Harpie Deck #773729 — Yu-Gi-Oh! TCG

Deck — Deck Power Evaluation

Final Contextual Deck Power: 30/100 (±8 · Confidence: Low)

• Primary strategy: Toolbox
• Secondary strategies: Stun, Midrange
• Format: tcg

Legality

Main 55 / Extra 15 / Side 0 — status under the rules at evaluation time: Illegal. 3 violation(s).

Identity & game plan

• Win condition: Fiendsmith and Evil Twin link/fusion boards, with Fiendsmith's Rextremende, Fiendsmith's Desirae and Evil★Twin's Trouble Sunny as the closers. Only inferred from card text; no combos were supplied.; Raigeki and Harpie's Feather Duster as non-engine board control, with Underworld Goddess and A Bao A Qu as large link boards.
• Turn 1 (going first): Open a starter (Live☆Twin Lil-la, Ki-sikil, or Effect Veiler) with the 3-copy hand traps held up for the opponent's first activation. Inferred from text.
• Turn 2 (going second): Hold 20 hand-trap and tech cards in the 6-card hand and answer the opponent's first summon or activation, then rebuild through the Fiendsmith and Live☆Twin searchers. Inferred from text.
• Recovery: Fiendsmith Engraver and Fiendsmith's Tract recover the Fiend line from the deck or GY, and Live☆Twin Sunny's Snitch and Secret Password refill the hand. Inferred from text.
• After siding: Not assessable. The deck has an empty Side Deck, so there is no post-side plan.

Why it scores here

This is a hand-trap and tech-heavy Harpie/Fiendsmith/Live☆Twin hybrid. Its consistency is the strongest part of the list: the archetype-core group has about 89% chance of at least one copy in a 5-card opening hand (Inferred). Interaction is dense, with 20 hand traps and 13 negation-text cards, and the deck is about 94% likely to hold at least one hand trap when going second (Inferred). Combo conversion, floor, and median could not be measured because no boards were supplied, so those scores are text-only inference. The score is not driven by Harpie's popularity, and card scores were not averaged. The list is illegal (three cards over their copy limits) and has no Side Deck, so the score is capped and labelled theoretical or structural-only.

Dimension scores

How the score was computed

Strategy profile: Toolbox primary, with Stun as a stated secondary; the blend uses the Toolbox weight profile only. Structural ≈ 51, Going First ≈ 58, Going Second ≈ 52, Meta = provisional, Tournament Reliability ≈ 40. Modifiers: Banlist exposure (over copy limits) (-8); Engine conflicts (-2). Final formula: No reliable metagame, so Meta is provisional: 0.80*Structural + 0.20*TournamentReliability + ContextModifiers = 0.80*51 + 0.20*40 - 10 = 38.8. The Illegal-list cap then sets the final score to 30 (theoretical/structural-only).

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

• Core starters are accessible: the archetype-core group has about 89% chance of at least one copy in a 5-card opening hand (Inferred).
• Dense interaction through 20 hand traps and 13 negation-text cards, with a going-second hand-trap chance of about 94% (Inferred).
• Strong Extra Deck closers at 3000 ATK and above, plus Fiendsmith recursion (Verified text).

Weaknesses

• Illegal list: three cards exceed their copy limits in TCG.
• Empty Side Deck, so no best-of-3 adaptation exists.
• Low archetype purity (1.4% exact name) and 69 off-archetype copies spread the engine across sub-archetypes.
• High brick risk from 22 tech and 20 hand-trap slots, with few guaranteed starters.

Critical choke points

• Ash Blossom, Fiendsmith Engraver, and Fiendsmith's Tract cannot all be run as listed, so the legal build changes the plan.
• Starter access depends on the Live☆Twin/Ki-sikil/Lil-la sequence; a missed first summon leaves the Fiendsmith line delayed.
• No Side Deck, so a single interruption on going-second can leave no plan.

Recommended changes

Evidence & confidence

• Verified: Legality: 55 Main, 15 Extra, 0 Side; three copy-limit violations (Ash ×3, Engraver ×3, Tract ×2).; Card text for the 28 Main and 15 Extra distinct cards, read from the excerpts.; Usage stats: all 8 core cards are present in the deck (100% core present).
• Inferred: P(≥1 core-group copy in opening 5) ≈ 0.89 and P(≥1 hand trap in going-second hand 6) ≈ 0.94.; Interaction density and brick risk from role-tag counts and card text.; Going-first and going-second plans from card text; no boards were supplied.
• Provisional: Meta Power (no dated metagame sample).; Matchup fit and tournament reliability (no tournament link).
• Data gaps: No combos supplied, so the floor, median, and ceiling are text-only inference. No tournament link, so archetype meta-share and per-pilot match records are absent. No win-rate telemetry for going-first, going-second, matchup, brick, or starter rates. Meta Power is provisional without a dated metagame sample. No Side Deck, so post-side performance cannot be scored.
