Ninja Deck #680223 — Yu-Gi-Oh! OCG

Deck — Deck Power Evaluation

Final Contextual Deck Power: 20/100 (±10 · Confidence: Low)

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

Legality

Main 40 / Extra 15 / Side 0 — status: Illegal. 1 violation(s).

Identity & game plan

• Win condition: Fusion and Synchro bosses (Meizen the Battle Ninja, Yaguramaru, Draco Berserker of the Tenyi, Juraishin) supported by Ninja recursion and Ninjitsu Art disruption; Ninja monsters attacking directly via Meizen and board-breaking from Ninjitsu Art Tool - Iron Digger
• Turn 1 (going first): Normal Summon Ninja Grandmaster Hanzo to search a Ninjitsu Art card, or open Tobari/Mitsu/Green Ninja for a Ninja-chain board into a Fusion or Synchro boss
• Turn 2 (going second): Respond to the opponent's board with Mitsu's negation, Ninjitsu Art of Dancing Leaves, Swords of Concealing Light or Evenly Matched, then rebuild through Hanzo and Notebook searches
• Recovery: Recycle Ninja monsters and Ninjitsu Art cards from the GY via Ninjitsu Art Notebook of Mystery and Hidden Village of Ninjitsu Arts; the GY-recovery text is present but not validated against real boards
• After siding: Not assessable: the deck runs no Side Deck (0 of up to 15 slots)

Why it scores here

The 40-card Main Deck opens into the Ninja engine reliably: the archetype-core group has a 0.987 chance of at least one Ninja-core card in an opening hand of five, and Ninja Grandmaster Hanzo, Tobari, Mitsu, Green Ninja and Baku give several independent starters, which is why D1, D5 and D14 score in the low 60s. The score is held back by the lack of any recorded boards, so the combo ceiling (D3) and floor (D4) are text-only inferences, and by 23 Level-0 spell and trap slots and 28 off-archetype copies that raise brick risk and dilute coherence. The deck has no Side Deck, which caps D12 at 20. Pot of Greed is Forbidden in OCG and is run three times, so the list is Illegal; under the rubric it does not receive a normal Final Contextual score and is capped at 20 as a theoretical, structural-only read. Popularity of the Ninja archetype was not counted toward power, and card scores were not averaged into the deck score.

Dimension scores

How the score was computed

Strategy profile: Midrange primary; Toolbox used only as a tie-break for reading D7 and D10. Structural ≈ 49, Going First ≈ 48, Going Second ≈ 45, Meta = provisional, Tournament Reliability ≈ 40. Modifiers: banlist exposure (-12); illegal-list cap (0). Final formula: Structural 48.75 → 0.80*48.75 + 0.20*40 = 47 → modifiers −12 = 35 → Illegal cap applied, final 20 (theoretical/structural-only; Meta provisional)

Probability & combo summary

• Opening a starter: P(≥1) ≈ 0.99 · 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

• Ninja-core coverage in opening hands is very high (≈0.987 for at least one core card in five)
• Multiple independent Ninja starters (Hanzo, Tobari, Mitsu, Green Ninja, Baku)
• Fully populated Extra Deck (15/15) with Fusion and Synchro bosses
• Layered interaction: Mitsu negation, Dancing Leaves, Swords, Evenly Matched, Daruma

Weaknesses

• Illegal list: Pot of Greed (Forbidden in OCG) run three times
• No Side Deck, so no post-side adaptation
• 23 Level-0 spell/trap slots and 28 off-archetype copies lower coherence and raise brick risk
• No recorded boards, so combo ceiling and floor are unverified

Critical choke points

• Hanzo as the main searcher; a dead or removed Hanzo narrows the Ninjitsu Art route
• Single Forbidden card in the list makes the whole deck illegal until corrected

Recommended changes

Evidence & confidence

• Verified: Deck is Illegal: Pot of Greed is Forbidden and run 3 copies; Main 40, Extra 15, Side 0 against OCG size rules 40–60 / 0–15 / 0–15; Ninja archetype exact-name purity 49.1% (27 of 55 Main+Extra copies); Archetype-core group ≥1 in opening 5 = 0.987 from the resolved list; Fusion 7 and Synchro 8 in Extra Deck; no tournament link or win-rate data
• Observed: Ninja archetype core inclusion in usage stats: Hanzo, Tobari, Mitsu, Green Ninja, Dancing Leaves at 100%
• Inferred: Midrange primary strategy from Ninjitsu Art and Hanzo search structure; Multiple independent starters support D5 and D14 scores; Brick and coherence estimates from Level-0 count and off-archetype copies; Interaction density read from Mitsu, Dancing Leaves, Swords, Evenly Matched, Daruma text
• Provisional: Meta Power null: no dated metagame sample; D13 matchup and format fit as a neutral placeholder; Tournament reliability 40 without tournament or per-pilot data
• Data gaps: No combos supplied: combo floor, median and ceiling are text-only inference No tournament link: archetype meta-share and per-pilot record absent No win-rate telemetry (going-first/second, matchup, brick/starter rates) Meta Power is provisional without a dated metagame sample Deck title is null No Side Deck entries (0 of up to 15), so no post-side read is possible
