K9 Deck #770623 — Yu-Gi-Oh! TCG

Deck — Deck Power Evaluation

Final Contextual Deck Power: 35/100 (±10 · Confidence: Low)

• Primary strategy: Midrange
• Secondary strategies: Stun
• Format: tcg

Legality

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

Identity & game plan

• Win condition: Extra Deck Xyz/Link boss monsters from the K9 and Vanquish Soul sub-engines (K9-66X Jacks, Vanquish Soul Rocks, Vanquish Soul Caesar Valius on the main-deck side); board is built with monster-based Normal Summons and hand-trap-protected starters (Inferred from text).; Mulcharmy draw-engine pressure via the Mulcharmy monsters' draw effects when the opponent summons (Inferred from text).
• Turn 1 (going first): Open on K9-17 Izuna or K9-66b Lantern (Normal Summon without Tribute when the opponent holds 2+ cards), add a K9 or Vanquish Soul monster via A Case for K9 / Vanquish Soul, Start!, then build an Xyz with K9-X Forced Release or Vanquish Soul Rocks (Inferred).
• Turn 2 (going second): Use Ash Blossom, Ghost Belle, Droll & Lock Bird and the Solemn trio to stop the opponent's first summon or search, then rebuild the board through Mulcharmy draws and Vanquish Soul Heavy Borger or Caesar Valius (Inferred).
• Recovery: Rebuild from the searchers in the Main Deck (19 searcher-text cards, P(at least one in opening 5) approx. 0.89 per the evidence pack) and from the Mulcharmy draw effects after a board wipe (Inferred).
• After siding: No Side Deck is registered (side_count 0), so no post-side plan can be scored; D12 is held at a low value (Verified count, Inferred plan).

Why it scores here

This list is scored as an Illegal system, so its structure is shown but its power is capped. It runs three Ash Blossom, three Vanquish Soul Razen and three K9-17 Izuna where the banlist allows two, one and two copies, which is a hard legality failure. Its consistency comes from 17 archetype-core cards (P(at least one core card in an opening 5) approx. 0.86) that are split across two sub-engines (Vanquish Soul 20 cards, K9 13 cards) plus Mulcharmy, so the engine is coherent in parts but conflicted overall. Interaction is the strongest feature: Ash Blossom, Ghost Belle, Droll & Lock Bird, three Solemn-family cards and K9-X Forced Release give dense disruption (D7 72). Combo ceiling and median are text-only inferences because no boards were recorded, and no side deck is present. Archetype popularity did not earn points, and no card scores were averaged into the deck score.

Dimension scores

How the score was computed

Strategy profile: Midrange primary with Stun-leaning interaction; weights taken from the Midrange profile only, Stun not blended into the numbers (disclosed).. Structural ≈ 55, Going First ≈ 55, Going Second ≈ 58, Meta = provisional, Tournament Reliability ≈ 50. Modifiers: banlist_exposure (-6); engine_conflicts (-4). Final formula: No reliable metagame: 0.80*Structural + 0.20*TournamentReliability = 0.80*55.2 + 0.20*50 = 54.2; context modifiers -10 gives 44.2; Illegal legality cap applied (theoretical/structural only) gives 35.

Probability & combo summary

• Opening a starter: P(≥1) ≈ 0.86 · key two-card combo ≈ — · full-brick estimate ≈ 0.14 (all Inferred)
• Combo output: best PowerIndex —, median —, board-per-starter —
• Turn order: 0 going-first lines vs 0 going-second lines

Strengths

• Dense interaction: Ash Blossom, Ghost Belle, Droll & Lock Bird, three Solemn-family cards and K9-X Forced Release.
• High engine access: the 17-card archetype core is present in the opening 5 about 86% of the time (Inferred).
• Strong Extra Deck boss options (Caesar Valius 3000 ATK, Umbral Horror Masquerade 3000, Jacks 2600).

Weaknesses

• Illegal copy counts on three cards (Ash Blossom, Vanquish Soul Razen, K9-17 Izuna).
• Two competing sub-engines (Vanquish Soul and K9) with only 18.6% exact-archetype purity.
• No side deck and no recorded combos, so the post-side and combo ceiling are unmeasured.

Critical choke points

• Vanquish Soul Razen at 3 copies is a Limited-status choke over the legal limit of 1; the list cannot be played until it is cut.
• Single Xyz-material chain for the K9 bosses (inferred from text) becomes fragile if the starter is negated.
