Legality

Main 42 / Extra 15 / Side 0 — status: Legal. Restricted cards run: Foolish Burial Goods (Limited), Harpie's Feather Duster (Limited), Maxx "C" (Limited).

Identity & game plan

  • Win condition: OTK via Harpie + Obelisk the Tormentor + Rank-Up
  • Turn 1 (going first): Set 2-3 backrow (Walls of the Imperial Tomb/Soul Crossing), open with Soul Crossing/Soul Exchange to search Obelisk, then combo into Rank-Up OTK
  • Turn 2 (going second): Survive Turn 1, answer early threats, then use hand-trap Maxx "C" and counter disruption to stabilize and go for OTK
  • Recovery: Rank-Up recursion through Foolish Burial Goods + Soul Exchange to re-summon Obelisk/Imsety and continue combo

Why it scores here

The deck reliably opens to a functional plan (OTK via Harpie/Obelisk/Rank-Up) with strong ceiling (D3 80) but suffers from brick risk and inconsistency (D1 65, D2 55), leading to a median output around 50 (D4). It shows solid disruption and end-board presence (D7 70) and decent offensive pressure (D9 75), yet struggles with going-second stability (D8 50), side adaptability (D12 30), and format fit (D13 40), producing a mid-tier consistent combo score around 60.

How the score was computed

Structural ≈ 60, Going First ≈ 65, Going Second ≈ 50, Meta = provisional, Tournament Reliability ≈ 50. Modifiers: none. Final formula: 0.80*Structural + 0.20*TournamentReliability (Meta provisional)

Probability & combo summary

  • Opening a starter: P(≥1) ≈ — · key two-card combo ≈ — · full-brick estimate ≈ 0.68 (all Inferred)
  • Combo output: best PowerIndex 80, median 50, board-per-starter 2.6
  • Turn order: 0 going-first lines vs 0 going-second lines

Strengths

  • Strong ceiling with Obelisk the Tormentor + Harpie + Rank-Up OTK
  • Solid disruption suite (Negate, removal, backrow)
  • Good end-board presence and offensive pressure

Weaknesses

  • High brick rate (~68% Turn 1 proxy-brick without Obelisk)
  • Inconsistent searcher efficiency and extra deck reliance
  • Vulnerable to targeted hand-trap disruption and format meta shifts

Critical choke points

  • Dependence on Obelisk the Tormentor surviving Turn 1
  • Limited going-second plan and board-breaker redundancy
  • No side deck included for adaptation
Priority Remove Add Reason
1 Maxx "C" (1) to reduce brick and streamline consistency Add 1-2 additional Harpie searchers (e.g., "Harpie's Interception" or similar) Lower brick rate and improve Turn 1 engine reliability
2 Harpie's Feather Duster (1) if format penalizes heavy Spell/Trap destruction Add 1 hand-trap or counter to preserve disruption vs targeted meta Maintain interaction quality against prevalent disruption

Evidence & confidence

  • Verified: Harpie's Feather Duster banlist status; Obelisk the Tormentor effect text; Deck size 42/15
  • Observed: Best line OTK sequence; Extra-Deck composition
  • Inferred: Turn 1 consistency probabilities; Median power index; Going-second breaker analysis
  • Provisional: Meta power; Tournament reliability; Format fit
