Legality

Main 55 / Extra 0 / Side 0 — status under the rules at evaluation time: Illegal. 5 violation(s).

Identity & game plan

  • Win condition: Gravekeeper's monster beatdown under Necrovalley, with Gravekeeper's Spear Soldier piercing and Assailant redirecting attacks; Board control via Mirror Force, Torrential Tribute, Dust Tornado, and Ring of Destruction, then closing with whatever survives
  • Turn 1 (going first): Open Gravekeeper's Spy or Royal Tribute with Necrovalley, set interaction, and keep Solemn Judgment or Skill Drain up while the Spy flips into a Gravekeeper's body
  • Turn 2 (going second): Use hand-based Gravekeeper's bodies plus Mirror Force and Torrential Tribute to answer the first board, then rebuild with Rite of Spirit recursion
  • Recovery: Rite of Spirit to return Gravekeeper's from the GY, with Necrovalley keeping the Graveyard stable; the Main Deck has few draw or search effects to fill gaps
  • After siding: No side deck is registered, so no post-side plan is evaluable; the list is theoretical only

Why it scores here

The deck opens reliably on its archetype core: 19 Gravekeeper's copies give about 0.89 probability of at least one in a five-card opening hand (Inferred hypergeometric estimate), so the engine is usually live on turn one. Conversion is weak, because no recorded boards exist and the text-only read shows a loose, low-density engine with 31% exact-archetype purity across 37 distinct cards. Interaction is the main strength, with Mirror Force, Torrential Tribute, Dust Tornado, Ring of Destruction, and Necrovalley providing layered answers, but three Forbidden cards and two over-limit Limited cards make the list illegal in OCG, which caps the score. The score comes from consistency and interaction on the system, not from the archetype's popularity or from averaging the card scores.

Dimension scores

# Dimension Score Evidence
D1 Engine Accessibility & Consistency 58 P(at least one archetype-core card in a 5-card opener) ≈ 0.89 over 19 copies; the individual starters are thin at ≈0.25 for the 3-copy Spy (Inferred)
D2 Opening-Hand Quality & Brick Management 50 Proxy brick rate ≈ 0.11 for the core group; 24 singleton slots and 38 off-archetype copies raise the risk of dead non-engine hands (Inferred)
D3 Combo Conversion & Ceiling 35 No parseable recorded boards; ceiling is a text-only read of Spy→Assailant/Guard bodies with Royal Tribute and Necrovalley (Inferred)
D4 Combo Floor & Median Output 30 No recorded boards, so no median or power distribution exists; the typical line is inferred to be a single Gravekeeper's body (Inferred)
D5 Interruption Resilience & Route Redundancy 45 Recursion via Rite of Spirit and two-plus interaction options give partial redundancy, but no independent-line data exists (Inferred)
D6 Resource Economy, Recovery & Grind 40 Little draw or search and limited recycling; Graceful Charity and Pot of Greed are Forbidden and cannot be run (Inferred)
D7 End-Board & Interaction Quality 60 21 removal-text and 9 negation-text cards, with Mirror Force, Torrential Tribute, Ring of Destruction, and Necrovalley; Solemn and Skill Drain are over limit (Verified text, Inferred quality)
D8 Going-Second & Board-Breaking Power 55 Mirror Force, Torrential Tribute, Dust Tornado, and Ring of Destruction answer a going-second board; no split data exists (Inferred)
D9 Offensive Pressure & Closing Power 40 Spear Soldier pierces and Assailant redirects attacks, but there are no end-board ATK or boss-monster data (Inferred)
D10 Main Deck Efficiency & Flexibility 45 55 Main cards in the legal 40–60 range, 37 distinct cards, and 31% exact-name archetype purity; there are many generic staples (Verified composition)
D11 Extra Deck Efficiency & Coverage 35 No Extra Deck is registered; the archetype does not need one, so the score is neutral-low for flexibility (Verified)
D12 Side Deck Adaptability 20 No Side Deck is registered, so no post-side adaptability can be assessed (Verified gap)
D13 Matchup Coverage & Format Fit 40 No tournament link or dated meta sample; Meta Power is Provisional and this dimension is low-confidence (Provisional)
D14 Pilotability & Error Tolerance 55 Multi-step Necrovalley and Gravekeeper's sequencing with several flip and summon decisions, but short turns and clear card roles (Inferred)

How the score was computed

Strategy profile: Control 85 / Stun 15 (approximate). Structural ≈ 45, Going First ≈ 44, Going Second ≈ 47, Meta = provisional, Tournament Reliability ≈ 40. Modifiers: banlist exposure (-8); no side deck (-5); illegal-list cap (-6). Final formula: No reliable metagame: 0.80*Structural(45) + 0.20*TournamentReliability(40) = 44 before modifiers; modifiers -13 gives 31; Illegal cap sets final to 25

Probability & combo summary

  • Opening a starter: P(≥1) ≈ 0.89 · key two-card combo ≈ — · full-brick estimate ≈ 0.11 (all Inferred)
  • Combo output: best PowerIndex —, median —, board-per-starter —
  • Turn order: 0 going-first lines vs 0 going-second lines

Strengths

  • Archetype core present at 19 copies with high opener access (Inferred)
  • Layered interaction: Mirror Force, Torrential Tribute, Dust Tornado, Ring of Destruction, Necrovalley (Verified text)
  • Usage stats show 93% of the archetype-standard core present (Observed)

Weaknesses

  • Illegal in OCG: 3 Forbidden cards and 2 over-limit Limited cards (Verified)
  • No combo evidence: ceiling and median are text-only inference (Inferred)
  • No side deck and no Extra Deck: no post-side plan and little flexibility (Verified)
  • Low exact-archetype purity at 31%, with many generic staples (Verified)

Critical choke points

  • Necrovalley and the Gravekeeper's Spy flip carry most lines; if they are dead, the Graveyard plan has no fallback (Inferred)
  • Forbidden and Limited cards removed from the Main Deck would shrink the deck to fewer than 55 legal cards and change the opening odds (Inferred)
Priority Remove Add Reason
1 Pot of Greed, Graceful Charity, Delinquent Duo Legal Gravekeeper's staples or a Limited-legal searcher at 1 copy Clears the Forbidden violations so the list is legal in OCG
2 One Solemn Judgment and one Skill Drain Non-Limited interaction or a Gravekeeper's body Brings the Limited cards to the legal single-copy cap
3 Off-archetype generic staples Gravekeeper's monsters or spells Raises exact-archetype purity from 31% and improves the engine
4 None A 10–15 card side deck Creates a post-side plan and adds adaptability, which is currently absent

Evidence & confidence

  • Verified: Legality: 3 Forbidden copies and 5 over-limit Limited copies; Composition: 55 Main, 0 Extra, 0 Side, 37 distinct cards; Card text for Necrovalley, Mirror Force, Torrential Tribute, Dust Tornado, Ring of Destruction, Rite of Spirit
  • Observed: Usage stats: 14 of 15 core cards present (93%)
  • Inferred: Opening access to the archetype core ≈ 0.89 (hypergeometric); Interaction density and going-second board answers from card text; Recovery and resilience from Rite of Spirit and Spear Soldier text
  • Provisional: Meta Power: no dated metagame sample; no tournament link; Matchup coverage (D13)
  • Data gaps: No combos supplied: combo floor, median, and ceiling are text-only inference No tournament link: archetype meta-share and per-pilot record absent No side deck registered: post-side adaptability cannot be scored No win-rate telemetry: going-first, going-second, and matchup rates are Unknown Meta Power is Provisional without a dated metagame sample Deck title is null
