Call of the Haunted Deck #773769 — Yu-Gi-Oh! Master Duel

Deck — Deck Power Evaluation

Final Contextual Deck Power: 54/100 (±6 · Confidence: Medium)

• Primary strategy: Midrange
• Secondary strategies: Toolbox, Combo
• Format: master-duel

Legality

Main 40 / Extra 15 / Side 0 — status: Legal.

Identity & game plan

• Win condition: Fusion Summon Gem-Knight Ruby, Topaz or Amethyst from the Extra Deck, using Gem-Knight Garnet/Tourmaline and Gem-Knight monsters, to push damage through a board.; Call of the Haunted revives a Gem-Knight from the GY, and Gem-Knight Fusion recovers from the GY by banishing a Gem-Knight monster.
• Turn 1 (going first): Normal Summon Gem-Armadillo or Gem-Turtle to search the Gem-Knight engine (Fusion or Fusion-related Gem-Knight), then extend through Alexandrite or Dai into a Fusion Summon.
• Turn 2 (going second): Use Mystical Space Typhoon, Swords of Revealing Light, Compulsory Evacuation Device or Overexaggeration to clear the opposing set-up, then convert with Fusion monsters or a Xyz from the Extra Deck.
• Recovery: Gem-Knight Fusion from the GY, Call of the Haunted from the GY on a Gem-Knight, and Alexandrite recursion keep the deck playing after one interruption.
• After siding: No side Deck is registered (0 cards), so there is no post-side plan in the list; any change requires a rebuild outside the registered deck.

Why it scores here

The deck is scored as a connected Gem-Knight system, not as an average of its card scores. Gem-Armadillo, Gem-Turtle, Alexandrite, Garnet and Unexpected Dai give several independent starter routes, and the 17-copy core group opens at least one copy in about 95% of going-first hands (Inferred). Fusion Monsters (Ruby, Topaz, Amethyst) and Xyz/Link finishers give real closing power, but no recorded boards exist, so the ceiling and median are text-based only. Interaction (MST, Swords, Compulsory Evacuation Device, Overexaggeration, Jelly Cannon) is dense but has no hand traps or negations, and the deck runs no side deck, which holds back the score. Popularity or archetype label did not add points; 10 of 15 Extra Deck slots are off-engine Xyz/Link cards, which dilutes the system.

Dimension scores

How the score was computed

Strategy profile: Midrange. Structural ≈ 60, Going First ≈ 61, Going Second ≈ 57, Meta = provisional, Tournament Reliability ≈ 52. Modifiers: Weak post-side plan (-2); Extra Deck engine dilution (-2). Final formula: 0.80*Structural + 0.20*TournamentReliability + ContextModifiers (Meta provisional); 0.80*60 + 0.20*52 = 58.4, minus 4 = 54.4, rounded to 54

Probability & combo summary

• Opening a starter: P(≥1) ≈ 0.95 · key two-card combo ≈ — · full-brick estimate ≈ 0.05 (all Inferred)
• Combo output: best PowerIndex —, median —, board-per-starter —
• Turn order: 0 going-first lines vs 0 going-second lines

Strengths

• Multiple independent starter routes (Gem-Armadillo, Gem-Turtle, Alexandrite, Garnet, Unexpected Dai)
• Dense removal-text interaction across Spell/Trap slots (16 cards)
• Strong closing Fusion and Xyz/Link threats (Ruby 2500, Topaz double attack, Ningirsu 2500)
• Clean main deck: 17 distinct cards, all Unlimited banlist status
• Recovery through Gem-Knight Fusion and Call of the Haunted from the GY

Weaknesses

• No hand traps or negations (hand_trap_group count 0)
• No side deck, so no post-side adaptation
• 10 of 15 Extra Deck slots are off-engine Xyz/Link monsters
• 22 Spell/Trap cards without a monster role raise brick risk
• No recorded boards, so combo ceiling and median are unverified

Critical choke points

• Gem-Knight Fusion and Fusion monsters need Garnet/Tourmaline on the field or in hand, so losing those to interaction stalls the Fusion route
• Call of the Haunted depends on a Gem-Knight Monster in the GY
