Evil Twin Deck #768577 — Yu-Gi-Oh! OCG

Deck — Deck Power Evaluation

Final Contextual Deck Power: 30/100 (±10 · Confidence: Low)

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

Legality

Main 40 / Extra 15 / Side 0 — status: Illegal. 1 violation(s).

Identity & game plan

• Win condition: Evil★Twin Link Monsters (Trouble Sunny 3300 ATK, Deal, Lil-la, Ki-sikil) summoned off the Live☆Twin Ki-sikil / Lil-la / Sunny's Snitch engine (Inferred from card text; no recorded boards); Fiendsmith Fusion/Link pressure via Lacrima and Engraver if the Fiendsmith splash is live (Inferred)
• Turn 1 (going first): Open on a Live☆Twin Level 2 starter, Special Summon a Lil-la or Ki-sikil, then link into an Evil★Twin monster (Inferred from card text, not a recorded line)
• Turn 2 (going second): Hold Ash Blossom, Ghost Ogre, Effect Veiler, Droll or Maxx C to answer the opponent's first board, then rebuild through Ki-sikil and Lil-la (Inferred)
• Recovery: Recover through Snitch, Secret Password and Fiendsmith's Tract searches and GY Lil-la Sweet / Lil-la Treat revival (Inferred)
• After siding: None: the Side Deck is empty (0 cards), so there is no post-side plan

Why it scores here

The Evil Twin list reliably opens a starter about 92% of the time across its 15 archetype-core copies in a going-first hand (hypergeometric, Inferred), which keeps the Live☆Twin Ki-sikil / Lil-la engine accessible. Its interaction package is broad (ten hand traps, nine negation-text cards, and twelve removal-text cards), and the Evil★Twin Link Monsters and Trouble Sunny give it real closing power on the system. The score is held back by a 55-copy off-archetype mix across Live☆Twin, Fiendsmith, Mulcharmy, Forbidden and Dominus, a zero-card Side Deck, and no recorded combo boards to confirm the median output. The list is illegal because it runs one Forbidden copy of D/D/D Wave High King Caesar, so the score is capped and reported as a structural read only; popularity and archetype usage did not earn points, and card scores were not averaged.

Dimension scores

How the score was computed

Strategy profile: Combo. Structural ≈ 55, Going First ≈ 50, Going Second ≈ 58, Meta = provisional, Tournament Reliability ≈ 48. Modifiers: banlist exposure (-8); engine conflicts (-4). Final formula: No reliable metagame: uncapped Final = 0.80*Structural(55) + 0.20*TournamentReliability(48) + ContextModifiers(-12) ≈ 42; capped to 30 because the list is Illegal (rubric Step 2, theoretical/structural-only)

Probability & combo summary

• Opening a starter: P(≥1) ≈ 0.92 · 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

• Starter reliability: about 92% chance of at least one archetype-core card in a going-first opener (Inferred)
• Ten hand traps and nine negation-text cards give several answers to the opponent's first turn (Inferred)
• Extra Deck closing power: Trouble Sunny 3300 ATK, Underworld Goddess 3000 ATK, TY-PHON 2900 ATK (Verified stats)

Weaknesses

• Illegal list: Caesar (Forbidden) is in the Extra Deck, so the deck cannot be entered as built
• No Side Deck: zero post-side options against any matchup
• Low archetype purity: 55 off-archetype copies across five sub-archetypes weaken engine coherence
• No combo evidence: floor and median output cannot be confirmed

Critical choke points

• The Live☆Twin Ki-sikil / Lil-la starter line: if the 2-card starter is stopped, the Evil★Twin link route is slow to rebuild (Inferred)
• Forbidden Caesar in the Extra Deck: the list cannot be played legally until it is removed

Recommended changes

Evidence & confidence

• Verified: Main 40, Extra 15, Side 0 are within the OCG size rules; Caesar is Forbidden, 1 copy run, 0 legal copies: illegal; Limited cards are run at their legal limits; Copy histogram sums to 40 main-deck cards; Extra Deck stats (Trouble Sunny 3300, Underworld Goddess 3000, TY-PHON 2900)
• Observed: Guide note: pure Spright is weak in OCG after the banlist (text only, no measured frequency)
• Inferred: Starter access about 0.92 (hypergeometric); Hand-trap coverage about 0.85 going second; Consistency, brick and interruption ratings from card text and composition; Combo ceiling and floor estimates from text only
• Provisional: Meta power and matchup fit: no dated metagame sample or tournament link
• Data gaps: no combos supplied: combo floor, median and ceiling are text-only inference no tournament link: meta-share and per-pilot match record absent no win-rate, going-first/second, matchup or brick telemetry in YGOVN Meta power provisional without a dated sample usage_statistics marks Extra-Deck cards (Trouble Sunny, Deal, Evil★Twin Lil-la, Ki-sikil, Sequence, Requiem, Lacrima, Desirae, A Bao A Qu, S:P Little Knight) as in_this_deck:false even though they appear in the deck with zone extra. core_present_pct 44.4 is therefore an artifact of the matcher ignoring the Extra Deck and should not be read as off-core usage. Side Deck is empty: post-side performance cannot be assessed
