Spright Deck #755155 — Yu-Gi-Oh! OCG

Deck — Deck Power Evaluation

Final Contextual Deck Power: 35/100 (±10 · Confidence: Low)

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

Legality

Main 55 / Extra 15 / Side 0 — status: Illegal. 3 violation(s).

Identity & game plan

• Win condition: Live Twin Ki-sikil and Lil-la chain into Evil Twin Link Monsters and Evil Twin's Trouble Sunny (3300 ATK) for pressure; Fiendsmith Lacrima and Fiendsmith Desirae end-boards if the Fiendsmith lines connect (Inferred from text)
• Turn 1 (going first): Open Live Twin monsters and a Spright or Live Twin searcher, then link into Evil Twin monsters; Forbidden cards are not legal and cannot be run
• Turn 2 (going second): Hand traps (Ash Blossom, Ghost Ogre, Effect Veiler, Infinite Impermanence) to interrupt the opponent's first summon, then Live Twin summon chains (Inferred)
• Recovery: Live Twin Lil-la Treat and Live Twin Home recover Ki-sikil and Lil-la monsters; Evil Twin monsters can Special Summon from the GY (Inferred from text)
• After siding: No side deck (0 cards); no post-side plan exists in this list

Why it scores here

The list is illegal in OCG: three Forbidden cards (Triple Tactics Talent, Knightmare Gryphon, D/D/D Wave High King Caesar) are run, so the score is a theoretical, structural-only read capped at 35. The Live Twin Ki-sikil and Lil-la summon chain gives a moderate chance of an early engine (about 0.61 that at least one of the nine core copies is in an opening 5-card hand, Inferred), and 16 hand traps give good interaction on the going-second turn (about 0.89 for at least one in a 6-card hand, Inferred). The deck is not a coherent single-archetype engine: only 8.6 percent of cards are exact Spright-name matches, and 64 of 70 copies sit outside the Spright archetype name, so the score reflects how the systems interact rather than a popularity or card-average estimate. It has no side deck and no recorded boards, so its floor, median and ceiling are unmeasured and it cannot be credited for a post-side plan. The score was not built from averaging card scores.

Dimension scores

How the score was computed

Strategy profile: Midrange primary, Toolbox secondary (disclosed; Toolbox weights not applied separately). Structural ≈ 52, Going First ≈ 48, Going Second ≈ 55, Meta = provisional, Tournament Reliability ≈ 40. Modifiers: banlist_exposure (-10); engine_conflicts (-2). Final formula: Theoretical only (Illegal): 0.80*Structural(52) + 0.20*TournamentReliability(40) + modifiers(-12) = 37.6, capped at 35 for illegal status; Meta provisional

Probability & combo summary

• Opening a starter: P(≥1) ≈ 0.61 · 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

• Strong hand-trap and negation suite (16 hand traps, 18 negation-text cards) for the going-second turn
• Coherent Link Monster backbone with 12 Link Monsters in the Extra Deck, including Evil Twin's Trouble Sunny at 3300 ATK
• Recursion from the GY through Live Twin Lil-la Treat and Live Twin Home

Weaknesses

• Illegal in OCG: three Forbidden cards (verified)
• Low archetype purity: 8.6 percent exact-name, 64 off-archetype copies, so the engine is split across several themes
• No side deck, so no post-side adaptability

Critical choke points

• Any Live Twin summon chain relies on Ki-sikil and Lil-la being summoned in the right order
• Removing the three Forbidden cards leaves no stated replacement, so the list must be rebuilt before it can be scored as legal

Recommended changes

Evidence & confidence

• Verified: Three Forbidden cards are run over the copy limit (legality); Main Deck 55 cards and Extra Deck 15 cards, both within OCG size rules; No side deck (0 cards); Ash Blossom & Joyous Spring at 2 copies is Semi-Limited and legal; Usage stats: 16 archetype stat rows, 7 of 16 core cards present (43.8 percent)
• Inferred: Opening-hand access probabilities (hypergeometric); Dimension scores D1 to D14; Strategy and role classification from card text; Turn-1 and turn-2 plans
• Provisional: Meta Power (null); no dated metagame sample; D13 matchup and format fit (set at neutral 50)
• 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 for OCG; going-first, going-second and matchup rates unknown Meta Power provisional without a dated metagame sample Deck is illegal, so the Final score is a theoretical cap, not a legal-deck score
