Harpie Deck #769373 — Yu-Gi-Oh! OCG

Deck — Deck Power Evaluation

Final Contextual Deck Power: 31/100 (±8 · Confidence: Low)

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

Legality

Main 60 / Extra 15 / Side 0 — status under the rules at evaluation time: Illegal. 3 violation(s).

Identity & game plan

• Win condition: Tri-Brigade and Radiant Typhoon Link/Synchro boards built from Beast, Beast-Warrior and Winged Beast monsters, with Cyber Slash Harpie Lady and Tri-Brigade Shuraig/Arms Bucephalus II as the big-body closers (text-only read, Inferred); Harpie Lady / Cyber Slash Harpie Lady synchro pressure, with Tempest and Mist Valley Apex Avian as flexible WIND beaters (Inferred)
• Turn 1 (going first): Open on Radiant Typhoon searchers (Eldam/Swen/Vision/Chant) and Primite Lordly Lode or Tri-Brigade Hammer to convert a card into a Link or Synchro starter, then keep Ash Blossom and Droll & Lock Bird up as interaction (Inferred)
• Turn 2 (going second): Hold Ash Blossom, Droll & Lock Bird and Maxx C as hand traps for the opponent's first search or Special Summon, then rebuild through Tri-Brigade Kitt/Kerass and the Tri-Brigade Link engine (Inferred)
• Recovery: Recover through Tri-Brigade Revolt and Tri-Brigade Roar from the GY, and Tri-Brigade Hammer/Oath banish-and-summon effects for Link Summons (Inferred, text only)
• After siding: No side deck is registered, so there is no post-side plan; the deck cannot adapt between games in a best-of-3 (verified from export)

Why it scores here

This 60/15 list runs a mixed toolbox of three to four partial engines (Radiant Typhoon, Tri-Brigade, Primite and Harpie), and its exact-archetype purity is only 8%, so the engines compete for the same hand slots rather than reinforcing each other. Starter access is reasonable on paper: the searcher-text group reaches P(at least one in a 5-card opening hand) ≈ 0.95, and the three-copy staples have P ≈ 0.23 each, which is an Inferred hypergeometric estimate. The hand-trap suite (Ash Blossom, Droll & Lock Bird, Maxx C, plus Ash in two copies) gives the deck interaction for going second, but there are no recorded boards, so ceiling and floor cannot be measured and the combo dimensions rest on text reads only. The deck is Illegal in OCG: it runs one Forbidden Simorgh and two copies of the Limited Radiant Typhoon Chant, so under the rubric it is scored structurally/theoretically only and capped low; the 31 reflects that cap plus banlist exposure and engine conflicts, not an average of card scores or the popularity of the Harpie or Tri-Brigade names. Meta power is null because no dated metagame sample was supplied.

Dimension scores

How the score was computed

Strategy profile: Midrange primary, Toolbox secondary; Structural weights = Midrange profile (D1 11, D2 7, D3 7, D4 9, D5 12, D6 12, D7 9, D8 8, D9 5, D10 6, D11 3, D12 4, D13 5, D14 2). Structural ≈ 43, Going First ≈ 42, Going Second ≈ 38, Meta = provisional, Tournament Reliability ≈ 40. Modifiers: banlist exposure (-8); engine conflicts (-4). Final formula: 0.80*Structural + 0.20*TournamentReliability (Meta provisional) = 0.80*43.3 + 0.20*40 = 42.6, then context modifiers -12 and Illegal cap applied; rounded to 31

Probability & combo summary

• Opening a starter: P(≥1) ≈ 0.95 · 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 (26 cards) gives high opening-hand starter access (Inferred)
• Four hand traps plus several negation/removal effects give layered interaction (Inferred)
• Full Extra Deck (15/15) with a broad Link base (Verified count)

Weaknesses

• Illegal in OCG: Forbidden Simorgh and two Limited-copy violation on Radiant Typhoon Chant (Verified)
• Mixed engines with 8% exact-archetype purity (Verified count)
• No side deck, so no post-side adaptability (Verified)
• No recorded boards, so ceiling and floor are not measurable (Verified absence)

Critical choke points

• Simorgh is illegal, so any line that depends on it cannot be run in OCG
• Over-limit Radiant Typhoon Chant makes one copy a forced cut
• Single-copy Link enablers such as Bucephalus II, Shuraig and Cyber Slash Harpie Lady are the closers and not redundant

Recommended changes

Evidence & confidence

• Verified: Main 60, Extra 15, Side 0 (within OCG size rules); Forbidden: Simorgh run at 1 copy (0 legal); Limited: Radiant Typhoon Chant run at 2 copies (1 legal); Maxx C, Droll & Lock Bird, Yummy Snatchy each run at 1 (legal); Exact archetype purity 8%; 69 off-archetype copies; 26 searcher-text cards
• Inferred: Opening-hand starter access ≈ 0.95 (searcher group, hypergeometric); Interaction density from hand-trap and negation text roles; Engine split across Radiant Typhoon, Tri-Brigade, Primite and Harpie; Going-first and going-second plans from card text
• Provisional: Meta Power (null) and matchup fit (D13) — no dated metagame sample or tournament link
• Data gaps: No combos supplied: combo floor, median and ceiling are text-only inference No tournament link: archetype meta-share and per-pilot record absent No win-rate telemetry exists in YGOVN (going-first/second, matchup, brick/starter rates) Meta Power is Provisional unless a dated metagame sample is supplied Side deck is empty, so post-side plan and D12 cannot be measured Deck title is null; archetype label 'Harpie' does not match the majority of the list (Tri-Brigade/Radiant Typhoon/Primite)
