Harpie Deck #763588 — Yu-Gi-Oh! OCG

Deck — Deck Power Evaluation

Final Contextual Deck Power: 36/100 (±8 · Confidence: Medium)

• Primary strategy: Midrange
• Secondary strategies: Combo, Toolbox
• Format: ocg

Legality

Main 41 / Extra 15 / Side 0 — status under the rules at evaluation time: Illegal. 2 violation(s).

Identity & game plan

• Win condition: Harpie Lady chain-summons and Extra Deck Link/Xyz/Synchro boards (Cyber Slash Harpie Lady, Mist Valley Apex Avian, Harpie Conductor, Divine Arsenal AA-ZEUS) overwhelm the opponent's board; Harpie's Pet Baby Dragon and Harpie Lady field pressure with Harpies' Hunting Ground ATK/DEF boosts
• Turn 1 (going first): Open Hysteric Sign or Harpie Lady Elegant Egotist, search or summon a Harpie Lady, then bounce a WIND monster with Harpie Dancer/Channeler to extend into a Link or Xyz board
• Turn 2 (going second): Use hand traps (Ash Blossom, Ghost Belle, Maxx C, Droll & Lock Bird) and Harpie's Feather Duster to break the opponent's first board, then rebuild through Harpie Lady recursion
• Recovery: Harpie Channeler and Harpie Perfumer recover Harpie monsters from the Deck; Harpie Queen and Hysteric Sign refill the hand from the GY
• After siding: No Side Deck is present, so no post-side plan can be evaluated; the list cannot be sided at all

Why it scores here

The deck can reliably open a Harpie Lady starter only about a third of the time: P(at least one of three copies in a 5-card opening hand) is roughly 0.33, though the searcher text group reaches about 0.73. Its conversion ceiling comes from Extra Deck breadth (Link, Xyz and Synchro boards, plus Apex Avian and AA-ZEUS as closers), and its interaction package (Hysteric Party, Feather Duster, Icarus Attack, Ash Blossom, Ghost Belle, Maxx C, Droll & Lock Bird) gives it real resilience against single disruptions. The score is held back by the absence of recorded boards, so the floor and median are text-only estimates, by a zero-card Side Deck, and by an 11-card off-archetype or generic main deck with 50% exact-archetype purity. The deck is Illegal in OCG: three copies of Divine Wind of Mist Valley exceed its limit of one, and Simorgh, Bird of Sovereignty is Forbidden and run once. The result is therefore theoretical and structural only, capped low, and it does not reflect any popularity or meta-share; the score was not derived by averaging card scores.

Dimension scores

How the score was computed

Strategy profile: Midrange. Structural ≈ 49, Going First ≈ 45, Going Second ≈ 52, Meta = provisional, Tournament Reliability ≈ 45. Modifiers: banlist exposure (-12). Final formula: Theoretical/structural only (Illegal). 0.80*49 + 0.20*45 = 48.2, then banlist-exposure modifier -12 gives 36. Meta Power provisional, excluded.

Probability & combo summary

• Opening a starter: P(≥1) ≈ 0.33 · 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

• Harpie Lady recursion and searchers (Hysteric Sign, Harpie Queen, Perfumer) give repeatable resource refill
• Five hand traps plus Feather Duster and Hysteric Party cover multiple interaction types
• Broad Extra Deck (Link, Xyz, Synchro) offers several boards and high-ATK closers

Weaknesses

• Illegal in OCG: Divine Wind over copy limit and Forbidden Simorgh present
• No Side Deck, so zero post-side adaptation
• 14 off-archetype or generic main cards reduce engine coherence
• No recorded boards, so floor and median are unmeasured

Critical choke points

• Harpie Lady starter access (P≈0.33 for 3 copies in a 5-card opener)
• Single Feather Duster and single Droll & Lock Bird as the only hard answers to spell and trap or search lines

Recommended changes

Evidence & confidence

• Verified: Illegal status: Divine Wind over limit (3 of 1), Simorgh Forbidden; Main 41, Extra 15, Side 0 counts; Card text for Harpie Lady, hand traps and Extra Deck boards; Copy histogram and archetype purity (50%)
• Inferred: Starter access and brick rate from hypergeometric draws; Interaction density and going-second value from card text; Closing power from ATK values and text; Pilotability from chain length
• Provisional: Meta Power and matchup fit: no dated metagame sample or tournament link
• Data gaps: no combos supplied — combo floor/median/ceiling is text-only inference no tournament link — archetype meta-share and per-pilot match record absent no win-rate telemetry exists in YGOVN — going-first/second, matchup and brick rates are Inferred or Unknown Meta Power is Provisional unless a dated metagame sample is supplied No guides attached (total_guides 0)
