K9 Deck #736002 — Yu-Gi-Oh! OCG

Deck — Deck Power Evaluation

Final Contextual Deck Power: 38/100 (±8 · Confidence: Low)

• Primary strategy: Combo
• Secondary strategies: Midrange, Interaction
• Format: ocg

Legality

Main 54 / Extra 18 / Side 0 — status under the rules at evaluation time: Illegal. 1 violation(s).

Identity & game plan

• Win condition: XYZ Summon K9 Xyz monsters to establish board pressure and interaction through detach-based removal and searches; Synchro Summon Crystron bosses for grind value and recovery; hand traps to disrupt opponent setup
• Turn 1 (going first): Establish Level 5 XYZ board (K9-17 Ripper, K9-66X Jacks) or Synchro access with Crystron Tuners for interruption; search K9 core via boss monsters
• Turn 2 (going second): Use hand traps (Ash, Impermanence, Evenly Matched, Nibiru) to slow opponent combo; break board with Forbidden Droplet or Evenly Matched
• Recovery: Crystron Inclusion search on field; GY banish recursion via Sulfador/Sulfefnir; Mulcharmy draw engine when opponent fills field
• After siding: Unknown — no side deck supplied; cannot assess transformational flexibility

Why it scores here

This K9 hybrid deck suffers from severe structural liabilities that prevent it from reaching a functional competitive level. The deck is illegal in OCG format — it runs 54 main deck cards (exceeds the 40-60 range boundary interpretation issue, but more critically, the 18-card Extra Deck exceeds the 15-card OCG limit by 3 cards). Beyond legality, the list is unfocused: it combines K9 XYZ core (15.3% exact archetype purity), Crystron Synchro lines, and generic hand traps without coherent synergy. K9-specific engines (K9-17 Izuna, K9-66a Jokul, K9-ØØ Lupis) lack redundancy — only 1 copy each — while the deck runs 3x Crystron Sulfefnir and 3x Sulfador, creating a tension between going-first Synchro setup and going-second XYZ pivot. No combo evidence is supplied, so all combo claims are inferred from card text: best outcome is likely a Synchro boss into XYZ overlay, but median boards (lacking starter diversity) are modest and fragile. The deck runs 14 hand traps but no side deck (0/15), leaving post-side adaptation unknown. With an illegal extra deck, missing core K9 consistency pieces, and no tested combo framework, this list scores below threshold.

Dimension scores

How the score was computed

Strategy profile: Combo. Structural ≈ 48, Going First ≈ 52, Going Second ≈ 68, Meta = provisional, Tournament Reliability ≈ 42. Modifiers: Illegality penalty (-12); Oversized main deck (-4); Missing core K9 cards (-3); No side deck (-2). Final formula: Illegal deck capped at 38; 0.80*Structural (48) + 0.20*TournamentReliability (42) + Legality penalty (-12) = 38 (Meta provisional, no metagame sample supplied)

Probability & combo summary

• Opening a starter: P(≥1) ≈ 0.73 · key two-card combo ≈ — · full-brick estimate ≈ 0.15 (all Inferred)
• Combo output: best PowerIndex —, median —, board-per-starter —
• Turn order: 0 going-first lines vs 0 going-second lines

Strengths

• Going-second tool density: 3x Evenly Matched, 3x Ash, 3x Impermanence, 3x Forbidden Droplet provide broad hand-trap and board-breaker coverage
• K9 XYZ detach value: K9-66X Jacks and K9-X Werewolf deliver repeatable removal and multi-attack scaling
• Crystron recursion engine: Sulfefnir, Sulfador, and Inclusion supply GY recovery and resurrection for extended grind
• Searcher redundancy: 13 cards with searcher text hint enable consistent tutoring for K9 and Crystron pieces
• Hand-trap frequency: 14 hand-trap copies ensure high going-second disruption likelihood

Weaknesses

• CRITICAL: Deck is illegal in OCG format — 18-card Extra Deck exceeds 15-card maximum by 3 cards; unplayable as submitted
• Engine conflicts: Crystron Synchro lock (Smiger/Thystvern forbid Extra Deck except Machine Synchro) prevents smooth pivot to K9 XYZ on same turn
• Low K9 core redundancy: Only 1-2 copies of key K9 starters (Jokul, Lantern, Lupis); single interruption collapses line
• Oversized main deck: 54 cards vs 40-card optimal baseline reduces consistency; hand-trap density (14 copies) competes with engine slots
• No independent combo lines: Starter diversity is low; median boards inferred as modest (1-2 pieces) without documented frequency
• Missing archetype core: Lacks K9-X Werewolf (61% meta inclusion), K9-17 Ripper (50%), S:P Little Knight (61%); only 54.5% core presence vs meta standard
• No going-first close: Highest offensive ATK is K9-ØØ Lupis 2300; Crystron Quariongandrax 3000 ATK is hard to reach; no OTK or piercing mechanics
• Extra Deck bloat: 18 cards with many niche slots (Chronomaly Vimana, Infinitrack River Stormer, Skyblaster TY-PHON) rarely summoned

Critical choke points

• Legality violation: 18-card Extra Deck is unplayable in OCG; deck cannot legally compete
• Engine lock conflict: Crystron Smiger/Thystvern restrict Extra Deck to Machine Synchro, blocking pivot to XYZ strategy mid-turn
• K9 starter scarcity: Jokul Limited (1 copy), Lantern 1 copy, Lupis 1 copy; loss of one K9 starter leaves combo line broken
• No metagame data: No tournament link, no win rates, no matchup outcomes; Meta Power is unquantifiable
• Combo frequency unknown: No boards supplied; ceiling and median are inferred from text, not observed from play data

Recommended changes

Evidence & confidence

• Verified: Legality status: Illegal (Extra Deck 18 > 15 OCG max); Main deck size: 54 cards (exceeds typical 40-60 midpoint guidance); Card text parsed for all 45 distinct main cards and 17 Extra Deck cards; Banlist status: Limited cards (Jokul 1x, A Case for K9 1x, Called by Grave 1x, Solemn Judgment 1x); Semi-Limited (Droll & Lock Bird 2x); Archetype composition: 15.3% K9 exact-name, 26.4% Crystron, 58.3% generic/tech; Usage statistics available: 54.5% K9 core presence (6/11 core cards); missing Maxx C (65.4%), K9-X Werewolf (61.5%), S:P Little Knight (61.5%)
• Observed: Archetype meta inclusion: K9-ØØ Lupis 80.8%, K9-66a Jokul 73.1%, Ash Blossom 61.5%, K9-17 Izuna 61.5% across sampled meta builds
• Inferred: P(≥1 K9 or Crystron core in opening 5): ~0.73 from hypergeometric K9 core group (archetype core.p_open_at_least_one_hand5); P(≥1 hand trap in opening 6): ~0.85 from 14 hand-trap copies (hand_trap_group.p_at_least_one_hand6_going_second); Combo ceiling inferred from K9-17 Izuna hand effect into XYZ Summon (K9-66X Jacks detach destroy); Crystron Synchro bootstrap via Sulfefnir; ceiling ~3-4 interaction pieces; Combo median inferred as narrow (1-2 interaction pieces) due to low starter diversity and engine lock conflicts; Going-second resilience: Evenly Matched, Ash Blossom, Impermanence, and Forbidden Droplet provide tools but no documented win rate vs meta field boards; Offensive closing power inferred from K9 ATK values (Lupis 2300, Jacks 2600, Werewolf 3300) and Crystron Quariongandrax 3000; no piercing or OTK listed; Engine lock conflict: Crystron Smiger/Thystvern restrict Extra Deck Summons to Machine Synchro per turn, blocking XYZ pivot; Resource economy estimated as modest grind capacity via Inclusion recursion and Mulcharmy draw engine; net resource advantage unclear without play data
• Provisional: Meta Power: null (no dated metagame sample, no tournament link for pilot records); Matchup outcomes: unquantified (no tournament context available); Post-side transformation: unknown (0 side deck cards supplied; D12 scored 0 by default)
• Data gaps: No combo boards supplied — combo floor, median, ceiling, and per-starter power are text-only inferences, not observed frequencies No tournament link — archetype meta-share and per-pilot match record absent; Meta Power is Provisional No win-rate telemetry (game-level, matchup, going-first/second brick rates) — only hypergeometric probabilities available No side deck supplied (0/15) — post-side plan and best-of-3 transformation unknown No playtest frequency data — cannot validate inferred combo floor/median against real distribution Deck is illegal in OCG format (Extra Deck 18 > 15); evaluation is structural-only pending legality correction
