Evil Twin Deck #771328 — Yu-Gi-Oh! OCG

Deck — Deck Power Evaluation

Final Contextual Deck Power: 40/100 (±8 · Confidence: Low)

• Primary strategy: Combo
• Secondary strategies: Stun, 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: Evil Twin link beatdown: Live Twin Ki-sikil and Lil-la lead into Evil Twin links (Ki-sikil, Lil-la, Ki-sikil Deal, Trouble Sunny) for a high-ATK board (Inferred from card text).; Fiendsmith Extra Deck line (Lacrima, Desirae, Requiem, Sequence) and Super Starslayer TY-PHON as a backup finisher (Inferred).
• Turn 1 (going first): Open a Live Twin starter (Ki-sikil, Lil-la or Snitch search) and extend into an Evil Twin link on T1-T2; hand traps stay in hand as protection (Inferred).
• Turn 2 (going second): Hold Ash Blossom, Ghost Ogre, Effect Veiler and Nibiru as hand traps to disrupt the opponent's first summon, then rebuild through the Ki-sikil/Lil-la recursion (Inferred).
• Recovery: Recursion through Mulcharmy Fuwalos, Live Twin Ki-sikil Frost, the Lil-la GY revival and Fiendsmith GY effects (Inferred from card text).
• After siding: No side deck (0 cards), so there is no post-side plan; the list is fixed for every game (Verified).

Why it scores here

This is an illegal list: Ash Blossom & Joyous Spring runs 3 copies against an OCG limit of 2, and Fiendsmith Engraver runs 3 against a limit of 1, so the final score is capped low and the evaluation is structural only. The engine reads as reasonably accessible: the 15-copy archetype core has about a 92% chance of at least one live card in a 5-card opening hand (Inferred), and the Live Twin starters are backed by Sunny's Snitch and Secret Password searches. Interaction is dense, with 18 hand traps and about 98% odds of at least one in a 6-card going-second hand (Inferred), which earns the going-second and interaction dimensions. Brick risk, the lack of recorded boards to measure median output, and the absence of a side deck hold the score back, and the lack of any dated meta sample leaves Meta Power null. Popularity and archetype usage were not used to raise the score, and card scores were not averaged into it.

Dimension scores

How the score was computed

Strategy profile: Combo. Structural ≈ 55, Going First ≈ 50, Going Second ≈ 60, Meta = provisional, Tournament Reliability ≈ 42. Modifiers: illegal_list_cap (-12). Final formula: 0.80*Structural + 0.20*TournamentReliability + illegal-list modifier (-12); Meta Power provisional and not used. Structural 55 and TR 42 give 52.4, then -12 = 40.

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

• Dense interaction: 18 hand traps and about 98% odds of at least one in a going-second hand (Inferred)
• Multiple independent starters (Ki-sikil, Lil-la, Ki-sikil Frost, Snitch) and recursion routes (Inferred)
• High-ATK Extra Deck closers: Chaos Angel, TY-PHON, Trouble Sunny (Verified stats)

Weaknesses

• Illegal copy counts on Ash Blossom and Fiendsmith Engraver
• No side deck (0 cards) and no post-side plan
• High hand-trap count raises brick risk in hands without a live starter (Inferred)
• No recorded boards, so median output and combo ceiling are unmeasured

Critical choke points

• Live Twin Ki-sikil and Lil-la must both be drawn to start the Evil Twin link chain (Inferred)
• Engraver is Limited to 1 and runs 3, so the Fiendsmith line is unreliable until the list is legal (Verified)

Recommended changes

Evidence & confidence

• Verified: Legality: 40 Main, 15 Extra, 0 Side; Ash Blossom 3 vs 2 and Engraver 3 vs 1 are over the OCG limit; Card text and stats for every listed card; Composition counts (Link 10, Fusion 3, Synchro 1, Xyz 1; 18 hand traps); Usage stats show the 15-copy archetype core at 100% inclusion for A Bao A Qu and high inclusion for Trouble Sunny
• Inferred: Starter consistency: 0.34 per 3-copy card and 0.92 for the 15-copy core in a 5-card hand; Interaction density and going-second hand-trap odds (0.98 in 6 cards); Combo ceiling from text (Ki-sikil to Lil-la to Evil Twin links to Trouble Sunny); Going-first and going-second power estimates
• Provisional: Meta Power (null, no dated metagame sample); Matchup and format fit, including the guide's remark that pure Spright is weaker in OCG
• Data gaps: Illegal list: copy limits are broken for Ash Blossom and Fiendsmith Engraver, so this is a theoretical/structural read only No combos supplied, so median, floor and ceiling are text-only inference No tournament link: archetype meta share and per-pilot records are absent No win-rate telemetry (going-first/second, matchup, brick and starter rates) Data inconsistency: usage_statistics marks A Bao A Qu, Evil Twin's Trouble Sunny and Evil Twin Ki-sikil Deal as not in this deck (in_this_deck false), but they appear in the Extra Deck card list; the stats may be Main-Deck-only Deck title is null and the single guide snippet is truncated with no section data Meta Power is provisional unless a dated metagame sample is supplied
