Harpie Deck #751057 — Yu-Gi-Oh! Master Duel

Deck — Deck Power Evaluation

Final Contextual Deck Power: 35/100 (±10 · Confidence: Low)

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

Legality

Main 40 / Extra 15 / Side 0 — status: Illegal. 1 violation(s).

Identity & game plan

• Win condition: Fire King and Garunix boss monsters (Garunix Eternity, High Avatar Garunix, Sacred Garunix, Raging Phoenix) built through searcher and link/xyz lines; Link beatsticks (Worldsea Dragon Zealantis, Promethean Princess, Amblowhale) once the board is clear
• Turn 1 (going first): Open a searcher (Fire King Courtier Ulcanix, Legendary Fire King Ponix, Fire King Avatar Barong) and convert into a Link or Xyz boss; hand traps are held back
• Turn 2 (going second): Hold Ash Blossom, Infinite Impermanence, Dominus Impulse, Ghost Belle or Nibiru to stop the opponent's first summon or activation, then recover into a Fire King boss
• Recovery: Fire King monsters recur from the GY (Garunix, Barong, Ulcanix text), and Fire King Island and Sanctuary keep field spells in play
• After siding: None: the deck runs no Side Deck (side_count 0), so there is no post-side plan to evaluate

Why it scores here

This list is a Fire King build carrying the Harpie label: only Harpie's Feather Duster matches the archetype name, and the 25 Fire King cards are the real engine. Its searchers (9 copies of searcher text, P(at least one in a 5-card opening) about 0.74) give a reasonable chance of finding a starter, and its eight hand traps (P(at least one in a 6-card opening when going second) about 0.76) give it real interaction on the second turn. Its Fire King and Garunix bosses, plus the Link material, give it closing power, but no combos were recorded, so the ceiling and median are text-only estimates. The score is structural only: the Fire King High Avatar Kirin copy count is over the master-duel limit, so the deck is capped low and gets no normal final score. The score was built from consistency, interaction and resilience on the system, not from averaging card scores, and popularity or archetype share earned no points.

Dimension scores

How the score was computed

Strategy profile: Midrange. Structural ≈ 56, Going First ≈ 55, Going Second ≈ 62, Meta = provisional, Tournament Reliability ≈ 45. Modifiers: banlist exposure: over copy limit (-8); no side deck (-4). Final formula: 0.80*Structural + 0.20*TournamentReliability (Meta provisional) = 53.8 before modifiers; modifiers -12 gives 41.8; illegal-list cap sets final at 35

Probability & combo summary

• Opening a starter: P(≥1) ≈ 0.74 · 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

• Eight hand traps and 12 negation-text cards give interaction on both turns
• Searchers and GY recursion give a reasonable chance of a live engine
• Garunix bosses reach 2700 to 3000 ATK

Weaknesses

• Over the master-duel copy limit for Fire King High Avatar Kirin, so the list is illegal
• No Side Deck
• Harpie label does not match the build (1 Harpie card), and the Harpie usage list does not describe this deck

Critical choke points

• Kirin copy count: the list cannot be played as-is until one copy is removed
• Searcher density: 9 searcher-text cards, so opening without one leaves the engine off

Recommended changes

Evidence & confidence

• Verified: Illegal: Fire King High Avatar Kirin 3 copies vs legal 2 (Semi-Limited); Main 40, Extra 15, Side 0 within master-duel size rules; Harpie's Feather Duster and Pot of Extravagance each run 1 copy, within their Limited status; Only 1 Harpie-named card and 25 Fire King cards in the list
• Inferred: Searcher and hand-trap hypergeometric odds; Interaction density and going-second read from card text; Engine accessibility and pilot demand
• Provisional: Meta and matchup placement (no dated metagame sample)
• 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 for going-first, going-second, matchup or brick rates Usage statistics describe a Harpie build (Gem-Knight core cards), not this Fire King list Meta Power is provisional until a dated metagame sample is supplied
