Evil Twin Deck #771534 — Yu-Gi-Oh! OCG

Deck — Deck Power Evaluation

Final Contextual Deck Power: 30/100 (±8 · Confidence: Low)

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

Legality

Main 40 / Extra 15 / Side 0 — status under the rules at evaluation time: Illegal. 2 violation(s).

Identity & game plan

• Win condition: Large Link/Xyz boards anchored by Evil★Twin's Trouble Sunny (3300 ATK) and the Light and Darkness Ritual boss pair (Black Chaos, Black Luster Soldier); Fiendsmith and Djinn Link/Xyz follow-ups that convert advantage from the Ki-sikil/Lil-la starters
• Turn 1 (going first): Open a Live☆Twin Ki-sikil or Lil-la starter (3 copies each), Special Summon the Lil-la or Ki-sikil partner, then Link into Evil★Twin boards. Interaction is held back for the opponent's turn.
• Turn 2 (going second): Stack hand traps (Ash Blossom, Maxx 'C', Droll & Lock Bird, Effect Veiler, Infinite Impermanence, Crossout Designator) to stop the first summon, then rebuild through the Ki-sikil/Lil-la starters.
• Recovery: Graveyard recursion through Live☆Twin Sunny's Snitch, Mind Shuffle, Lacrima the Crimson Tears, and Evil★Twin Lil-la/Ki-sikil Link Summons from the GY.
• After siding: None. The deck has no Side Deck, so there is no post-side plan and no best-of-3 adaptation.

Why it scores here

The deck reliably opens a starter only moderately often: the Ki-sikil/Lil-la core (11 archetype copies) gives about an 82% chance of at least one in an opening 5, but the Live☆Twin starters are single-card bootstraps with a 34% chance per copy (Inferred). Its going-second strength is the most credible part of the list, with about 88% chance of at least one hand trap in a 6-card hand (Inferred), and its closing power comes from 3000-ATK ritual bosses and a 3300-ATK Link 4. Those scores come from the system, not from averaging card power, and the archetype's popularity earned no points. The list is illegal (two Forbidden cards), has no Side Deck, and has zero recorded boards, so the score is capped and theoretical only.

Dimension scores

How the score was computed

Strategy profile: Midrange. Structural ≈ 54, Going First ≈ 55, Going Second ≈ 62, Meta = provisional, Tournament Reliability ≈ 45. Modifiers: banlist exposure (-6); engine conflict (-4). Final formula: 0.80*Structural(54.25) + 0.20*TournamentReliability(45) = 52.4; modifiers -10 gives 42.4; Illegal legality cap sets final to 30 (theoretical/structural only; Meta provisional)

Probability & combo summary

• Opening a starter: P(≥1) ≈ 0.82 · key two-card combo ≈ — · full-brick estimate ≈ 0.18 (all Inferred)
• Combo output: best PowerIndex —, median —, board-per-starter —
• Turn order: 0 going-first lines vs 0 going-second lines

Strengths

• Eleven hand traps and nine searcher-text cards give a deep interaction and search base
• Three-copy Live☆Twin starters and Ki-sikil/Lil-la cover the opening starter
• Strong going-second hand-trap density (~88% in a 6-card hand, Inferred)
• Closing boards with 3000-ATK ritual bosses and a 3300-ATK Link 4

Weaknesses

• Illegal in OCG: two Forbidden cards in the Extra Deck
• No Side Deck, so no post-side plan
• Three sub-engines with 0% exact-name purity
• No recorded boards or combo evidence to confirm any line

Critical choke points

• The Live☆Twin Ki-sikil/Lil-la starter, which carries the opening (Inferred)
• Forbidden Extra Deck cards must be removed before the list is legal

Recommended changes

Evidence & confidence

• Verified: Main 40 and Extra 15 are within size rules; Knightmare Gryphon and D/D/D Wave High King Caesar are Forbidden with 1 copy each; Limited cards are run at their limit (1 copy); Side Deck is empty
• Observed: Usage stats show the Evil★Twin core is present in only part of this list (33% core present)
• Inferred: Starter probabilities (0.82 core, 0.34 per Live☆Twin copy) from the hypergeometric estimates; Going-second hand-trap density (0.88); Engine conflict and brick estimates
• Provisional: Meta Power and matchup coverage (no dated metagame sample); Tournament reliability
• Data gaps: No recorded combos: floor, median, and ceiling are text-only inference No tournament link: archetype meta-share and match record absent No win-rate telemetry for going-first/second, matchup, or brick/starter rates No Side Deck, so post-side adaptation cannot be assessed Deck title is null Meta Power remains provisional
