Harpie Deck #772761 — Yu-Gi-Oh! OCG

Deck — Deck Power Evaluation

Final Contextual Deck Power: 51/100 (±6 · Confidence: Medium)

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

Legality

Main 57 / Extra 15 / Side 0 — status: Legal.

Identity & game plan

• Win condition: Multi-Extra-Deck boss pressure: Magikey Fusion/Synchro/Xyz/Link monsters (Andrabime 2800, Transfurlmine 2800, Ashtartu 3000, Draco Berserker 3000) backed by Ritual Magikey Maftea/Mafteal lines; Tenyi/Adamancipator/Knightmare Extra Deck bosses reached through tech and searcher text
• Turn 1 (going first): Search Magikey World or Mafteal, Ritual or Fusion summon via Magikey Maftea, then extend into a Link or Synchro boss while holding hand traps (Crow, Lancea, Ghost Belle) for the opponent's turn
• Turn 2 (going second): Open a hand trap (about 56% at least one of Crow, Lancea, Ghost Belle, PSY-Framegear Gamma in six cards) to negate or banish the opponent's starter, then rebuild through Ritual searchers
• Recovery: Ritual searchers (Magikey Mechmusket, Mafteal, Manju, Preparation of Rites) and Magikey Duo / Battle recursion from the GY to rebuild a Ritual or Fusion starter
• After siding: No side deck is registered (side count 0), so there is no post-side plan; adaptability is limited to the main-deck tech cards

Why it scores here

The deck's consistency rests on a searcher-dense Magikey core: 16 searcher-text cards give about an 82% chance of at least one in an opening five, and three Magikey World give about a 24% chance of a live field plus Maftea access. The Ritual and Fusion starter, Magikey Maftea, is only two copies (about 17% in five), so the engine is real but thin at the top. Interaction is the strongest part of the system: seven hand traps, ten negation-text cards and sixteen removal-text cards cover both turns and support a going-second plan. The Extra Deck offers several independent boss routes (Fusion, Synchro, Xyz, Link), which helps resilience, but the sub-archetype spread (Magikey plus Archfiend, Tenyi, PSY-Frame, Knightmare, Adamancipator and World Chalice) costs coherence and pilotability. The score comes from consistency, interaction and route redundancy on the system; the Harpie archetype label, the 1.4% exact-name purity and the usage statistics did not earn points, and no card scores were averaged.

Dimension scores

How the score was computed

Strategy profile: Midrange primary, Toolbox secondary (about 80/20 by reading; the profile used is Midrange). Structural ≈ 59.3, Going First ≈ 63, Going Second ≈ 60, Meta = provisional, Tournament Reliability ≈ 50. Modifiers: Engine sprawl / conflicts (-3); No side deck (-2); Banlist exposure (-1). Final formula: 0.80*Structural + 0.20*TournamentReliability (Meta provisional) + ContextModifiers(-6) = 0.80*59.3 + 0.20*50 - 6 ≈ 51

Probability & combo summary

• Opening a starter: P(≥1) ≈ 0.24 · 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

• Dense searcher text (16 cards) gives about 82% access to a search in the opening five
• Seven hand traps and about 56% hand-trap access going second
• Several independent Extra Deck routes (Fusion, Synchro, Xyz, Link)
• High boss ceiling: 2800–3000 ATK Extra Deck monsters
• Interaction density across negation and removal text

Weaknesses

• Only two Maftea (the Ritual/Fusion starter) makes the top of the engine thin
• 28 spells in 57 main cards raises brick and conflict risk
• No side deck, so no post-side plan
• Sub-archetype sprawl reduces coherence and pilotability
• Harpie label does not match the list (1.4% exact-name purity)

Critical choke points

• Magikey Maftea (2 copies) as the Ritual/Fusion starter
• Magikey World (3 copies) as the Field Spell access point

Recommended changes

Evidence & confidence

• Verified: Legal OCG list: 57 Main, 15 Extra, 0 Side; all Limited cards at 1 copy; Five Limited one-copy cards; hand-trap and searcher text tags from the evidence pack; Boss ATK values (2800–3000) from card data; Feather Duster usage 61.5% from usage statistics
• Inferred: Opening-hand probabilities (hypergeometric) and the brick estimate; Interaction density and semantic negation reads from card text; Going-first and going-second plans; Extra Deck route redundancy and pilotability
• Provisional: Meta Power and matchup fit (no dated metagame sample)
• 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 side deck registered (side count 0) no guides for the archetype (guide data total 0)
