K9 Deck #772313 — Yu-Gi-Oh! OCG

Deck — Deck Power Evaluation

Final Contextual Deck Power: 25/100 (±8 · Confidence: Low)

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

Legality

Main 53 / Extra 17 / Side 0 — status under the rules at evaluation time: Illegal. 3 violation(s).

Identity & game plan

• Win condition: Xyz and Link pressure from K9 and Vanquish Soul board presence, closing through Extra Deck boss monsters such as K9-66X Jacks, Number C104 and Arc Rebellion Xyz Dragon; Synchro and Number follow-up (Swordsoul Supreme Sovereign, Super Starslayer TY-PHON) once the first board is established
• Turn 1 (going first): Open on a Vanquish Soul searcher or K9 Normal Summon (K9-66b Lantern, K9-17 Izuna, K9-66a Jokul), reach a Level 5 pair for an Xyz, and keep Ash Blossom or Ghost Belle up for interruption
• Turn 2 (going second): Hold hand traps (Ash Blossom, Ghost Belle, Droll and Lock Bird, Maxx C, Red Reboot) to stop the opponent's first summon, then convert with K9 Xyz follow-ups
• Recovery: Re-search through K9 and Vanquish Soul searchers (Vanquish Soul Razen, Vanquish Soul Start, A Case for K9) and rebuild a Level 5 Xyz pair from hand
• After siding: Not evaluable: the deck runs no side deck (0 cards), so there is no post-side plan

Why it scores here

The deck's K9 core (12 K9 copies plus Vanquish Soul and Umbral Horror support) and 16 searcher-text cards give a high chance of finding a starter, with roughly 0.85 odds of at least one searcher in the opening five cards (Inferred, hypergeometric). Its seven hand traps and two Ash Blossom copies give it real interruption tools on both turns, which is what keeps the structural score above a plain bricky midrange. The score is held down by the illegal list: 17 Extra Deck cards exceed the OCG cap of 15, A Case for K9 runs two copies against a limit of one, and Baronne de Fleur is Forbidden. The deck has no recorded combos, no tournament link and no side deck, so the combo, matchup and side-deck dimensions rest on text reads and gaps. The score reflects the system's consistency and interaction, not the popularity of the K9 archetype and not an average of individual card scores.

Dimension scores

How the score was computed

Strategy profile: Midrange. Structural ≈ 52, Going First ≈ 55, Going Second ≈ 50, Meta = provisional, Tournament Reliability ≈ 45. Modifiers: Banlist exposure (-6); Oversize Extra Deck (-6). Final formula: Illegal cap: 0.80*Structural(52) + 0.20*TournamentReliability(45) + modifiers(-12) = 38.6, capped at 25 (theoretical/structural-only; not a normal Final score)

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

• Dense searcher text (16 cards) gives strong starter access
• Seven hand traps provide interruption on both turns
• Multiple Xyz and Link boss options with 2600 to 3300 ATK bodies

Weaknesses

• Illegal as built: Extra Deck over cap, A Case for K9 over copy limit, Forbidden Baronne de Fleur
• Off-archetype dilution: exact K9 purity 17.1%
• No side deck

Critical choke points

• Extra Deck count and Forbidden card must be fixed before any normal evaluation
• Single-copy K9 Xyz finishers (K9-66X Jacks, K9-X Ripper) are unrecoverable if removed from the board

Recommended changes

Evidence & confidence

• Verified: Main 53 and Extra 17 counts from legality block; Baronne de Fleur is Forbidden; A Case for K9 is Limited with 2 copies run; Card stats and text from the cards array; Usage stats: K9-66a Jokul and K9-00 Lupis core inclusion
• Inferred: Starter access ~0.85 and archetype-core open ~0.77 from hypergeometric estimates; Brick and interruption estimates from hand-trap and searcher counts; Going-first and going-second scores from text and structure
• Provisional: Matchup and format fit (D13), with no tournament or meta sample
• 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, going-second, matchup, brick or starter rates) Meta Power is provisional without a dated metagame sample Data inconsistency: K9-X Werewolf appears in the cards array as an Extra Deck copy but usage_statistics marks it in_this_deck=false; cards array was treated as source of truth Title is null, so the deck is identified only by id and archetype
