Live☆Twin Deck #764860 — Yu-Gi-Oh! Master Duel

Deck — Deck Power Evaluation

Final Contextual Deck Power: 52/100 (±8 · Confidence: Medium)

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

Legality

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

Identity & game plan

• Win condition: Extra Deck link and fusion boards (Fiendsmith's Rextremende 3000 ATK, Underworld Goddess 3000 ATK, D/D/D Wave High King Caesar 2800 ATK, Fiendsmith's Desirae 2800 ATK) backed by Fiendsmith's Lacrima's -600 ATK field effect; Attrition through hand-trap negation and Mulcharmy draw effects (Fuwalos x3, Purulia x2) that convert a stalled board into card advantage
• Turn 1 (going first): Normal Summon Live☆Twin Ki-sikil (x3) to Special Summon a Lil-la from Deck to enable Ki-sikil Frost, or Fiendsmith Engraver (x2) to search a Fiendsmith card and open the Lacrima/Desirae line; hold one hand trap if the opening hand has it
• Turn 2 (going second): Use the six-card hand to hold Infinite Impermanence, Effect Veiler, Ghost Belle and Droll & Lock Bird against the opponent's first summon or set, then rebuild board through Fiendsmith or Live☆Twin monsters into an Extra Deck link
• Recovery: Fuwalos and Purulia draw when the hand is empty; Fiendsmith's Tract and Live☆Twin Sunny's Snitch search; Fiendsmith in Paradise and Engraver recur from the GY
• After siding: No side deck is registered (side count 0), so the deck has no post-side plan; it relies on main-deck hand traps for all matchups

Why it scores here

The deck is scored as a system, not as an average of card scores. Its strongest feature is interaction: 15 hand traps, Crossout Designator, two Forbidden Droplets and Extra Deck negators (Fiendsmith's Desirae, Underworld Goddess, Caesar) give it broad, layered control of the opponent's board, and the chance of holding at least one hand trap in a six-card going-second hand is about 95% (Inferred). Its weakest feature is opening-hand reliability. The three engine families (Live☆Twin/Ki-sikil, Fiendsmith, Mulcharmy) only partly overlap, and the Ki-sikil entry is live in about 34% of going-first openers (Inferred). Ki-sikil Frost needs a Lil-la on the field, and only two Lil-la monsters are in the Main Deck. The combo evidence is empty, so the conversion ceiling and floor are inferred from card text only. Popularity did not earn points: the archetype is recognised, but the list runs only 9.1% exact-name Live☆Twin cards, and the score comes from interaction and Extra Deck closing power on the system, not from the archetype's reputation.

Dimension scores

How the score was computed

Strategy profile: Midrange weights applied in full; Stun noted as secondary and not blended because no dated meta sample exists. Structural ≈ 59, Going First ≈ 57, Going Second ≈ 70, Meta = provisional, Tournament Reliability ≈ 52. Modifiers: Engine conflict (-4); Hand-trap dead-card density (-3); Banlist exposure (-1); Engine compactness (2). Final formula: 0.80*Structural + 0.20*TournamentReliability + ContextModifiers (Meta provisional)

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

• Layered interaction: 15 hand traps plus Crossout Designator, two Forbidden Droplets and Extra Deck negators (Verified card text)
• Extra Deck closing power: Rextremende, Underworld Goddess, Caesar and Desirae all reach 2800 to 3000 ATK (Verified stats)
• Compact Main Deck: 22 distinct cards, with key cards at 3 copies for consistency (Verified)
• All 15 Extra Deck cards are used across three engine families (Verified)

Weaknesses

• Opening-hand reliability is low: the Ki-sikil entry is live in about 34% of going-first openers (Inferred)
• Ki-sikil Frost is conditional on a Lil-la, and only two Lil-la monsters are in the Main Deck (Verified card text, Inferred impact)
• Hand traps are dead on the going-first side when the opponent has no monster or Spell/Trap (Inferred)
• Three overlapping engine families (Live☆Twin, Fiendsmith, Mulcharmy) and only 9.1% exact-name Live☆Twin cards weaken coherence (Verified)
• No side deck, so no post-side plan (Verified)

Critical choke points

• A Live☆Twin Ki-sikil or Fiendsmith Engraver opener is needed to start the Live☆Twin or Fiendsmith line; without one, the hand is mostly hand traps and Mulcharmy draw cards (Inferred)
• Ki-sikil Frost needs a Lil-la on the field; if the two Main Deck Lil-la monsters are not drawn or summoned, Frost copies are dead (Inferred)

Recommended changes

Evidence & confidence

• Verified: Legality: Legal, 40 Main, 15 Extra, 0 Side, no violations (Master Duel size rules); Hand traps: 15 copies by role tag, and Extra Deck split of 10 Link, 4 Fusion, 1 XYZ; Exact-name Live☆Twin purity 9.1% (5 of 55 Main cards); Restricted cards: Crossout Designator (Limited, 1 of 1), Maxx C (Limited, 1 of 1), Droll & Lock Bird (Semi-Limited, 2 of 2)
• Observed: Usage statistics show the Extra Deck core (13 Extra cards flagged as missing in the usage block) is present in the card list; the flag is a join artifact, not a missing-card signal
• Inferred: Opening-hand reliability: Ki-sikil at least once in 5 ≈ 0.34; hand trap in 6 going second ≈ 0.95; dead hand-trap rate going first; Dimension scores D1 to D9, D11 and D14 from card text and hypergeometric estimates; Going-first and going-second power components
• Provisional: Meta Power (null) and D13 format fit, because no dated metagame sample or tournament link exists
• Data gaps: No recorded combo boards, so combo ceiling, floor and median (D3, D4) are inferred from text only usage_statistics marks 13 Extra Deck core cards as in_this_deck:false, but all 13 are present in cards[] at zone extra; the 48% core_present figure is a join artifact and is not used No tournament link: archetype meta-share and per-pilot record are absent No win-rate telemetry exists for going-first, going-second, matchups or brick rate Meta Power is provisional without a dated metagame sample No side deck registered, so D12 is scored on composition only
