Ninja Deck #768034 — Yu-Gi-Oh! OCG

Deck — Deck Power Evaluation

Final Contextual Deck Power: 59/100 (±8 · Confidence: Medium)

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

Legality

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

Identity & game plan

• Win condition: Ninja monsters attack directly or pressure through Meizen the Battle Ninja (2500 ATK, direct attacks) and Yaguramaru, backed by Ninja Grandmaster Saizo and Blade Armor Ninja on the Link and Xyz side.; Link and Fusion boards (Underworld Goddess, Ultimate Great Insect) that negate or overwhelm the opponent's field.
• Turn 1 (going first): Normal Summon Hanzo or Tobari, search or Special Summon a second Ninja, use Ninjitsu Art Notebook or Dancing Leaves for board presence, then Fusion or Link into Meizen or Saizo.
• Turn 2 (going second): Hold Ghost Ogre & Snow Rabbit or Effect Veiler to stop the opponent's first engine or boss, then rebuild through Ninja searchers and Mitsu-based Defense Position plays.
• Recovery: Recover through Baku the Beast Ninja (returns a Ninja or Ninjitsu Art card), Ninjitsu Art Tool - Iron Digger and Book of Moon or Eclipse to reset the opponent's board, then rebuild from the GY and Extra Deck.
• After siding: No side deck is registered, so no post-side plan can be evaluated; the deck relies entirely on game-one construction.

Why it scores here

The deck opens reliably on its Ninja engine: the nine copies of Tobari, Kagero and Mitsu plus three Hanzo searchers give about a 74% chance of at least one low-level starter in a 5-card opening hand (Inferred), and 40/40 Main with 15/15 Extra and 10 three-ofs keeps the list compact. Its interaction is layered across hand traps (Ghost Ogre, Effect Veiler), Mitsu's negation text, Book of Moon and Eclipse, and Iron Digger and Tenchi Kaimei removal, which supports the going-second and end-board scores. Offensive power comes from Meizen and Yaguramaru Fusion pressure and Link/Xyz finishers, not from popularity: archetype usage stats confirm the list is real but do not raise the score. The score comes from consistency, interaction and closing power measured on the system, not from averaging card scores. No combo boards, tournament data or side deck exist, so median output, matchup fit and post-side adaptability are capped and the band is wide.

Dimension scores

How the score was computed

Strategy profile: Midrange. Structural ≈ 61.5, Going First ≈ 61, Going Second ≈ 62, Meta = provisional, Tournament Reliability ≈ 60. Modifiers: No side deck (-2). Final formula: 0.80*Structural + 0.20*TournamentReliability (Meta provisional) + ContextModifiers(-2) = 59.2, rounded to 59

Probability & combo summary

• Opening a starter: P(≥1) ≈ 0.74 · 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

• Compact 40/15/0 build with 10 three-of Main cards and an unbroken Ninja engine core
• Layered hand-trap and negation interaction covering both going-first and going-second turns
• Strong Fusion and Link finishers with direct-attack and double-attack text

Weaknesses

• No side deck, so no post-side adaptation in a best-of-three
• Exact Ninja name purity is under 50% and the generic Book and Knightmare copies dilute the engine
• No recorded combos, so median output and ceiling are text-only estimates

Critical choke points

• Low-level starters (Tobari, Kagero, Mitsu, Green Ninja) are the sole opening engine; a hand without one relies on Hanzo searches
• Meizen and Yaguramaru require 2 Ninja monsters of different types, so Extra access depends on the Main Deck's Ninja spread

Recommended changes

Evidence & confidence

• Verified: Legal status with Limited Instant Fusion and Reinforcement of the Army at one copy each; 40/15/0 composition and copy histogram 6/2/10; Card text for Hanzo, Tobari, Meizen, Yaguramaru, Underworld Goddess and the hand traps
• Observed: Usage stats show the Ninja core is present in the deck (proxy only)
• Inferred: 74% chance of at least one low-level starter in hand 5; 0.65 hand-trap chance going second; Interaction density and resilience from text and flags
• Provisional: Meta Power is null: no dated metagame sample; Matchup fit and median output are provisional
• Data gaps: No combos supplied: combo floor, median and ceiling are text-only inference No side deck registered: post-side adaptability cannot be measured No tournament link: archetype meta-share and match record absent usage_statistics.missing_core lists Saizo, Meizen, Ultimate Great Insect, I:P Masquerena, Blade Armor Ninja and Yaguramaru as missing, yet all six are in the deck's Extra Deck list; the core-presence check appears to scan only the Main Deck, so core coverage is unreliable No win-rate telemetry exists in YGOVN for going-first/second, matchup or brick rate
