you control no cards' conditions conflict with Twin board-building

Critical choke points

• Live☆Twin Ki-sikil / Lil-la on-summon must land to start the Evil★Twin line
• Knightmare Gryphon legality: the deck cannot be legally submitted until it is replaced
• Single-copy Fiendsmith and Limited cards (Lacrima, Engraver, Tract) gate the second engine

Recommended changes

Evidence & confidence

• Verified: Main 40 / Extra 15 / Side 0 counts are within the OCG size rules; Knightmare Gryphon is Forbidden and over the copy limit (1 run, 0 legal); Other restricted cards (Droll & Lock Bird, Engraver, Lacrima, Tract, Maxx "C", S:P Little Knight) are at their Limited limit of 1; Ash Blossom is at its Semi-Limited limit of 2; Card text and printed ATK/DEF values for every distinct card are in the evidence; Exact-name archetype purity is 7.3%
• Observed: Archetype usage stats: 6 of 16 core cards present (37.5%)
• Inferred: Hypergeometric opening-hand estimates (starter, archetype core, searcher, hand trap); Dimension scores D1–D11 and D14 from card text and composition; Strategy classification as Combo with Toolbox/Midrange secondary
• Provisional: Meta Power (null) and D13 matchup/format fit; Tournament reliability
• 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) Meta Power is Provisional unless a dated metagame sample is supplied deck title is null in the export no side deck present: post-side plan unknown
