Harpie Deck #769629 — Yu-Gi-Oh! OCG

Deck — Deck Power Evaluation

Final Contextual Deck Power: 20/100 (±8 · Confidence: Low)

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

Legality

Main 56 / Extra 16 / Side 0 — status: Illegal. 5 violation(s).

Identity & game plan

• Win condition: Synchro and Link boss monsters (Clear Wing Synchro Dragon line, Crystal Clear Wing Over Synchro Dragon, Hi-Speedroid Kitedrake) built from a Speedroid/Roid engine. Structural read only, because the list is illegal.; Harpie Lady - Elegant Egotist and Clear Wing recursion to keep pressure on after a disruption.
• Turn 1 (going first): Open a Speedroid or Roid starter (Terrortop, Taketomborg, Marble Machine, CarTurbo or Colonel Clackers), search a second Speedroid, and Synchro into a boss with hand traps held up.
• Turn 2 (going second): Use the 9 hand traps (Ash Blossom, Ghost Belle, Maxx C, Droll & Lock Bird, Infinite Impermanence, Synchro Emergency, Dominus Purge, Crossout Designator, Feather Duster) to answer the opponent's first board, then rebuild through the GY-banish Speedroid effects.
• Recovery: Recover through Speedroid Den-Den Daiko Duke and CarTurbo banishing from the GY, Speedroid Scratch and Speedroid Dupligate recursion, and Maxx C draw.
• After siding: Not evaluable. The Side Deck is empty, so there is no post-side plan.

Why it scores here

The deck is scored as a system on its Speedroid/Roid starter density, hand-trap redundancy (9 hand traps and tech cards), and Clear Wing/Hi-Speedroid Synchro boss access, not as an average of card scores. Starter accessibility is moderate: several 3-copy Speedroid starters and the 9 searcher-text cards give a reasonable chance of a live engine by turn 2 (Inferred), but the 56-card main deck with 28 distinct cards and a 0-card Side Deck costs consistency. Interaction is the strongest area: the hand-trap package and layered Synchro effects give real going-second resilience. Combo conversion and floor/median are scored low because no recorded boards exist, so these are text-only inference. The deck is Illegal (3 Forbidden cards and an over-sized Extra Deck), so the final score is capped at 20 and the evaluation is structural-only. Archetype popularity earned no points, since there is no tournament link and usage stats cover only two tech cards.

Dimension scores

How the score was computed

Strategy profile: Midrange primary, Balanced secondary (structural only). Structural ≈ 50, Going First ≈ 50, Going Second ≈ 58, Meta = provisional, Tournament Reliability ≈ 40. Modifiers: banlist exposure (-6); extra deck overflow (-2); no side deck (-2). Final formula: Pre-cap: 0.80*Structural(50.4) + 0.20*TournamentReliability(40) + Modifiers(-10) = 38.3; Illegal-deck cap applied: final = 20 (theoretical / structural-only). Meta Power provisional.

Probability & combo summary

• Opening a starter: P(≥1) ≈ 0.6 · 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 hand-trap package (9 cards) with redundant negation and disruption
• Multiple 3-copy Speedroid starters give engine redundancy
• Strong Synchro boss options with layered negation

Weaknesses

• Illegal in OCG: 3 Forbidden cards run and Extra Deck is over-sized
• Very low exact-archetype purity (5.6%) and heavy off-theme slots
• Empty Side Deck removes any post-side plan
• No recorded combos, so ceiling and median are text-only

Critical choke points

• Speedroid starter (Terrortop, Taketomborg, Marble Machine, CarTurbo or Clackers) in the opening hand
• Forbidden Synchro bosses (Crystal Wing, Baronne, Auroradon) that the deck relies on for its boss slots

Recommended changes

Evidence & confidence

• Verified: Illegal status: 3 Forbidden cards run, Extra Deck 16 > 15; Main Deck 56 cards within the 40-60 OCG range; Side Deck is 0 cards; Card text for the 9 hand traps and 9 searcher-text cards; Usage stats: Droll & Lock Bird 69.2%, Harpie's Feather Duster 61.5%
• Inferred: Starter accessibility ~0.60 from hypergeometric searcher-text estimate; Interaction density and hand-trap value (going-second strength); Dimension scores built from text and composition
• Provisional: Meta Power (no dated metagame sample); Matchup fit (no tournament link)
• 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 (going-first/second, matchup, brick/starter rates) Meta Power is Provisional unless a dated metagame sample is supplied usage statistics cover only two tech cards
