Gravekeeper's Deck #686162 — Yu-Gi-Oh! OCG

Deck — Deck Power Evaluation

Final Contextual Deck Power: 29/100 (±6 · Confidence: Low)

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

Legality

Main 43 / Extra 17 / Side 0 — status: Illegal. 2 violation(s).

Identity & game plan

• Win condition: Xyz/Train boss beats (Superdreadnought Rail Cannon Gustav Max direct damage, Gustav Rocket 5000 ATK, Liebe 4000 ATK) after Gravekeeper's Commandant and Necrovalley setup; Crystal Beast / Timelord / Malefic board pressure with Rainbow Dark Dragon and Sandaion
• Turn 1 (going first): Open a searcher (Commandant, Eldlich, Throne, Terraforming, Pot of Prosperity) and build a Gravekeeper's/Necrovalley field, then Xyz into a Train or Time Thief boss; Foolish Burial Goods supplies a second spell/trap
• Turn 2 (going second): Use Feather Duster, Skill Drain and Rainbow Dragon to strip or negate the opponent's board, then rebuild with Commandant and Necrovalley; no hand traps are present to force the opening
• Recovery: Commandant, Eldlich and Necrovalley Throne recover monsters and spells from the Deck; Time Thief Redoer and Diamond Dire Wolf give extra removal and draw
• After siding: No side deck: no post-side plan exists in the list

Why it scores here

This list is illegal as built: the Extra Deck holds 17 cards against an OCG limit of 15, so under the rubric it receives a capped, structural-only read. Structurally it is a toolbox of three or more unrelated engines (Gravekeeper's/Necrovalley, Train, Crystal Beast, Timelord, Malefic, Exodia and Azamina pieces) with only 9 exact-name Gravekeeper's copies (15% exact-name purity) and none of the archetype's 16 standard core staples present, so the score comes from consistency and closing power on the system rather than from the strength of individual cards or the archetype's popularity. Starter access is moderate (about 32% per copy-3 starter in a 5-card hand) but 12 searcher copies give about 82% of at least one searcher in hand, which carries the consistency read. Interaction is thin and scattered (Feather Duster, Skill Drain, Rainbow Dragon, Necrovalley negation text) with no hand traps, and the deck has no side plan. Meta is provisional with no tournament, combo or win-rate data, so the score rests on text and probability inference, and it is not an average of card scores.

Dimension scores

How the score was computed

Strategy profile: Toolbox. Structural ≈ 39, Going First ≈ 40, Going Second ≈ 36, Meta = provisional, Tournament Reliability ≈ 35. Modifiers: Engine conflicts (-6); No post-side plan (-3). Final formula: 0.80*Structural(39) + 0.20*TournamentReliability(35) + ContextModifiers(-9) = 29; Meta provisional; illegal Extra Deck size, so structural-only read

Probability & combo summary

• Opening a starter: P(≥1) ≈ 0.32 · 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: 12 searcher-text copies give about 82% of at least one searcher in a 5-card hand (Verified probability)
• Multiple closing options: Gustav Max direct damage, Gustav Rocket 5000 ATK, Liebe and Dora give Extra-Deck pressure (Verified stats)
• Layered recovery through Commandant, Eldlich and Necrovalley Throne, plus two Foolish Burial Goods (Inferred from text)

Weaknesses

• Illegal as built: Extra Deck 17 vs limit 15
• Weak archetype identity: 15% exact-name purity and 0 of 16 core staples (Verified)
• Dead or near-dead Extra-Deck cards: Exodia Incarnate (no Forbidden One), Saint Azamina (no Synchro), Cyber End Dragon (no Cyber Dragons) (Inferred from the card list)
• No hand traps and no side deck

Critical choke points

• Necrovalley negation and Gravekeeper's field requirement: the GY-protection plan fails if no Gravekeeper's monster is on the field
• Commandant/Eldlich as the only reliable starters, each at about 32% per copy-3 opening hand

Recommended changes

Evidence & confidence

• Verified: Extra Deck 17 vs OCG max 15 (size violation); Copy limits pass for all restricted cards (Limited 1, Semi-Limited 2); Searcher probability 0.8235 and copy-3 starter probability 0.3164 (hypergeometric); 0 of 16 usage-stat core cards present
• Inferred: Engine conflicts across Gravekeeper's, Train, Crystal Beast, Timelord, Malefic and Exodia/Azamina; Dead Extra-Deck cards: Exodia Incarnate, Saint Azamina, Cyber End Dragon; Consistency and brick-rate estimates from text plus probability; Interaction quality from text (Duster, Skill Drain, Rainbow Dragon, Necrovalley)
• Provisional: Meta Power (no dated metagame sample); Matchup and format fit (D13); Going-second split and post-side performance
• 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 absent no win-rate telemetry (going-first/second, matchup, brick/starter/OTK rates) Meta Power is Provisional unless a dated metagame sample is supplied Deck title is null; the evaluation uses the archetype name
