Harpie Deck #758552 — Yu-Gi-Oh! OCG

Deck — Deck Power Evaluation

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

• Primary strategy: Midrange
• Secondary strategies: Tempo, Xyz/Synchro
• Format: ocg

Legality

Main 41 / Extra 15 / Side 0 — status: Legal.

Identity & game plan

• Win condition: Level 4 Xyz and Synchro bosses (Number C32: Shark Drake LeVeiss 3100 ATK, Number 69: Heraldry Crest - Dark Matter Demolition 3100 ATK, Cyber Slash Harpie Lady 2600 ATK) summoned from a board of Level 4 Harpie and Primite monsters; Harpie Lady name-change and Harpie Lady Synchro/Xyz bosses that negate or remove opposing cards
• Turn 1 (going first): Search with Hysteric Sign or Harpie Queen, then use Harpie Channeler, Harpie Perfumer or Harpie Harpist to build a Level 4 board and Xyz Summon a boss
• Turn 2 (going second): Hold Lost Wind, Quaking Mirror Force, Icarus Attack and Primite Drillbeam for the opponent's first board, then rebuild through the searchers and Level 4 Xyz bosses
• Recovery: Use Harpie Queen and Harpie Perfumer discard or Summon effects from the GY and Harpie's Pet Dragon to restock the board from hand, Deck or GY
• After siding: None: the deck runs an empty Side Deck, so there is no post-side plan

Why it scores here

The deck reliably opens a functional plan because 15 main-deck cards carry searcher text, giving roughly a 0.91 chance of at least one searcher in a 5-card opening hand (Inferred). Its conversion depends on Level 4 monsters feeding a 13-card Xyz and 2-card Synchro Extra Deck, and its boss stats (2600 to 3100 ATK) give it real closing power. Interaction comes from Extra Deck negations plus Lost Wind, Quaking Mirror Force, Icarus Attack and Primite Drillbeam, but it has no hand traps and no floodgates, so going second is weaker. Score is held back by a mixed build (exact-name purity 37.5%, 35 off-archetype copies across Primite, Heraldry, Number and Utopic), an empty Side Deck, and absence of two archetype-standard staples. Scoring is on the system; popularity was not credited and card scores were not averaged, and no combo or tournament data exists so the score rests on structure and text.

Dimension scores

How the score was computed

Strategy profile: Midrange. Structural ≈ 55, Going First ≈ 56, Going Second ≈ 50, Meta = provisional, Tournament Reliability ≈ 48. Modifiers: engine_conflicts (-4); no_side_deck (-2); search_redundancy (3). Final formula: 0.80*Structural + 0.20*TournamentReliability + ContextModifiers (Meta provisional, null)

Probability & combo summary

• Opening a starter: P(≥1) ≈ 0.91 · 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

• 15 searcher-text cards give high opening access to the engine (Inferred)
• Extra Deck bosses at 2600-3100 ATK give real closing power (Verified stats)
• Several negation and removal cards for both going-first and going-second interaction (Verified flags, Inferred semantics)
• Legal in OCG with no copy-limit violations (Verified)

Weaknesses

• Exact-name purity is 37.5% with 35 off-archetype copies across five sub-archetypes (Verified)
• Empty Side Deck, so there is no post-side plan (Verified)
• No hand traps or floodgates (Verified)
• Two archetype-standard staples are absent: Droll & Lock Bird (64.7% inclusion) and Harpie's Feather Duster (58.8%) (Verified usage stats)
• No combo boards and no tournament data, so the floor and median cannot be measured (Verified gap)

Critical choke points

• Level 4 monster count in hand and field (15 in main) gates most Xyz and Synchro summons (Inferred)
• Harpie Lady x2 is the name-change and Synchro-tuner hub, and only 0.23 of openings contain one (Inferred)
• Going second has no hand trap, so the first board relies on Lost Wind, Quaking Mirror Force and Icarus Attack (Inferred)

Recommended changes

Evidence & confidence

• Verified: Legal in OCG: 41 main, 15 extra, 0 side, no violations; 15 searcher-text cards and 4 negation / 8 removal text cards (role tags); Exact-name purity 37.5%; 35 off-archetype copies; Droll & Lock Bird (64.7%) and Harpie's Feather Duster (58.8%) are absent from the deck
• Inferred: P(at least one searcher in hand5) ~0.91 (hypergeometric); P(at least one Harpie Lady in hand5) ~0.23 (hypergeometric); Level 4 density supports the Xyz plan; engine conflicts lower consistency; Going-second interaction is limited without hand traps
• Provisional: Meta Power is null because no dated metagame sample is supplied; Matchup fit (D13) and tournament reliability depend on undated context
• 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 exists in YGOVN - going-first/second, matchup, brick and starter rates are Inferred or Unknown Meta Power is Provisional unless a dated metagame sample is supplied no side deck - post-side plan cannot be assessed
