Harpie Deck #775076 — Yu-Gi-Oh! OCG

Deck — Deck Power Evaluation

Final Contextual Deck Power: 35/100 (±8 · Confidence: Low)

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

Legality

Main 53 / Extra 17 / Side 0 — status under the rules at evaluation time: Illegal. 4 violation(s).

Identity & game plan

• Win condition: Train-engine Xyz beatdown: Superdreadnought Rail Cannon Gustav Rocket (5000 ATK), Juggernaut Liebe (4000 ATK) and Flying Launcher (3800 ATK) built through Train searchers and Night Train Blue Traveler / Super Express Bullet Train; Mulcharmy and Infinitrack draw and recursion engines that grind card advantage before the Xyz finish
• Turn 1 (going first): Open a Train or Infinitrack searcher (about 0.89 for at least one of 18 searcher-text cards in a 5-card hand), search an EARTH Machine engine, then Normal Summon into Xyz material such as Heavy Freight Train Derricrane or Infinitrack Anchor Drill for a Level 10 or Level 5 Xyz. Mulcharmy draw effects need an empty field and are unreliable at this stage
• Turn 2 (going second): Use the four hand traps (Ash Blossom and Joyous Spring, Maxx C, Droll and Lock Bird, Ghost Sister and Spooky Dogwood) to stop the opponent's board, then rebuild with Xyz or Link summons from the Extra Deck. No side deck is available for this
• Recovery: Train recursion (Night Train Blue Traveler and Derricrane from the GY, Revolving Switchyard) and Infinitrack banish-from-GY effects provide several routes back to a Level 10 or Level 5 board after a single disruption
• After siding: Not applicable: the deck has 0 side cards, so there is no post-side plan. A best-of-3 event would need a side deck built from scratch

Why it scores here

The deck can usually open a live engine: about 0.89 of 5-card opening hands contain at least one of its 18 searcher-text cards, so the Train and Infinitrack lines start on turn 1 in most games (Inferred). Its ceiling is high because several Level 10 and Level 5 Xyz monsters reach 3800 to 5000 ATK, and the Train recursion gives several routes back to a Level 10 board after one disruption (Inferred). The four hand traps and about 10 negation-text cards give it a real interaction layer, but the 0 side cards and the illegal list cap the score. No combo recordings or win-rate data were supplied, so median output and matchup fit are inferred from card text rather than measured. The score comes from the deck as a system (engine access, interaction, closing power) and not from averaging card scores or from the archetype's popularity.

Dimension scores

How the score was computed

Strategy profile: Midrange primary, Toolbox secondary (disclosed; weights taken from the Midrange profile). Structural ≈ 54, Going First ≈ 60, Going Second ≈ 55, Meta = provisional, Tournament Reliability ≈ 48. Modifiers: banlist exposure (-10); extra-deck size violation (-2); illegal cap (-5). Final formula: Structural 53.8 from the Midrange profile; 0.80*Structural + 0.20*TournamentReliability + modifiers = 40.8, then capped at 35 because the list is Illegal. Theoretical / structural-only; Meta Power is provisional (null).

Probability & combo summary

• Opening a starter: P(≥1) ≈ 0.89 · 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

• Searcher density: 18 searcher-text cards give about 0.89 chance of a starter in a 5-card hand
• High-ATK Xyz finishers (Gustav Rocket 5000, Liebe 4000, Flying Launcher 3800)
• Four hand traps and about 10 negation-text cards give layered interaction
• Train and Infinitrack recursion gives several routes to rebuild after disruption

Weaknesses

• Illegal list: 17-card Extra Deck, 3 copies of a Limited card, and 2 Forbidden cards
• Archetype label Harpie does not match the contents (Train / Infinitrack / Mulcharmy)
• No side deck, so no post-side adaptation
• Many singletons and Level 0 spells make the main deck hard to keep consistent
• No combo or tournament data to confirm the deck's real output

Critical choke points

• Forbidden Varudras and Kashtira Arise-Heart must be removed before the list can be played
• Gustav Max over the Limited cap: 3 copies must drop to 1
• Extra Deck must lose 2 cards to reach the 15-card limit

Recommended changes

Evidence & confidence

• Verified: Legality: main 53, Extra 17 (over 15), side 0; Gustav Max 3 copies vs Limited 1; Kashtira Arise-Heart and Varudras Forbidden; Card text and stats for every listed card, from the resolved card list; Searcher-text count 18, negation-text 10, removal-text 15, hand traps 4 (role tags from the export)
• Inferred: Opening-hand consistency (P = 0.887 for at least one searcher in 5 cards; hypergeometric); Functional role and engine coherence of the Train, Infinitrack and Mulcharmy lines; Closing power and interaction strength, read from stats and card text; Going-second hand-trap estimate (P = 0.391 for at least one hand trap in 6 cards)
• Provisional: Meta Power (null; no dated metagame sample); Matchup fit (D13) and tournament reliability (no 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 match record are absent No win-rate telemetry (going-first/second, matchup, brick and starter rates) Meta Power is Provisional unless a dated metagame sample is supplied Archetype label 'Harpie' does not match the deck's contents (Train / Infinitrack / Mulcharmy); the label should be checked in the database Title is null in the deck export
