K9 Deck #770446 — Yu-Gi-Oh! TCG

Deck — Deck Power Evaluation

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

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

Legality

Main 55 / Extra 15 / Side 0 — status under the rules at evaluation time: Illegal. 6 violation(s).

Identity & game plan

• Win condition: Xyz boards (K9 Xyz monsters and Number C104 / Red-Eyes Exceed) built on hand-trap-protected turns, closing with 3000+ ATK attackers.; Recovering from hand-trap exchanges through K9 searchers and Dark Time Wizard recursion.
• Turn 1 (going first): Open a K9 or Mulcharmy starter, use a searcher to find a second K9 piece, and build toward a K9 Xyz while holding a hand trap for the opponent's first interaction.
• Turn 2 (going second): Use a hand trap (Ash Blossom, Ghost Ogre, Skull Meister, Effect Veiler) on the opponent's starter, then Normal Summon an Izuna or Lantern to stabilise and continue into a K9 Xyz.
• Recovery: Re-search a K9 monster with A Case for K9 or K9-17 Ripper's effect and rebuild the Xyz from the Extra Deck, using Mulcharmy draws to refill the hand.
• After siding: No Side Deck is registered, so there is no post-side plan; the deck cannot adapt between games in a best-of-3 event.

Why it scores here

The deck is scored as a system, not as an average of its 70 card scores. Its K9 and Mulcharmy openers have a high chance of producing a starter, with P(at least one archetype-core card in a 5-card hand) about 0.91, so it opens functional hands often (Inferred). Its 17 hand traps and 13 negation-text cards give it strong interaction on the opponent's first turn, and its Xyz bosses (Red-Eyes Exceed 3400 ATK, Number C104, K9-X Werewolf) give it real closing power once a board is established (Inferred). Floor and median output cannot be measured: there are no recorded boards, so combo conversion is text-only and marked Inferred. Popularity did not earn points: the archetype usage stats only confirm that the core cards are standard. The deck is Illegal (three Forbidden cards and three cards over their copy limits), so the score is capped and the evaluation is structural only, with no Side Deck and no matchup data.

Dimension scores

How the score was computed

Strategy profile: Midrange. Structural ≈ 55, Going First ≈ 55, Going Second ≈ 58, Meta = provisional, Tournament Reliability ≈ 45. Modifiers: banlist_exposure (-8). Final formula: No reliable metagame, so Meta is provisional: Final = 0.80*55 + 0.20*45 = 53, then Illegal cap to 35 (Illegal decks receive no normal Final score); the cap is a structural-only ceiling, not a modifier

Probability & combo summary

• Opening a starter: P(≥1) ≈ 0.91 · 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 interaction: 17 hand traps, 13 negation-text cards and 20 removal-text cards
• Strong Xyz closers (Red-Eyes Exceed 3400, Number C104 3000, K9-X Werewolf 3300)
• High probability of a core K9 card in the opening hand (about 0.91)

Weaknesses

• Illegal in its current form: three Forbidden cards and three cards over their copy limit
• Split engines (K9, Dark Time Wizard, Mulcharmy) with 17% exact-archetype purity
• No Side Deck, so no post-side adaptability
• No recorded boards, so the combo ceiling and median cannot be measured

Critical choke points

• Reliance on the 20-card K9 core for a Xyz board, with no recorded alternative line
• Forbidden and over-limit cards (Called by the Grave, Crossout Designator, Triple Tactics Talent, Ash Blossom and Izuna at 3 copies, Droll at 2 copies) must be removed before the list is legal

Recommended changes

Evidence & confidence

• Verified: Main Deck 55, Extra Deck 15, Side Deck 0 (legal size range); Forbidden status for Called by the Grave, Crossout Designator and Triple Tactics Talent; Semi-Limited for Ash Blossom and Izuna; Limited for Droll, Lock Bird and others; Usage stats: K9 core inclusion rates (Ash Blossom 97%, Izuna 93%, K9-ØØ Lupis 87%)
• Inferred: Opening-hand starter probability from hypergeometric draw odds; Hand-trap and interaction value from card text; Engine coherence across three archetypes
• Provisional: Meta Power (no dated metagame sample); Matchup 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 absent No win-rate telemetry (going-first/second, matchup, brick/starter rates) No Side Deck registered Meta Power is Provisional unless a dated metagame sample is supplied
