Book of Deck #762005 — Yu-Gi-Oh! Master Duel

Deck — Deck Power Evaluation

Final Contextual Deck Power: 30/100 (±10 · Confidence: Low)

• Primary strategy: Stun
• Secondary strategies: Toolbox
• Format: master-duel

Legality

Main 40 / Extra 15 / Side 0 — status under the rules at evaluation time: Illegal. 4 violation(s).

Identity & game plan

• Win condition: Ninja Extra Deck beaters (Meizen the Battle Ninja, Yaguramaru, Blade Armor Ninja, Jioh) attacking through a board protected by hand traps.; Divine Arsenal AA-ZEUS - Sky Thunder as a single high-ATK Xyz finisher; needs Level 12 material and is not a reliable core line.
• Turn 1 (going first): Open with Ninja Grandmaster Hanzo or a Ninja searcher, hold hand traps (Ash Blossom, Maxx C, D.D. Crow, Infinite Impermanence) for the opponent's first action, and convert into a Ninja Fusion or Link board.
• Turn 2 (going second): Use the 12 hand traps to answer the opponent's starter in hand, then rebuild the Ninja board with Tobari, Mitsu or Hanzo and attack through with Extra Deck monsters.
• Recovery: Search Ninja or Ninjitsu Art cards with Hanzo, Iron Digger or Reinforcement of the Army, and use Ninjitsu Art of Duplication or Notebook of Mystery to re-deploy Ninja monsters.
• After siding: None. The Side Deck is empty (0 of up to 15 cards), so there is no post-side plan and the deck cannot adapt between games in a best-of-3.

Why it scores here

The deck's functional engine is a Ninja package: three copies each of Hanzo, Tobari and Mitsu give it several small starters, and three Ninjitsu Art cards plus Iron Digger and Duplication give it a recovery route. Its interaction is the strongest part of the evaluation: 12 hand traps and about 11 negation effects make the board hard to establish against, which earns the Stun-leaning structural score. The score does not come from averaging card scores, and it does not come from Ninja being a familiar archetype. Dead-in-hand risk is high on the going-first side, because most hand traps need the opponent to act, and the empty Side Deck removes any post-side plan. Four Forbidden cards and an over-limit Maxx "C" make the list illegal, so the score is capped at 30 and is only a theoretical read of the structure.

Dimension scores

How the score was computed

Strategy profile: Stun (D13 dropped and renormalised over 86 because Meta is provisional). Structural ≈ 52, Going First ≈ 50, Going Second ≈ 58, Meta = provisional, Tournament Reliability ≈ 45. Modifiers: banlist exposure (-12). Final formula: Theoretical: 0.80*Structural(52.4) + 0.20*TournamentReliability(45) + modifiers(-12) = 38.9, capped at 30 because the list is Illegal; Meta provisional

Probability & combo summary

• Opening a starter: P(≥1) ≈ — · 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

• 12 hand traps and about 11 negation effects give high interaction density.
• Ninja family coherence: 23 Ninja cards plus 7 Ninjitsu Art cards.
• Going-second hand-trap coverage of about 90% in a 6-card hand.
• Multiple Ninja Extra Deck threats (Meizen, Yaguramaru, Blade Armor, Jioh).

Weaknesses

• Illegal list: four Forbidden cards and an over-limit Maxx "C".
• Empty Side Deck, so no post-side plan.
• Going-first bricks: most hand traps need the opponent to act first.
• No combo data, so ceiling and median cannot be measured.

Critical choke points

• The Ninja summon-enabling starters (Hanzo, Tobari, Mitsu) are the only route to the Extra Deck monsters.
• A non-Ninja opening with no searcher and no hand trap leaves the deck with no going-first line.

Recommended changes

Evidence & confidence

• Verified: Main 40, Extra 15, Side 0; the Main and Extra sizes are legal.; Four Forbidden or over-limit violations (Maxx "C" x3, Called by the Grave x2, Pot of Prosperity x1, Bagooska x1).; Card text and copy histogram from the evidence pack.
• Inferred: Consistency and brick estimates from the hypergeometric values.; Stun-leaning structure from hand-trap and negation text density.; Going-first and going-second splits from hand-trap coverage.
• Provisional: Meta Power (null) and matchup fit (D13).
• Data gaps: No combos supplied: combo floor, median and ceiling are text-only. No tournament link: archetype meta-share and pilot match record are absent. No win-rate telemetry, so brick, going-first and matchup rates are Inferred. Meta Power is Provisional without a dated metagame sample. Side Deck is empty, so post-side scoring is unmeasurable.
