K9 Deck #773010 — Yu-Gi-Oh! OCG

Deck — Deck Power Evaluation

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

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

Legality

Main 40 / Extra 15 / Side 0 — status under the rules at evaluation time: Illegal. 3 violation(s).

Identity & game plan

• Win condition: Xyz pressure from the Train and K9 Level 10 and Level 5 Xyz monsters, led by Superdreadnought Rail Cannon Gustav Rocket (5000 ATK) and Gustav Max's direct damage; K9 Xyz monsters (K9-66X Jacks removal, Light Dragon @Ignister) to clear blockers, with Gustav Max's 2000 direct damage as reach
• Turn 1 (going first): Normal Summon K9-04 Noroi or K9-17 Izuna (both listed as Normal-Summonable without Tribute), special-summon a K9 monster from the Deck, and search with A Case for K9 or Exceptional Schedule toward a Level 10 Train engine
• Turn 2 (going second): Hold Ash Blossom, Droll & Lock Bird, Maxx C and Red Reboot as hand traps; respond to the opponent's first summon or search, then rebuild through K9-66a Jokul and Night Train Blue Traveler
• Recovery: Ancient Gear Box and Night Train Blue Traveler return searchers from the Graveyard; Forced Release re-enters a K9 Xyz from the Extra Deck
• After siding: Not evaluable: the deck runs 0 side cards, so there is no post-side plan

Why it scores here

This deck is Illegal in OCG: it runs 3 copies of K9-04 Noroi, 1 Triple Tactics Talent and 1 Varudras, all Forbidden, so the score is capped and the evaluation is structural-only. Structurally it reliably opens a K9 or Train starter: the 12 exact-name K9 core copies give about 0.85 probability of at least one in a 5-card opening hand (Inferred). Its strength is layered interaction and resilience, with 5 hand traps (Ash Blossom, Droll and Lock Bird, Maxx C, Red Reboot), 10 negation-text cards and 14 searcher-text cards. Its endboard reach comes from Level 10 Xyz monsters, especially Gustav Rocket (5000 ATK) and Gustav Max's direct damage. The score comes from consistency, interaction and closing power evaluated on the system, not from averaging the card scores. The K9 and Train engines are split (exact-name purity 21.8%, 43 off-archetype copies), and there is no side deck, so the list has no adaptation plan. Popularity is not credited: K9 usage stats only confirm the archetype is real.

Dimension scores

How the score was computed

Strategy profile: Midrange primary, Toolbox secondary (no separate blend ratio computed). Structural ≈ 55, Going First ≈ 55, Going Second ≈ 52, Meta = provisional, Tournament Reliability ≈ 45. Modifiers: Banlist exposure (-6); No side deck (-2); Engine split (-2). Final formula: No reliable metagame: 0.80*Structural + 0.20*TournamentReliability = 0.80*55 + 0.20*45 = 53; modifiers -10 gives 43; capped at 35 because the deck is Illegal (theoretical/structural-only)

Probability & combo summary

• Opening a starter: P(≥1) ≈ 0.85 · 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

• Layered hand-trap and negation coverage (5 hand traps, 10 negation-text cards)
• Multiple lines: K9 Xyz, Train Level 10 chain and Ancient Gear Box recursion
• High endboard reach from Gustav Rocket and Gustav Max direct damage

Weaknesses

• Illegal in OCG: three Forbidden cards must be removed before it can be played
• No side deck, so no post-side adaptation
• Split engine (Train and K9) lowers consistency

Critical choke points

• K9 Xyz summons depend on a K9 Level 5 monster, and Noroi (Forbidden) is one of the Normal-Summon starters
• Train Level 10 Xyz access depends on Night Train and Heavy Armored Knight Babeldecker, with no independent backup

Recommended changes

Evidence & confidence

• Verified: Illegal status: 3 Forbidden copies in the OCG list; Main 40 and Extra 15 meet size rules; Gustav Rocket 5000 ATK and Gustav Max direct damage text
• Observed: Extra Deck fully used (12 Xyz, 3 Link); Exact-name archetype purity 21.8%
• Inferred: Starter probability about 0.85; Hand-trap hit rate about 0.58 on a 6-card hand; Interaction and resilience estimates from card text
• Provisional: Meta Power (no dated metagame sample); Matchup and format fit (no tournament data)
• 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 K9 in OCG Meta Power is Provisional without a dated metagame sample Side deck is empty, so post-side performance is unmeasurable
