K9 Deck #773203 — Yu-Gi-Oh! OCG

Deck — Deck Power Evaluation

Final Contextual Deck Power: 20/100 (±5 · Confidence: Medium)

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

Legality

Main 55 / Extra 15 / Side 0 — status under the rules at evaluation time: Illegal. 3 violation(s).

Identity & game plan

• Win condition: Xyz pressure from the Extra Deck (Number 104: Masquerade V, Number C104, Number 39 monsters) backed by hand-trap protection of the field; Umbral Horror / Barian's searcher chains into Xyz summons; K9 Izuna and K9-ØØ Lupis as Main Deck beaters
• Turn 1 (going first): Open a searcher (Seventh Tachyon, V Umbral Horror, Gorgonic Umbral Horror, Barian's Seventh Untopia) and build toward a 2-monster Xyz; hold Ash Blossom or Infinite Impermanence for the opponent's first engine
• Turn 2 (going second): Use the six-card hand to present a hand trap (Ash Blossom, Droll & Lock Bird, Ghost Belle, Ghost Ogre) against the opponent's starter, then search and Xyz through the opening
• Recovery: Recover through Mulcharmy Fuwalos/Purulia draw triggers and Umbral Horror searchers from the GY and Deck, then re-summon Xyz from the Extra Deck
• After siding: No Side Deck is present; no post-side plan can be evaluated

Why it scores here

The deck is an Illegal 55-card OCG list: three cards exceed their copy limits (Seventh Tachyon at 3 versus 1 allowed, Ash Blossom and K9-17 Izuna at 3 versus 2), so it does not receive a normal Final score and is capped at 20. Its structural read comes from the system as a whole: 13 hand-trap or negation-text cards, 19 removal-text cards and a 15-card Xyz Extra Deck give it real interaction density and a plausible going-second plan, while a 3-copy searcher density (about 0.76 chance of at least one searcher in an opening 5) keeps Engine Accessibility moderate. The score does not come from K9 being a popular archetype (usage stats show only 5 of 13 core cards present, and exact-name purity is 7.1%) and it was not produced by averaging the card scores. The deck has no recorded combos, no Side Deck and no tournament record, so the combo ceiling, median and post-side dimensions are text-based and Inferred, and the meta read is Provisional.

Dimension scores

How the score was computed

Strategy profile: Midrange. Structural ≈ 53, Going First ≈ 50, Going Second ≈ 58, Meta = provisional, Tournament Reliability ≈ 42. Modifiers: banlist exposure (-6); no side deck (-4). Final formula: No reliable metagame: 0.80*Structural + 0.20*TournamentReliability = 51 before modifiers; modifiers -10 give 41; capped at 20 because the deck is Illegal (three copy-limit violations), so the result is theoretical/structural-only

Probability & combo summary

• Opening a starter: P(≥1) ≈ 0.25 · 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

• 13 hand-trap or negation-text cards give layered interaction against the opponent's starter and engines
• 15 Xyz Extra Deck slots with strong closers (Number C104, Masquerade V, Number 39 monsters)
• Searcher density (13 searcher-text cards) gives good access to the Umbral Horror and Barian's engines

Weaknesses

• Illegal list: three cards over their copy limits
• Weak archetype identity (exact K9 purity 7.1%; only 5 of 13 K9 core cards present)
• No Side Deck and no recorded combos to read a combo floor or median
• High complexity: 15 Xyz and 13 hand traps create many decision points

Critical choke points

• Xyz summons depend on Masquerade and Number monsters in the Extra Deck, so one opposing negate or destruction can break the closer line
• Searchers are three-copy staples and the legal copy limits remove one or more per card
• Hand traps are the sole protection; a board without hand traps has no follow-up

Recommended changes

Evidence & confidence

• Verified: Deck is Illegal: Seventh Tachyon 3/1, Ash Blossom 3/2, K9-17 Izuna 3/2 (OCG BanList); Main 55 and Extra 15 are within OCG size rules; side is 0; Exact K9 name purity 7.1%; 65 off-archetype copies; 13 hand-trap-text, 13 searcher-text, 13 negation-text and 19 removal-text cards
• Observed: Archetype usage shows 5 of 13 K9 core cards present (38.5%)
• Inferred: Going-second plan rests on hand-trap draws (P ≈ 0.82 in 6 cards); Searcher access P ≈ 0.76 in opening 5; Interaction density is high from card text; Consistency and brick rates from the hypergeometric estimates
• Provisional: Meta Power and D13 matchup fit: no dated metagame sample or tournament link
• Data gaps: no combos supplied — combo floor/median/ceiling is text-only inference no tournament link — archetype meta-share and per-pilot match record absent no Side Deck (Side Deck size 0) — post-side and D12 are not evaluable no win-rate telemetry — going-first/second and matchup signals are Inferred or Unknown Meta Power is Provisional unless a dated metagame sample is supplied
