K9 Deck #751258 — Yu-Gi-Oh! TCG

Deck — Deck Power Evaluation

Final Contextual Deck Power: 30/100 (±8 · Confidence: Low)

• Primary strategy: Midrange
• Secondary strategies: Toolbox, Combo
• Format: tcg

Legality

Main 55 / Extra 15 / Side 0 — status: Illegal. 10 violation(s).

Identity & game plan

• Win condition: Synchro-based beatdown from Elfnote and Power Patron monsters (e.g. Elfnote June Pride, Junora the Power Patron of Tuning, Chaos Angel) once the Extra Deck is live; Vidolium the Unstable Power Patron of Unity (5000 ATK) as a single pendulum threat, if its level-12 condition is met
• Turn 1 (going first): Open a Tuner or Elfnote starter and search toward a Synchro; interaction is held back for the opponent's turn
• Turn 2 (going second): Hold Ash Blossom, Ghost Ogre, Ghost Belle, Droll and Solemn to answer the opponent's first summon or activation, then rebuild a board with Elfnote or Power Patron monsters
• Recovery: Mulcharmy and Elfnote recursion plus searchers, but recovery depends on a live Extra Deck, which the illegal list weakens
• After siding: None: the Side Deck is empty, so there is no post-side plan (and a best-of-3 side plan is not meaningful for an illegal list)

Why it scores here

The deck is scored as a system, not as an average of its cards. It is strong on interaction: nine hand traps, four Solemn-family cards, Forbidden Crown and Harpie's Feather Duster give it layered answers, and the Synchro ceiling (Junora, Chaos Angel, June Pride, Vidolium) is real. Consistency is weak: only 5.7% of the list shares the exact K9 name, the deck mixes Elfnote, Power Patron, Mulcharmy and K9 engines, and P(at least one of a given 3-copy card in a 5-card hand) is only about 0.25. Combo evidence is absent, so the floor, median and ceiling are text-based inferences only. The list is illegal: five Forbidden cards and five over-limit entries cap the score, and the deck has no Side Deck. The popularity of the K9 archetype does not earn points here.

Dimension scores

How the score was computed

Strategy profile: Midrange primary, Toolbox secondary (structural weights from the Midrange row). Structural ≈ 52, Going First ≈ 48, Going Second ≈ 52, Meta = provisional, Tournament Reliability ≈ 40. Modifiers: banlist_exposure (-10); engine_conflicts (-2). Final formula: No reliable metagame: 0.80*Structural(52) + 0.20*TournamentReliability(40) = 49.6; modifiers -12 gives 37.6; deck is Illegal, so the score is capped at 30 and labelled structural-only

Probability & combo summary

• Opening a starter: P(≥1) ≈ 0.83 · key two-card combo ≈ — · full-brick estimate ≈ 0.17 (all Inferred)
• Combo output: best PowerIndex —, median —, board-per-starter —
• Turn order: 0 going-first lines vs 0 going-second lines

Strengths

• Layered interaction: nine hand traps, four Solemn-family cards, Forbidden Crown and Harpie's Feather Duster
• High Synchro and Power Patron closing power (Vidolium 5000 ATK, Chaos Angel 3500 ATK, Junora 3100 ATK)
• Searcher and recursion text (16 searcher-text cards, Mulcharmy draw effects) supports grind

Weaknesses

• Illegal list: five Forbidden cards and ten over-limit entries
• Mixed engines (Elfnote, Power Patron, Mulcharmy, K9) with 5.7% exact-archetype purity
• Empty Side Deck, so no post-side plan
• No recorded combos, so ceiling and median are unverified

Critical choke points

• A live Extra Deck is needed for almost every Synchro line; the Forbidden Extra Deck cards are removed, so the usable Extra Deck is 12 cards
• Elfnote starters (Power Patron, Lucina, Regina, Tinia) are the main engine; Tinia is Forbidden and Lucina is capped at one copy

Recommended changes

Evidence & confidence

• Verified: Legality status Illegal with 10 violations (Forbidden and over-limit cards); Main 55, Extra 15, Side 0 (within size rules); Card stats and text excerpts from evidence; Archetype core usage stats (7 of 22 core cards present)
• Inferred: Consistency estimates from hypergeometric probabilities (0.25 per 3-copy card; 0.83 archetype core); Brick and hand-trap estimates; Interaction and resilience scores from card text; Going-first and going-second estimates
• Provisional: Meta Power (null); Matchup and format fit (D13)
• Data gaps: Illegal list: copy-limit and Forbidden-card violations make the score structural-only and capped No combos supplied: combo floor, median and ceiling are text-only inference No tournament link: archetype meta-share and match record are absent No Side Deck: post-side adaptability is unknown Usage-statistics inconsistency: Number C104: Umbral Horror Masquerade (49456901) is in the Extra Deck list but usage_statistics reports in_this_deck=false and lists it under missing_core; verify this record No win-rate telemetry exists in YGOVN, so brick, starter, going-first and matchup rates are Inferred or Unknown Meta Power is Provisional unless a dated metagame sample is supplied
