Evil Twin Deck #763142 — Yu-Gi-Oh! OCG

Deck — Deck Power Evaluation

Final Contextual Deck Power: 36/100 (±12 · Confidence: Low)

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

Legality

Main 55 / Extra 15 / Side 0 — status under the rules at evaluation time: Illegal. 2 violation(s).

Identity & game plan

• Win condition: Evil★Twin link and Fiendsmith extra-deck pressure (Evil★Twin's Trouble Sunny 3300 ATK, Fiendsmith's Desirae 2800 ATK) converting a Live☆Twin / Lil-la chain-start into a board; Forbidden Knightmare Gryphon and D/D/D Wave High King Caesar, which cannot be legally played as listed
• Turn 1 (going first): Live☆Twin Lil-la or Ki-sikil starter, Sunny's Snitch or Secret Password to search, then link or fusion into a Fiendsmith or Evil★Twin extra-deck monster (text-based read, Inferred)
• Turn 2 (going second): Open with hand traps (Ash Blossom, Ghost Belle, Ghost Ogre, Droll & Lock Bird, Solemn Judgment) against the opponent's starter, then rebuild through Lil-la / Ki-sikil summons (Inferred)
• Recovery: Ki-sikil Frost and Lil-la Treat re-summon from hand or GY after a negated starter; Fiendsmith Engraver and Fiendsmith's Tract float searches (Inferred)
• After siding: No side deck is run (side_count 0), so there is no post-side plan; best-of-3 adaptation is unavailable as built

Why it scores here

This is a structural-only read because the list is Illegal: two Forbidden OCG cards (Knightmare Gryphon and D/D/D Wave High King Caesar) are run in the Extra Deck, so the score is capped and carries no normal Final Contextual weight. The deck reliably opens its Live☆Twin and Lil-la starter package (archetype-core group P(≥1 in 5) ≈ 0.86, Inferred), and it has enough hand traps and negations (14 hand traps, 20 negation-text cards) to cover the opponent's first play. Conversion is unverified because no recorded boards exist, so the ceiling and median are text-only inferences and are not scored above the midpoint. The off-archetype mix (0% exact-name purity across Live☆Twin, Fiendsmith, Solemn, Unchained, and Evil★Twin pieces) and the empty side deck pull the score down. Popularity and archetype usage did not earn points, and no card scores were averaged into the result.

Dimension scores

How the score was computed

Strategy profile: Combo. Structural ≈ 49.5, Going First ≈ 48, Going Second ≈ 56, Meta = provisional, Tournament Reliability ≈ 42. Modifiers: banlist_exposure (-6); engine_conflicts (-3); side_deck_empty (-3). Final formula: 0.80*Structural + 0.20*TournamentReliability (Meta provisional) = 0.80*49.5 + 0.20*42 = 48.0; minus 12 modifiers = 36; Illegal list, so this is capped and structural-only

Probability & combo summary

• Opening a starter: P(≥1) ≈ 0.86 · key two-card combo ≈ — · full-brick estimate ≈ 0.14 (all Inferred)
• Combo output: best PowerIndex —, median —, board-per-starter —
• Turn order: 0 going-first lines vs 0 going-second lines

Strengths

• Deep Live☆Twin / Lil-la starter package with three-copy redundancy
• 14 hand traps and 20 negation-text cards give going-second interaction
• Searchers (Sunny's Snitch, Secret Password, Engraver, Tract) plus recursion via Frost and Treat

Weaknesses

• Illegal as built: two Forbidden Extra Deck cards
• No side deck (side_count 0)
• Mixed engines: 0% exact-name Evil Twin purity across five sub-archetypes
• No recorded boards, so conversion cannot be measured

Critical choke points

• Live☆Twin Lil-la / Ki-sikil starter, which the Extra Deck link lines depend on
• Forbidden Extra Deck cards cannot be played, so the Extra Deck plan must be rebuilt

Recommended changes

Evidence & confidence

• Verified: Illegal: Knightmare Gryphon and D/D/D Wave High King Caesar are Forbidden in OCG (legal_copies 0); Main 55 and Extra 15 are within size rules; side 0 is within 0–15; Exact-name Evil Twin purity is 0% (70 off-archetype copies); Archetype-core group P(≥1 in opening 5) = 0.8557 across 17 copies; Guide 500 exists and describes an OCG post-banlist Spright/Evil Twin build
• Inferred: Starter access and brick rate from hypergeometric and text reads; Interaction density and going-second hand-trap coverage from negation and hand-trap text; Combo ceiling and floor are text-only (no recorded boards); Going-first and going-second scores from structural weights
• Provisional: Meta Power (null, no dated metagame sample); Matchup and format fit (D13, no tournament link)
• Data gaps: Illegal list: copies and banlist status are checked by the server, but the 2 Forbidden Extra Deck cards are in the export as run usage_statistics is internally inconsistent: Evil★Twin Ki-sikil Deal, Evil★Twin Ki-sikil, Evil★Twin Lil-la, Evil★Twin's Trouble Sunny, A Bao A Qu, and Fiendsmith's Lacrima / Requiem / Sequence / Desirae are marked in_this_deck=false and listed in missing_core, yet they appear in cards[] (Extra zone), so core_present_pct 44.4 and missing_core are unreliable No combos supplied (total_combos 0) No tournament link; archetype meta-share and pilot record absent No win-rate telemetry exists in YGOVN Meta Power is Provisional unless a dated metagame sample is supplied
