Live☆Twin Deck #770324 — Yu-Gi-Oh! Master Duel

Deck — Deck Power Evaluation

Final Contextual Deck Power: 55/100 (±5 · Confidence: Medium)

• Primary strategy: Midrange
• Secondary strategies: Stun, Combo
• Format: master-duel

Legality

Main 40 / Extra 15 / Side 0 — status: Legal.

Identity & game plan

• Win condition: Live☆Twin Ki-sikil/Lil-la loop feeding Evil★Twin link monsters, mainly Evil★Twin's Trouble Sunny (3300 ATK) and Evil★Twin Lil-la, with Live☆Twin Lil-la Sweet recursion from the GY; Extra-Deck boss attackers such as A Bao A Qu, D/D/D Wave High King Caesar and Unchained Soul Lord of Yama, usable only when their Fiend or Link material is present
• Turn 1 (going first): Open with Live☆Twin Lil-la or Ki-sikil, chain the self-summon loop to reach a Ki-sikil and Lil-la pair, use Sunny's Snitch or Secret Password to search, then Link Summon Evil★Twin monsters from the Extra Deck
• Turn 2 (going second): Keep a hand trap (Ash Blossom, Infinite Impermanence, Droll & Lock Bird, Effect Veiler) for the opponent's first search or Special Summon, then rebuild the Live☆Twin loop and link out on the following turn
• Recovery: Lil-la Sweet revives from the GY once a Ki-sikil is on the field, Ki-sikil and Lil-la re-enter the loop through the Deck and GY, and Evil★Twin Ki-sikil can Link Summon again after Lil-la is recovered
• After siding: None: the deck runs 0 side-deck cards, so no post-side plan exists in the evidence

Why it scores here

The deck reliably opens its engine: the Live☆Twin core (Ki-sikil, Lil-la, Sunny's Snitch, Ki-sikil Frost) gives an archetype-core P(at least one in a 5-card opening hand) of about 0.96, and the self-summon loop recovers from the GY through Lil-la Sweet. Interaction is dense for a midrange list, with 12 hand traps, Crossout Designator, Dominus Spark and Ghost Ogre, which lifts the endboard and going-second scores. Consistency is held back by the 12 hand traps that are dead when the opponent does nothing, and by an Extra Deck that splits across Evil★Twin (4 supported cards), Fiendsmith (5 cards with only 4 LIGHT Fiend main-deck monsters to feed them) and 6 off-engine singletons. The score comes from engine consistency, interaction and going-second strength on the system, not from averaging the card scores and not from Live☆Twin being a popular archetype; there is no combo board data, no tournament link and no side deck, so the median and the post-side plan are inferred or absent.

Dimension scores

How the score was computed

Strategy profile: Midrange. Structural ≈ 60.6, Going First ≈ 60, Going Second ≈ 66, Meta = provisional, Tournament Reliability ≈ 55. Modifiers: Engine conflict (Fiendsmith Extra Deck) (-3); Banlist exposure (-1). Final formula: 0.80*Structural + 0.20*TournamentReliability + ContextModifiers (Meta provisional): 0.80*60.6 + 0.20*55 - 4 = 55.5

Probability & combo summary

• Opening a starter: P(≥1) ≈ 0.96 · 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

• Archetype-core loop has near-certain access (about 0.96 for at least one core card in an opening 5)
• Dense interaction suite: 12 hand traps plus Crossout, Dominus Spark and Ghost Ogre
• Strong Extra-Deck attackers, including Evil★Twin's Trouble Sunny at 3300 ATK
• Legal at every size and copy limit with no violations

Weaknesses

• 12 hand traps are dead without opponent action, which raises going-first brick risk
• Extra Deck has 5 Fiendsmith cards with only 4 LIGHT Fiend main-deck monsters to support them
• 6 off-engine Extra-Deck singletons dilute the engine
• No side deck, so no post-side adaptation
• 8 of 25 archetype-standard core cards are present (32%), so the build drifts from the archetype norm

Critical choke points

• Ki-sikil and Lil-la must both be live for the main loop and for Evil★Twin Link Summons; losing both to a single removal or hand trap stalls most lines
• Fiendsmith Extra-Deck links depend on LIGHT Fiend main-deck monsters, which are scarce

Recommended changes

Evidence & confidence

• Verified: Legal size (40 Main, 15 Extra, 0 Side) and all copy limits met; Card text and copy counts for all 40 Main and 15 Extra cards; Usage statistics: 8 of 25 archetype core cards present; Composition: 12 hand traps, 8 searcher-text cards, 11 negation-text cards, 9 removal-text cards
• Inferred: Archetype-core P(>=1 in opening 5) ≈ 0.96 and loop reliability; Going-second hand-trap coverage ≈ 0.90; Interaction density and endboard quality; Engine conflict between Fiendsmith Extra cards and the 4 LIGHT Fiend main-deck monsters; Going-first brick risk from hand traps
• Provisional: Meta Power (no dated metagame sample); Matchup and format fit (D13); Post-side plan (no side deck)
• Data gaps: no combos supplied — combo floor/median/ceiling is text-only inference no tournament link — archetype meta-share and per-pilot match record absent no win-rate telemetry exists in YGOVN (going-first/second, matchup, game-level, brick/starter/OTK rates) — those signals are Inferred or Unknown Meta Power is Provisional unless a dated metagame sample is supplied Side deck is empty, so post-side adaptability cannot be measured No deck title (title is null), so the build is identified only by archetype and card list
