Ninja Deck #755209 — Yu-Gi-Oh! OCG

Deck — Deck Power Evaluation

Final Contextual Deck Power: 35/100 (±8 · Confidence: Low)

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

Legality

Main 54 / Extra 16 / Side 0 — status under the rules at evaluation time: Illegal. 2 violation(s).

Identity & game plan

• Win condition: Ninja board of Ninjitsu Art-driven monsters converting into Fusion, Link and Xyz boss monsters (Meizen, Yaguramaru, Super Starslayer TY-PHON, Supreme King Z-ARC), with direct attacks from Meizen; Stardust Dragon and Underworld Goddess as board-control closers after interaction
• Turn 1 (going first): Open a Ninja starter (Tobari, Mitsu, Hanzo, Green Ninja or Baku), search or Special Summon into a Ninjitsu Art Trap or Iron Digger, then link or fuse into a boss monster
• Turn 2 (going second): Use hand traps (Ash Blossom, Ghost Ogre, Maxx C) and Dark Hole or Heavy Storm to strip the opponent's board, then rebuild with Ninja recursion from the GY
• Recovery: Recycle Ninja monsters from the GY through Iron Digger, Hidden Village and Ninjitsu Art cards, and use Tobari's GY effect to resummon
• After siding: Not evaluable: the deck runs no side deck (side_count 0), so there is no post-side plan

Why it scores here

This is a theoretical, structural-only read because the list is Illegal: it runs Cross-Sheep (Forbidden in OCG) and has 16 Extra Deck cards against a 15-card maximum, so it does not receive a normal Final Contextual score. Its engine is reasonably accessible: the Ninja core (22 copies) has about a 94% chance of at least one card in a 5-card opening hand (Inferred, hypergeometric), and the Ninjitsu Art cards give it recursion and removal. Interaction is the strongest area, with 5 hand traps, Solemn Judgment, Dark Hole, Heavy Storm and Destructive Daruma supporting it. The main weaknesses are a low Ninja purity of about 33%, which leaves 47 off-archetype copies that raise brick risk, the absence of any side deck, and the absence of recorded combos or tournament data, so the floor and median are unknown. Structural power is a blend of the 14 dimensions weighted for a Midrange profile, not an average of card scores, and popularity did not earn points.

Dimension scores

How the score was computed

Strategy profile: Midrange. Structural ≈ 53, Going First ≈ 55, Going Second ≈ 60, Meta = provisional, Tournament Reliability ≈ 40. Modifiers: banlist exposure (-8); no side deck (-2). Final formula: Illegal cap: 0.80*Structural(53) + 0.20*TournamentReliability(40) = 50.4, minus 10 in modifiers = 40.4, capped to 35 for an Illegal list; theoretical/structural-only (Meta provisional)

Probability & combo summary

• Opening a starter: P(≥1) ≈ 0.94 · 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

• Core Ninja engine is accessible in the opening hand at about 94%
• Layered interaction: five hand traps, Solemn Judgment, Dark Hole, Heavy Storm and Destructive Daruma
• Strong Extra Deck closers, including Supreme King Z-ARC (4000 ATK) and Super Starslayer TY-PHON

Weaknesses

• Illegal list: Forbidden Cross-Sheep and a 16-card Extra Deck
• Low Ninja purity (about 33%) with 47 off-archetype copies
• No side deck, so there is no post-side plan
• No combo samples or tournament data, so floor and median are unknown

Critical choke points

• The Ninja starter layer (Tobari, Mitsu, Hanzo and Green Ninja) is narrow, so a single starter loss can stall the engine
• Forbidden Cross-Sheep occupies an Extra Deck slot that must be removed before the list is legal

Recommended changes

Evidence & confidence

• Verified: Legality: Illegal, Cross-Sheep Forbidden with 1 copy run, Extra Deck 16 over the 15 maximum; Main Deck size 54 is within 40–60; side count is 0; Card text and stats for the Ninja engine, hand traps and Extra Deck bosses from the evidence excerpts
• Inferred: P(at least one Ninja core card in hand of 5) ≈ 0.94; Interaction density and board-breaking strength from card text; Brick risk from off-archetype composition
• Provisional: Meta Power and format fit (no dated metagame sample); Median and floor output (no combo samples)
• 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 for going-first/second, matchup, or brick/starter rates Meta Power is Provisional unless a dated metagame sample is supplied No side deck: post-side adaptability cannot be measured
