Gravekeeper's Deck #768748 — Yu-Gi-Oh! OCG

Deck — Deck Power Evaluation

Final Contextual Deck Power: 20/100 (±8 · Confidence: Medium)

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

Legality

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

Identity & game plan

• Win condition: Extra-Deck Fusion boards (King Dragun, Master of Oz, Gatling Dragon, Ojama King, Dark Blade) reached through generic searchers and draw; Direct attacks from Airknight Parshath and Reaper on the Nightmare after the board is cleared with Heavy Storm, Torrential Tribute or Ring of Destruction
• Turn 1 (going first): Open a searcher or draw (Thunder Dragon, Sangan, Upstart Goblin) and look for a 1-card starter; no combo steps are recorded, so the line is text-inferred only
• Turn 2 (going second): Use Mirror Force, Torrential Tribute or Breaker to reset the opponent's board, then rebuild with Fusion Monsters from the Extra Deck
• Recovery: Spirit Reaper, Night Assailant and Phoenix Wing Wind Blast recur or reset the board, and Sinister Serpent and Sangan recover the Deck
• After siding: Not evaluable: the deck has no Side Deck, so no post-side plan exists

Why it scores here

The deck is scored as a Toolbox system, not as an average of its cards. Its real engine is weak: the exact Gravekeeper's name covers only 2 of 55 Main Deck copies (2.9% purity), and the 3 Forbidden cards (Delinquent Duo, Pot of Greed, Graceful Charity) make the list illegal under OCG rules. Consistency is low, with 22 singletons, a 17.5% chance of at least one Gravekeeper's Spy in a 5-card opening hand, and no recorded combos to show a reliable line. Interaction is broad (Mirror Force, Torrential Tribute, Heavy Storm, Ring of Destruction, Mystical Space Typhoon) and Fusion access gives it reasonable closing power, but neither offsets the opening-hand inconsistency. The score is capped low because the list is Illegal; the popularity of the archetype did not earn points.

Dimension scores

How the score was computed

Strategy profile: Primary Toolbox with Control as a minor secondary; the Toolbox profile is used directly. Structural ≈ 39.2, Going First ≈ 40, Going Second ≈ 32, Meta = provisional, Tournament Reliability ≈ 35. Modifiers: banlist_exposure (-6); no_side_deck (-4). Final formula: No reliable metagame: 0.80*Structural + 0.20*TournamentReliability = 0.80*39.2 + 0.20*35 = 38.4; contextual modifiers -10 give 28.4; Illegal cap applied, so the final score is 20 (theoretical/structural-only)

Probability & combo summary

• Opening a starter: P(≥1) ≈ 0.18 · 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

• Layered removal and board-reset cards (Mirror Force, Torrential Tribute, Heavy Storm, Ring of Destruction, MST)
• Strong Fusion closers in the Extra Deck (King Dragun, Master of Oz, Gatling Dragon)
• Searchers and recursion (Thunder Dragon, Sangan, Sinister Serpent, Spirit Reaper) add some resource recovery

Weaknesses

• Illegal: three Forbidden cards are in the Main Deck
• Exact archetype purity is 2.9%, so there is no coherent Gravekeeper's engine
• No recorded combos, so no verified line or floor exists
• No Side Deck

Critical choke points

• Fusion access depends on Metamorphosis, the only Fusion enabler in the Main Deck
• Searcher density (7 cards, P(>=1) about 0.51) is the only route to a live hand

Recommended changes

Evidence & confidence

• Verified: Main 55, Extra 15, Side 0 counts are within the OCG size rules; Delinquent Duo, Pot of Greed and Graceful Charity are Forbidden in OCG and run at 1 copy each; Card texts and stats for all listed cards are from the resolved card table; Exact archetype purity is 2.9% (2 of 68 archetype copies)
• Inferred: Starter probability P(>=1 Gravekeeper's Spy in 5 cards) = 0.175; Brick risk and redundancy estimates from copy histogram and card roles; Structural dimension scores and weight profile choice
• Provisional: Meta Power is null because no dated metagame sample exists; Matchup fit (d13) is provisional because no tournament_context is supplied
• Data gaps: No combos supplied, so combo floor, median and ceiling are text-only inference No tournament link, so archetype meta-share and per-pilot records are absent No win-rate telemetry exists in YGOVN No Side Deck, so post-side performance cannot be assessed Meta Power is provisional without a dated metagame sample
