Gravekeeper's Deck #763336 — Yu-Gi-Oh! OCG

Deck — Deck Power Evaluation

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

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

Legality

Main 40 / Extra 1 / Side 0 — status under the rules at evaluation time: Illegal. 2 violation(s).

Identity & game plan

• Win condition: Board breakers and 3000-ATK beaters (Beast King Barbaros, Ancient Gear Gadjiltron Dragon) backed by Gravekeeper's pressure; Stardust Dragon as the only Extra Deck closer; Stardust Dragon protecting the board from destruction effects
• Turn 1 (going first): Open a Gravekeeper's starter (Commandant, Spy, Descendant) and search Necrovalley, then develop a board and hold Solemn Judgment or Mirror Force; the list has no hand-trap starter, so the opening rests on archetype density
• Turn 2 (going second): Use Torrential Tribute, Mirror Force, Magic Cylinder and Sakuretsu Armor to stop the opponent's first board, then follow with Barbaros or Gadjiltron. This plan depends on hand quality, not on a reliable engine
• Recovery: Mostly recursion-free: Commandant and Descendant reload the hand only through the search effect, and the Heavy Storm / Skill Drain / Solemn package has no recovery of its own
• After siding: Not evaluable: the deck has no side deck (0 cards), so no post-side plan exists

Why it scores here

The deck is evaluated as a connected system, not as an average of its card scores. Its reliable part is the Gravekeeper's core: 13 exact-name copies, with P(at least one archetype-core card in a 5-card opening hand) of about 0.82 (Inferred), so it usually has a starter. Its weak part is coherence: only 31.7% exact-name purity, with Ancient Gear, Barbaros, Book of, and generic cards filling 28 of 41 slots, and no combo boards recorded, so conversion and median output are text-only inferences. Interaction is the strongest area (about 14 negation, removal, or floodgate effects, including Solemn Judgment, Heavy Storm, and Mirror Force), but it is spread across overlapping and partly redundant pieces. The list is illegal (Terraforming and Skill Drain each run 2 copies against a limit of 1), so it cannot receive a normal Final score and is capped low. Popularity did not earn points: the archetype appears in the usage stats, but that confirms the list is real rather than strong.

Dimension scores

How the score was computed

Strategy profile: Toolbox. Structural ≈ 43, Going First ≈ 45, Going Second ≈ 42, Meta = provisional, Tournament Reliability ≈ 35. Modifiers: banlist_exposure (-8); no_side_deck (-3). Final formula: 0.80*Structural + 0.20*TournamentReliability + ContextModifiers, capped low because the deck is Illegal (Meta provisional)

Probability & combo summary

• Opening a starter: P(≥1) ≈ 0.82 · 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

• Archetype core of 13 exact copies gives about 0.82 chance of a starter in a 5-card opening hand
• Broad interaction suite (about 14 negate, removal, or floodgate effects)
• Two 3000-ATK closers plus Stardust Dragon as a resilient Extra Deck threat

Weaknesses

• Illegal: Terraforming and Skill Drain each run 2 copies against a limit of 1
• Only 31.7% exact archetype purity; off-archetype filler dilutes the engine
• No side deck, so no best-of-3 adaptation
• Single Extra Deck card and no recorded combo boards

Critical choke points

• Necrovalley and the Gravekeeper's bodies are the only engine pieces, so losing them to interaction removes most of the plan
• Stardust Dragon is the only Extra Deck threat and the only resilient answer to destruction

Recommended changes

Evidence & confidence

• Verified: Deck is Illegal: Terraforming and Skill Drain each run 2 copies against an OCG limit of 1; Main 40, Extra 1, Side 0; size is within OCG rules; Card texts for Commandant, Descendant, Necrovalley, Stardust Dragon, Barbaros, Gadjiltron Dragon
• Inferred: P(at least one archetype-core card in hand5) about 0.82 from the hypergeometric table; Interaction density of about 14 effects from the role-tag counts; Conversion, floor and median output estimated from text alone (no combos)
• Provisional: Meta Power and matchup fit: no dated metagame or 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 record absent no win-rate telemetry for going-first/second, matchup, or brick rate Meta Power is Provisional unless a dated metagame sample is supplied no side deck supplied, so post-side performance cannot be assessed
