Harpie Deck #769190 — Yu-Gi-Oh! OCG

Deck — Deck Power Evaluation

Final Contextual Deck Power: 54/100 (±8 · Confidence: Medium)

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

Legality

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

Identity & game plan

• Win condition: Chain Harpie Lady-named and Harpie monsters into Extra Deck Synchro, Xyz and Link summons (Cyber Slash Harpie Lady x2, Raidraptor, Tri-Brigade Shuraig, Divine Arsenal) and close with 2600-3000 ATK bodies.; Hysteric Party mass-summons Harpie Lady copies from the GY for a board-based mass attack.
• Turn 1 (going first): Open with a level 4 WIND Harpie (Pet Dragon, Perfumer, Harpist, Oracle or Channeler) to reach a Harpie Lady-named body, then extend into Extra Deck summons.
• Turn 2 (going second): Hand traps (Ash Blossom x2, Droll & Lock Bird) and Forbidden Droplet to stop the opponent's first board, then rebuild Harpie Lady from the GY or deck.
• Recovery: Recur Harpie Lady-named monsters from the GY with Harpie's Feather Rest and Hysteric Party, and search Harpie Lady Elegance or Hysteric Sign for the next wave.
• After siding: Not applicable: the deck registers zero side cards, so there is no post-side plan.

Why it scores here

The deck reliably opens a functional starter: 15 copies of level 4 or lower WIND Harpie starters (Pet Dragon, Perfumer, Harpist, Oracle, Channeler) give about a 92% chance of at least one starter in an opening 5 (Inferred hypergeometric). The live engine is narrower, since only 3 Harpie Lady-named cards (Harpie Lady 1 x2, Cyber Harpie Lady) are in the deck, giving about a 34% chance of one in an opening 5, and Harpie Lady Sisters is absent so Perfumer and Elegant Egotist lose part of their intended lines. Conversion into the Extra Deck is the main value, with two Cyber Slash Harpie Lady, a Raidraptor, a Tri-Brigade Shuraig and several 3000-ATK closers, but no recorded boards exist so the ceiling and median are text-only inference. Interaction is layered but thin: two Ash Blossom, one Droll & Lock Bird, Forbidden Droplet x3 and single-copy Feather Duster, with no side deck to adapt after game 1. Popularity and the archetype usage stats confirm a real, accessible list but did not earn points on their own, and card scores were not averaged into the deck score.

Dimension scores

How the score was computed

Strategy profile: Combo. Structural ≈ 61, Going First ≈ 62, Going Second ≈ 58, Meta = provisional, Tournament Reliability ≈ 52. Modifiers: Banlist exposure (-1); No side deck (-2); Harpie Lady Sisters absent (-2). Final formula: 0.80*Structural + 0.20*TournamentReliability + ContextModifiers (Meta provisional): 0.80*61 + 0.20*52 = 59.2, then -5 modifiers = 54

Probability & combo summary

• Opening a starter: P(≥1) ≈ 0.92 · 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

• Many overlapping level 4 WIND Harpie starters give high access to a live board on turn 1
• Multiple 2600-3000 ATK Extra Deck closers across Synchro, Xyz and Link
• Three hand traps plus Forbidden Droplet give going-second interaction
• Legal and fully resolved list with no size violations

Weaknesses

• No side deck, so no adaptation after game 1
• Harpie Lady Sisters is absent, weakening Perfumer and Egotist lines
• Only 3 Harpie Lady-named cards, so the Lady-live engine is inconsistent
• Off-archetype copies (21 of 40 main) dilute the engine
• No recorded boards, so the ceiling and median are inferred from text only

Critical choke points

• Getting a Harpie Lady-named monster on the field early, since most Lady-dependent lines need one
• Surviving a single hand trap or Droplet-blocked turn without a second engine route

• Provisional: Meta and matchup fit (no tournament or meta-share data)
• 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, going-second, matchup and brick rates are Inferred or Unknown Meta Power is Provisional unless a dated metagame sample is supplied No side deck registered, so no post-side evidence
