Evil Twin Deck #772669 — Yu-Gi-Oh! OCG

Deck — Deck Power Evaluation

Final Contextual Deck Power: 33/100 (±8 · Confidence: Low)

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

Legality

Main 40 / Extra 15 / Side 0 — status under the rules at evaluation time: Illegal. 3 violation(s).

Identity & game plan

• Win condition: Link-summon the Evil★Twin link line (Evil★Twin's Trouble Sunny, Evil★Twin Lil-la, Evil★Twin Ki-sikil) off Live☆Twin / Ki-sikil / Lil-la starters, then convert with Fiendsmith and Fusion/Link boards; Fiendsmith's Lacrima / Fiendsmith's Rextremende board pressure and A Bao A Qu, the Lightless Shadow
• Turn 1 (going first): Open a Live☆Twin Ki-sikil or Lil-la starter, use Secret Password / Live☆Twin Sunny's Snitch to find the second Live☆Twin or Evil★Twin piece, and link into the Evil★Twin monsters; protect with Ash Blossom, Infinite Impermanence and Nibiru
• Turn 2 (going second): Use hand traps (Ash Blossom, Ghost Ogre & Snow Rabbit, Nibiru, Droll & Lock Bird) to disrupt the opponent's opening, then rebuild the Live☆Twin line from the GY via Lil-la Sweet and Ki-sikil Frost
• Recovery: Mulcharmy Fuwalos / Purulia draw while the hand is small; Fiendsmith's Tract and Fiendsmith Engraver search and recycle Fiendsmith pieces; Live☆Twin monsters revive from the GY
• After siding: Not evaluable: no side deck is present in the export (0 side cards); any post-side plan is unverified

Why it scores here

The score comes from the deck as a system, not from averaging its cards: the Live☆Twin / Ki-sikil / Lil-la starter layer gives roughly a 0.34 chance of any 3-copy starter in an opening 5 and about 0.90 for at least one of the 14 archetype-core copies, which supports a reasonable T1–T2 engine on paper. Interaction is the deck's strongest element, with 13 hand-trap-tagged cards (Ash Blossom, Infinite Impermanence, Nibiru, Ghost Ogre, Droll & Lock Bird) and a going-second hand-trap coverage of about 0.92 for at least one hand trap in six cards. Conversion, however, is unmeasured: there are no recorded boards, so the combo ceiling and median are text-only inferences and stay low. The deck runs three overlapping sub-engines (Live☆Twin, Evil★Twin link, Fiendsmith splash), has 0% exact-name archetype purity, and carries no side deck, which pulls down consistency and post-side scoring. Popularity (the Evil Twin archetype is present in usage stats) earned no points, and the score is capped low because the list is illegal: three cards exceed their copy limits.

Dimension scores

How the score was computed

Strategy profile: Combo. Structural ≈ 46, Going First ≈ 42, Going Second ≈ 47, Meta = provisional, Tournament Reliability ≈ 40. Modifiers: banlist exposure (-10); engine conflicts (-2). Final formula: 0.80*Structural + 0.20*TournamentReliability (Meta provisional); Illegal list → theoretical/structural-only, capped low

Probability & combo summary

• Opening a starter: P(≥1) ≈ 0.9 · 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

• 13 hand-trap-tagged cards give strong going-second interaction
• Full Evil★Twin link set and Fiendsmith fusion access in the Extra Deck
• Searcher density (10) supports starter consistency

Weaknesses

• Illegal copy counts: Engraver 3 (limit 1), Ash Blossom 3 (limit 2)
• No side deck, so no best-of-3 adaptation
• 0% exact-name archetype purity; three overlapping sub-engines
• No recorded combos, so ceiling and median are unmeasured

Critical choke points

• Live☆Twin Ki-sikil / Lil-la starter access (each 3-copy starter ≈ 0.34 in opening 5)
• Single Ki-sikil or Lil-la link piece needed to unlock the Evil★Twin links

Recommended changes

Evidence & confidence

• Verified: Illegal status: Ash Blossom & Joyous Spring 3 vs legal 2 (Semi-Limited); Illegal status: Fiendsmith Engraver 3 vs legal 1 (Limited); Main 40 / Extra 15 / Side 0 within OCG size rules; Extra Deck: 9 Link, 4 Fusion, 2 Xyz; Archetype purity 0% exact-name; 55 off-archetype copies
• Observed: Usage stats show the Evil Twin archetype at 100% for A Bao A Qu and 94% for Evil★Twin's Trouble Sunny (archetype context only, not deck results)
• Inferred: Starter consistency P(≥1) 0.34 per 3-copy card; core P ≈ 0.90; Hand-trap going-second coverage ≈ 0.92; Interaction quality from text role hints; Combo ceiling/median and closing power from card text
• Provisional: Meta Power (null, no dated metagame sample); Matchup and format fit (D13)
• Data gaps: Illegal list: score is theoretical/structural-only until copy limits are corrected No combos supplied — ceiling/median/floor are text-only inference No side deck — D12 and post-side plan are not evaluable No tournament link — archetype meta-share and per-pilot record absent No win-rate telemetry (going-first/second, matchup, brick/starter rates) Usage-stat inconsistency: Evil★Twin Ki-sikil, Evil★Twin Lil-la, Evil★Twin's Trouble Sunny, Evil★Twin Ki-sikil Deal, and Fiendsmith's Lacrima/Requiem appear in the Extra list yet are flagged in this deck:false in usage statistics; core coverage (33%) may be understated Meta Power is Provisional unless a dated metagame sample is supplied
