Live☆Twin Deck #765431 — Yu-Gi-Oh! Master Duel

Deck — Deck Power Evaluation

Final Contextual Deck Power: 44/100 (±7 · Confidence: Medium)

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

Legality

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

Identity & game plan

• Win condition: Extra Deck Link/Fusion boss (Evil★Twin's Trouble Sunny 3300 ATK, Fiendsmith's Rextremende 3000 ATK, Underworld Goddess 3000 ATK) reached through the Live☆Twin Ki-sikil / Lil-la loop and Fiendsmith GY/banish recursion; Fiendsmith's Lacrima / Desirae and Evil★Twin link monsters as follow-up boards after hand-trap interaction
• Turn 1 (going first): Normal Summon Live☆Twin Ki-sikil with no other monsters, which Special Summons a Lil-la monster from hand or Deck; then Ki-sikil Frost from hand if a Lil-la monster is controlled, and extend into a Link Summon. Requires Ki-sikil in the opening hand (about 34% per the hypergeometric estimate).
• Turn 2 (going second): Hold hand traps (Infinite Impermanence, Ghost Belle, Effect Veiler, Ghost Ogre, Droll & Lock Bird, Maxx C, Nibiru) to answer the opponent's first summons, then rebuild through Fiendsmith or Evil★Twin link monsters.
• Recovery: Mulcharmy Fuwalos and Purulia draw while the controller has no cards on field, Ghost Belle and Ghost Ogre recur from the GY, and Fiendsmith's Tract or Live☆Twin Sunny's Snitch search the next starter.
• After siding: None. The deck runs 0 side cards and the evidence has no post-side data; Master Duel ranked play does not provide a sideboard swap, so no post-side plan is credited.

Why it scores here

The deck opens a functional plan mainly through Live☆Twin Ki-sikil (3 copies, about 34% to see at least one in a 5-card opening hand), with Ki-sikil's own text enabling a Lil-la Special Summon. It converts that plan into pressure through Extra Deck Link and Fusion monsters, but the Extra Deck spans at least four sub-archetypes, so the engine is less cohesive than the single archetype name suggests. Its strongest score comes from interaction: 15 hand-trap-tagged main-deck copies and 13 negation-text cards give it a dense end-board layer and strong going-second answers. Scoring is on the system, not an average of card scores, and popularity was not credited; the archetype core proxy (97.6%) was discounted because it groups mixed sub-archetypes. Floor and median output are unmeasured because no boards were recorded, so the score is provisional on those dimensions.

Dimension scores

How the score was computed

Strategy profile: Stun 80 / Midrange 20 (applied as the Stun profile, with the Midrange engine effects reflected in D5 and D6). Structural ≈ 52, Going First ≈ 46, Going Second ≈ 56, Meta = provisional, Tournament Reliability ≈ 48. Modifiers: engine conflicts across sub-archetypes (-4); thin Lil-la base (-2); no side or post-side plan (-1). Final formula: 0.80*Structural + 0.20*TournamentReliability (Meta provisional) + ContextModifiers = 0.80*52 + 0.20*48 - 7 = 44

Probability & combo summary

• Opening a starter: P(≥1) ≈ 0.34 · 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: 15 hand-trap-tagged copies and 13 negation-text cards
• Multiple high-ATK Extra Deck bosses (2800-3300 ATK) for closing
• Compact 22-card distinct Main Deck with 3-copy caps on the core

Weaknesses

• Starter access is thin: about 34% for Ki-sikil in the opening hand
• Extra Deck spans at least four sub-archetypes with limited shared material
• No side deck and no post-side plan

Critical choke points

• Ki-sikil (3 copies) as the sole Live☆Twin starter; without it the Lil-la and Frost lines do not start
• Only 2 Lil-la monsters in the Main Deck to enable Ki-sikil Frost and Evil★Twin Lil-la

Recommended changes

Evidence & confidence

• Verified: Legal in Master Duel: 40 Main, 15 Extra, 0 Side within 0-15 side rules; all restricted cards at legal copy counts; Composition counts: 15 hand-trap-tagged copies, 13 negation-text, 12 removal-text, 4 searcher-text; Archetype spread: Fiendsmith 13, Mulcharmy 5, Live☆Twin 5, Evil★Twin 4, Ki-sikil 3, other 1-2 each
• Observed: Usage statistics show the archetype-standard core in the list for several core cards
• Inferred: P(at least one starter in opening hand) ≈ 0.34 from hypergeometric estimate; Interaction quality and resilience from card text; Going-second strength from hand-trap density
• Provisional: Meta Power (no dated metagame sample); Matchup and format fit (no tournament link)
• Data gaps: No combos supplied: combo floor, median and ceiling are text-only inference No tournament link: archetype meta-share and per-pilot match record absent usage statistics.in this deck is false for Extra Deck cards that are present in the cards list (for example Fiendsmith's Lacrima, Underworld Goddess, Fiendsmith's Requiem), so the core-present percentage (48%) ignores the Extra Deck and is not used No win-rate telemetry; going-first/second and brick rates are Inferred No guides attached (guide data total 0) Meta Power provisional without a dated metagame sample
