Ninja Deck #769212 — Yu-Gi-Oh! OCG

Deck — Deck Power Evaluation

Final Contextual Deck Power: 36/100 (±8 · Confidence: Low)

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

Legality

Main 55 / Extra 14 / Side 0 — status: Illegal. 1 violation(s).

Identity & game plan

• Win condition: Ninja monster beatdown and Ninjitsu Art value, backed by Fusion, Link and Xyz boss monsters (Meizen, Yaguramaru, Saizo, Borrelsword, TY-PHON); Disruption from hand traps and negations that lets Ninja bodies attack through an interrupted opponent
• Turn 1 (going first): Open a Ninja starter (Tobari, Mitsu, Hanzo or Green Ninja) and use Ninjitsu Art Notebook or Hanzo to find more Ninja bodies, then Fusion or Link into a boss. Hand traps are held for the opponent's first activation.
• Turn 2 (going second): Hold hand traps (16 copies, about 89% to hold at least one in a six-card hand) to stop the opponent's board, then rebuild with Ninja bodies and Ninjitsu Art Tool or Duplication.
• Recovery: Ninja monsters recur from the GY (Tobari, Baku, Kagero, Iron Digger) and Hanzo and Notebook re-search Ninja bodies and Ninjitsu Art.
• After siding: Not evaluable: the deck has no Side Deck, so there is no post-side plan.

Why it scores here

The deck reliably opens a Ninja starter: the 22 exact-name Ninja cards give about 93% chance of at least one in a five-card opening hand (Inferred), and a Ninja body or Ninjitsu Art search is usually reachable by turn two. Its hand-trap density (16 copies, about 89% to hold one in a six-card hand) gives it real going-second disruption. Conversion into pressure relies on Fusion, Link and Xyz bosses, but only 32% of the Main Deck is exact-name Ninja and 47 slots are off-archetype (Mulcharmy, Eyes Restrict, Invoked, Spright, Book of), so the engine is diluted and the bricking risk is high. No recorded boards exist, so floor, median and ceiling are text-only inference and are not averaged. The score is capped at 36 because the list is Illegal: Ash Blossom & Joyous Spring is run three times against an OCG limit of two. Popularity did not earn points, and card scores were not averaged.

Dimension scores

How the score was computed

Strategy profile: Midrange. Structural ≈ 50.3, Going First ≈ 46, Going Second ≈ 56, Meta = provisional, Tournament Reliability ≈ 40. Modifiers: Legality: over copy limit (Illegal) (-12). Final formula: 0.80*Structural + 0.20*TournamentReliability (Meta provisional); Final = 48.2 before the legality modifier, then -12 for Illegal status = 36

Probability & combo summary

• Opening a starter: P(≥1) ≈ 0.93 · 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

• Large Ninja core: 22 exact-name cards, about 93% to open at least one in a five-card hand (Inferred)
• Heavy hand-trap and negation density (16 hand traps, 9 negation texts) for going second (Inferred)
• Strong boss options across Fusion, Link and Xyz (TY-PHON, Borrelsword, Meizen, Yaguramaru)

Weaknesses

• Illegal list: Ash Blossom run 3 times against an OCG limit of 2 (Verified)
• No Side Deck, so no post-side adaptability (Verified)
• Low archetype purity (31.9%) with 47 off-archetype slots dilutes the engine (Verified count)
• Many dead draws possible from 8 Mulcharmy cards and Level 0 spells/traps (Inferred)

Critical choke points

• Ninja starter presence in the opening hand (about 93% for the core group, but no single card above 25% per copy) (Inferred)
• Ninjitsu Art value chain depends on Hanzo, Notebook and Iron Digger; loss of these removes the engine (Inferred)

Recommended changes

Evidence & confidence

• Verified: Main 55 and Extra 14 are within OCG size rules (40-60 and 0-15); Ash Blossom & Joyous Spring: 3 copies vs OCG limit of 2 (Semi-Limited); 0 Side Deck cards; Archetype purity 31.9%, 47 off-archetype copies; Copy histogram: 8 at 1 copy, 4 at 2, 13 at 3
• Inferred: Opening and hand-trap hit rates from hypergeometric estimates; Engine conflict and brick estimate from off-archetype count; Starter-diversity and recursion reads from card text; Strategy classification as Midrange with Stun and Toolbox secondaries
• Provisional: Meta Power (null, no dated metagame sample); Matchup and format fit (no tournament link or meta-share)
• 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 are 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 has no title (deck_name null) No Side Deck
