Harpie Deck #767042 — Yu-Gi-Oh! OCG

Deck — Deck Power Evaluation

Final Contextual Deck Power: 53/100 (±6 · Confidence: Medium)

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

Legality

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

Identity & game plan

• Win condition: Magikey Fusion/Ritual/Xyz/Synchro boards (Magikey Deity - Ashtartu, Magikey Dragon - Andrabime, Magikey Fiend - Transfurlmine) built from Magikey Maftea and Magikey Mafteal, with Draco Berserker and Adamancipator Risen as off-engine Synchro payoffs.; Direct-attack pressure from Synchro and Link beaters (Draco Berserker of the Tenyi, Adamancipator Risen - Dragite, Draco Masters of the Tenyi).
• Turn 1 (going first): Open a Magikey starter (Mafteal, Clavkiys, Manju, Dai, or Preparation of Rites) and search or set up Magikey World or Maftea, then make a Fusion, Ritual or Xyz summon. Expect 1-2 cards of dead weight if the opening is not Magikey-dense.
• Turn 2 (going second): Use Crow, Lancea, Ghost Belle, Magikey Locking or Unlocking to answer the first turn, then build the Magikey board. Raigeki and Harpie's Feather Duster are the reset buttons.
• Recovery: Recover Maftea and Duo from the GY, use Magikey Battle and Maftea's GY effects to rebuild, and re-search with Manju, Prep and World.
• After siding: None. The deck runs 0 side cards in a format that allows up to 15, so no post-side plan exists in the submitted list.

Why it scores here

The deck is a Magikey build labelled Harpie: only one copy of Harpie's Feather Duster and no Harpie monsters, with 27 Magikey-related cards and a large off-archetype tail. Its Ritual and Fusion chain runs through Magikey Maftea (2 copies), which has only about a 17 percent chance of appearing in a 5-card opening, so the starter is thin. Searchers and multi-copy Normal-monster starters (Mafteal, Clavkiys, Manju, Dai, Preparation of Rites) lift consistency to a moderate level, while seven hand traps give going-second resilience. The deck's ceiling rests on Magikey Ashtartu, Andrabime and Transfurlmine, but nine non-Magikey Extra Deck cards and a 0-card side dilute the plan. These scores come from the system as a whole (starter access, interaction density and Extra Deck coherence), not from averaging card scores. Popularity was not credited, and there is no recorded combo or tournament evidence, so the output is held to Medium confidence.

Dimension scores

How the score was computed

Strategy profile: Midrange. Structural ≈ 57, Going First ≈ 58, Going Second ≈ 60, Meta = provisional, Tournament Reliability ≈ 55. Modifiers: No sideboard (-2); Extra Deck dilution (-1); Single-point starter (-1). Final formula: 0.80*Structural + 0.20*TournamentReliability + ContextModifiers (Meta provisional; no dated meta sample)

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

• Multiple searchers and Normal-monster starters give moderate consistency (Inferred).
• Seven hand traps plus Magikey Unlocking and Locking provide going-second interaction.
• Strong Extra Deck closers at 2800 to 3000 ATK with board-destruction effects.

Weaknesses

• Maftea (2 copies) is the single-point Ritual and Fusion enabler with low opening-hand presence.
• Nine off-archetype Extra Deck cards dilute the Magikey engine.
• Empty side deck leaves no post-side plan.
• Off-engine tech bricks (Water Magician, Alligator's Sword, Raigeki, Dragon's Mirror) lower opening-hand quality.

Critical choke points

• Magikey Maftea (2 copies): required for most Ritual and Fusion routes.
• Single-copy Magikey Locking, Duo and Mechmortar: each is an unrecoverable piece of the interaction suite.

Recommended changes

Evidence & confidence

• Verified: Legal: 57 main, 15 extra, 0 side; the format allows 40-60 main, 0-15 extra, 0-15 side.; Five Limited cards, each run at 1 copy, all within legal limits.; Magikey Maftea runs 2 copies; the Harpie label is 1.4 percent exact-name purity.
• Inferred: Consistency estimate from hypergeometric draw odds and searcher density (about 0.24 for 3-copy cards in hand5).; Going-second hand-trap coverage of about 0.56.; Semantic read of Ashtartu, Andrabime and Transfurlmine as the closing and ceiling route.
• Provisional: Meta Power and matchup fit: no dated metagame sample or tournament link.; Side-deck adaptability: no side cards submitted.
• Data gaps: No combos supplied, so 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 exists in YGOVN; going-first, going-second and matchup signals are Inferred or Unknown. Deck archetype is labelled Harpie, but the list is primarily Magikey. The label may be wrong; verify it in the DB. Side deck is empty; post-side performance cannot be scored. Meta Power is Provisional without a dated metagame sample.
