Live☆Twin Deck #770318 — Yu-Gi-Oh! Master Duel

Deck — Deck Power Evaluation

Final Contextual Deck Power: 50/100 (±8 · Confidence: Medium)

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

Legality

Main 41 / Extra 15 / Side 0 — status: Legal.

Identity & game plan

• Win condition: Live☆Twin Ki-sikil / Lil-la loop feeding Evil★Twin and Fiendsmith Link and Fusion boards (Evil★Twin's Trouble Sunny 3300 ATK, Underworld Goddess of the Closed World, Fiendsmith's Rextremende and Desirae); Fiendsmith ladder: Fiendsmith Lacrima / Fiendsmith in Paradise lines into Fusion and Link monsters; Fiendsmith's Lacrima gives -600 ATK to opposing monsters
• Turn 1 (going first): Open Ki-sikil or Lil-la; Normal Summon Ki-sikil with no other monsters to Special Summon Lil-la (or the reverse), then extend into Link Summons. Hold hand traps for the opponent's first activation.
• Turn 2 (going second): Hand-trap the opponent's starter (Infinite Impermanence, Ash Blossom, Ghost Belle, Ghost Ogre, Droll & Lock Bird, Maxx C), then use Forbidden Droplet or Crossout Designator to halve ATK and negate, and summon into the Link ladder.
• Recovery: Rebuild from the GY with Live☆Twin Lil-la Sweet and Ki-sikil Frost GY/hand summons, Fabled Lurrie GY summon, Fiendsmith Engraver and Sunny's Snitch searches, and Mulcharmy draw triggers.
• After siding: None: the export lists 0 side cards, so no post-side adaptation exists.

Why it scores here

The deck is legal and its Extra Deck is fully used (15 singleton Link, Fusion and Xyz monsters with several 2800+ ATK boss options), which gives it a real ceiling. Its consistency is weak: the Ki-sikil and Lil-la starter group (4 copies) has roughly a 42% chance of appearing in a going-first 5-card hand (Inferred), and 16 of 41 Main Deck cards are hand traps that do nothing on the deck's own turn. Its strength is interaction: a 96% chance of at least one hand trap in a going-second 6-card hand, plus Droplet and Crossout for board-breaking, and several independent routes (Live☆Twin, Evil★Twin, Fiendsmith) that let it recover from a single disruption. The score comes from consistency, interaction and route redundancy on the system, not from the Live☆Twin archetype's popularity, and not from averaging card scores; there are no recorded boards and no tournament or meta data, so Meta Power stays provisional and combo output is Inferred. The no-side-deck and three-engine-family conflicts cap the score.

Dimension scores

How the score was computed

Strategy profile: 70% Combo / 30% Stun; D13 dropped and remaining weights renormalized over 93.7 (meta-neutral). Structural ≈ 56.1, Going First ≈ 50, Going Second ≈ 62, Meta = provisional, Tournament Reliability ≈ 46.3. Modifiers: engine conflicts (-2); unrecoverable choke point (-2). Final formula: 0.80*Structural + 0.20*TournamentReliability + ContextModifiers (Meta provisional; D13 dropped and weights renormalized over 93.7): 0.80*56.1 + 0.20*46.3 - 4 = 50.1

Probability & combo summary

• Opening a starter: P(≥1) ≈ 0.42 · 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

• Legal in format: 41 Main, 15 Extra, all restricted cards at legal copy counts
• Full 15-card Extra Deck with several 2800+ ATK boss options
• 16 hand traps and 14 negation texts give high going-second interaction
• Multiple engine families (Live☆Twin, Evil★Twin, Fiendsmith) give independent routes

Weaknesses

• Going-first starter access is about 42% (Inferred)
• 16 of 41 Main Deck cards are hand traps that brick on the deck's own turn
• Three engine families with exact archetype purity 8.9%
• No side deck, so no post-side plan
• Extra Deck is 15 singletons with no redundancy

Critical choke points

• Ki-sikil/Lil-la starter group (4 copies) gates the Live☆Twin loop
• Single Lil-la copy gates Ki-sikil Frost and the Lil-la loop
• Live☆Twin Normal Summon chain needs an empty field (no other monsters)

Recommended changes

Evidence & confidence

• Verified: Legality: 41 Main, 15 Extra, 0 Side; restricted cards Crossout Designator, Maxx C and Droll & Lock Bird are at legal copy counts; Card text from the excerpts for Droplet, Underworld Goddess, Lacrima, Trouble Sunny and Ki-sikil; 16 hand traps and 14 negation texts from role tags
• Inferred: Starter access about 0.42 in going-first 5-card hands; Hand-trap access 0.96 going second; Dimension scores D1 through D14 except D13
• Provisional: Meta Power is null and D13 matchup/format fit is provisional; Tournament reliability inputs for matchup variance are provisional
• 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 are absent No win-rate telemetry (going-first/second, matchup, brick and starter rates) Meta Power is Provisional without a dated metagame sample No side deck in the export: post-side performance cannot be scored usage_statistics marks 13 Extra Deck core cards as in_this_deck false although they are present in the Extra Deck (Lacrima, Necroquip, Desirae, Rextremende, Caesar, Ki-sikil Deal, Agnumday, Requiem, Evil Ki-sikil, Evil Lil-la, Sequence, Trouble Sunny, A Bao A Qu). The reported core_present_pct 44 is understated; roughly 24 of 25 core cards are present, and only Muckraker is truly missing.
