Deck — Deck Power Evaluation

Final Contextual Deck Power: 60/100 (±8 · Confidence: Medium)

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

Legality

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

Identity & game plan

• Win condition: Link-2 engine (Live☆Twin Ki-sikil / Lil-la into Evil★Twin links, with Evil★Twin's Trouble Sunny at 3300 ATK) and Fiendsmith/Spright fusion and link boards; Fiendsmith's Rextremende (3000 ATK) and Fiendsmith's Desirae (2800 ATK) once Fiendsmith pieces are live; Gigantic Spright only if its materials are present, which the list does not guarantee
• Turn 1 (going first): Open a Ki-sikil or Lil-la starter with Spright Blue, Spright Jet or Secret Password to reach a 2-card Live☆Twin bootstrap, then link into Evil★Twin monsters while holding Ash Blossom and Droll & Lock Bird
• Turn 2 (going second): Use the six-card hand to hold Ash Blossom, Droll & Lock Bird, Maxx "C" and Lil-la Sweet for negation or draws, then rebuild the Live☆Twin board or link out from the second-turn starter
• Recovery: Mulcharmy Fuwalos and Mulcharmy Purulia draw from an empty board, Lacrima the Crimson Tears and Fiendsmith Engraver recur from the GY, and Live☆Twin Home or Ki-sikil Frost re-summon Lil-la and Ki-sikil from the hand
• After siding: Not supported: the deck runs zero side-deck cards, so there is no post-side plan to evaluate

Why it scores here

The deck is scored as a system: it reliably opens a live Live☆Twin or Spright starter (about 94% to see one of the 16 archetype-core cards in a 5-card opening hand, and about 90% to see one of 14 searchers) and has redundant routes through Ki-sikil, Lil-la, Spright Blue and Spright Jet, so one disruption rarely ends the turn. Converting that into a board depends on the Live☆Twin-to-Evil★Twin link line, which has no recorded boards in the evidence, so the conversion ceiling (Evil★Twin's Trouble Sunny at 3300 ATK, Rextremende at 3000) is text-based and Inferred. Interaction is layered across six hand-traps-or-negations (Ash Blossom, Droll & Lock Bird, Maxx "C", Lil-la Sweet) and destruction or removal text on several links, which earns the endboard and going-second marks. The score is pulled down by a 18.2% exact-name archetype purity: the list mixes Live☆Twin, Fiendsmith, Spright and Mulcharmy engines, which compete for Extra Deck and main slots, and it runs zero side-deck cards, so it has no post-side plan at all. Popularity and archetype usage did not earn points; the deck's usage-stat overlap was used only to confirm a real, accessible list. No card scores were averaged.

Dimension scores

How the score was computed

Strategy profile: Combo. Structural ≈ 64, Going First ≈ 68, Going Second ≈ 64, Meta = provisional, Tournament Reliability ≈ 60. Modifiers: engine conflicts (-3); zero side deck (-1). Final formula: 0.80*Structural + 0.20*TournamentReliability + ContextModifiers (Meta provisional; no dated metagame sample). 0.80*64.4 + 0.20*60 = 63.5, then modifiers -4 = 59.5, rounded to 60

Probability & combo summary

• Opening a starter: P(≥1) ≈ 0.94 · 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

• Very high opening access to the archetype core (about 94% in a 5-card opener) and to searchers (about 90%)
• Redundant Live☆Twin starters (Ki-sikil, Lil-la, Frost, Treat) and two searchers that each add a Spright
• Layered negation: Ash Blossom, Droll & Lock Bird, Maxx "C", Lil-la Sweet
• Extra Deck carries high-ATK end-board links (Trouble Sunny 3300, Rextremende 3000)

Weaknesses

• Exact-name archetype purity 18.2%: four sub-archetypes compete for slots and Extra Deck access
• No side deck: no post-side adaptation in best-of-3
• Several main-deck cards are situational (Fabled Lurrie, Ki-sikil Frost, Lil-la Treat)
• Guides in the evidence are Vietnamese and only give general direction, not measured performance

Critical choke points

• The Live☆Twin Ki-sikil to Lil-la bootstrap: if both are answered before a link lands, the board may not rebuild in one turn
• Fiendsmith pieces need Fiend monsters on the field, which the Live☆Twin starters only partly provide

Recommended changes

Evidence & confidence

• Verified: Legal status in Master Duel: 40 Main, 15 Extra, 0 Side; Maxx "C" at 1 copy (Limited), Droll & Lock Bird at 2 copies (Semi-Limited); Archetype purity 18.2% exact-name; archetype spread as listed; Zero side-deck cards; No combo boards and no tournament link in the evidence
• Inferred: Archetype-core 0.9354 and searcher 0.90 opening-hand access from hypergeometric estimates; Live☆Twin bootstrap and link routes from card text; Interaction density and going-second hand-trap coverage from text and hand probability
• Provisional: Meta Power (no dated metagame sample); Matchup and format fit (no tournament or meta data); Median output (no recorded boards)
• 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 no win-rate telemetry (going-first/second, matchup, brick/starter rates) Meta Power is Provisional unless a dated metagame sample is supplied guides are Vietnamese snippets and not full text
