Identity & game plan

  • Win condition: Extra Deck Xyz/Fusion/Link beaters (Mementomictlan Tecuhtlica - Creation King, Mementotlan-Horned Dragon, Mementotlan Twin Dragon, K9-ØØ Hound) reached through K9 and Memento searchers and Fusion/Xyz summons; Direct-attack and board-pressure lines from Mementoal Tecuhtlica (5000 ATK) and K9 Xyz monsters, once a stable board is established
  • Turn 1 (going first): Opening search (Mementotlan Angwitch, Ghattic, Akihiron, Mementotlan Fusion or K9-66a Jokul) into a Fusion or Xyz beater, keeping Ash Blossom and Infinite Impermanence for the first opposing response
  • Turn 2 (going second): Hand traps (Ash Blossom x2, Infinite Impermanence x2) and Forbidden Droplet to answer the opponent's first board, then rebuild through searchers and GY recursion
  • Recovery: Mementotlan Ghattic and Mementotlan Akihiron recover Memento cards from the GY; Mementotlan Bone Party and Goblin Biker Grand Entrance rebuild the hand; Mementotlan Shleepy and Mementotlan Fusion add Extra Deck access
  • After siding: Not available: the deck runs no Side Deck (side_count 0), so there is no post-side plan in this list

Why it scores here

The list reliably opens a functional starter most of the time. Fifteen searcher-text cards give P(at least one searcher in a 5-card opening hand) of about 0.89, so the first search is usually available, though no full-copy starter is drawn often (a 3-copy starter is about 0.31 in hand). Interaction is the deck's strongest area: 4 hand traps, Harpie's Feather Duster, Crossout Designator, Forbidden Droplet and 24 removal-text cards give layered answers to the opponent's board, and the two Ash Blossoms give redundancy. Conversion is credible on paper, with 3000-2800 ATK Extra Deck beaters, but no recorded boards exist, so ceiling and median are text-based inference only and are scored separately rather than averaged. The score comes from consistency, interaction and resource recovery on the whole system; the archetype label 'K9' is not what earned points, since only 10 of 59 cards are exact-name K9 and 22 are Memento, and popularity earned nothing. The 0-card Side Deck and the Memento/K9 engine split pull the score down, and the lack of meta data keeps Meta Power provisional.

Dimension scores

# Dimension Score Evidence
D1 Engine Accessibility & Consistency 62 P(>=1 searcher in hand5) ~0.89; P(>=1 of a 3-copy starter in hand5) ~0.31; engine core split between Memento and K9 (Inferred)
D2 Opening-Hand Quality & Brick Management 58 19 singleton slots and 19 non-monster cards in 44; redundancy from 15 searchers, but some hands will be dead or conflicting (Inferred)
D3 Combo Conversion & Ceiling 60 Extra Deck beaters (Creation King 3000, Horned Dragon 2850, Twin Dragon 2800) and multi-step Memento chains; no recorded boards, so text-only read (Inferred)
D4 Combo Floor & Median Output 48 No combos_evidence; median output estimated from starter diversity and 0-card side only, with low confidence (Inferred)
D5 Interruption Resilience & Route Redundancy 62 4 hand traps, 2 Ash Blossom copies and 15 searchers give alternative routes after one disruption (Inferred)
D6 Resource Economy, Recovery & Grind 65 Recursion from GY (Ghattic, Akihiron, Bone Party, Grand Entrance) and searchers allow rebuilds across turns (Inferred from card text)
D7 End-Board & Interaction Quality 70 24 removal-text and 8 negation-text cards; Duster, Crossout Designator and Infinite Impermanence cover the field; layering is semantic read (Inferred)
D8 Going-Second & Board-Breaking Power 60 Going-second split not recorded; hand traps and Forbidden Droplet answer boards, but hand6 hand-trap coverage is only about 0.46 (Inferred)
D9 Offensive Pressure & Closing Power 68 Creation King 3000 ATK, Horned Dragon 2850, Twin Dragon 2800, Lupis 2300 and K9-17 Ripper 2300 give closing power (Verified stats, Inferred conversion)
D10 Main Deck Efficiency & Flexibility 50 44 main cards with 30 distinct; purity 16.9% exact name; mixed sub-archetypes reduce coherence (Verified composition, Inferred efficiency)
D11 Extra Deck Efficiency & Coverage 60 15 of 15 Extra slots used across Fusion (5), Xyz (8) and Link (2); summon access depends on several enablers (Verified composition)
D12 Side Deck Adaptability 10 Side deck is empty (0 cards), so no post-side adaptation is available in best-of-3 (Verified)
D13 Matchup Coverage & Format Fit 45 No tournament link or dated meta sample; archetype usage shows K9 core about 53% present, which is context only (Provisional)
D14 Pilotability & Error Tolerance 45 Multiple engines (Memento, K9, Fusion, Xyz) and several decision points per turn make the deck demanding to pilot (Inferred)

How the score was computed

Strategy profile: Midrange. Structural ≈ 57.5, Going First ≈ 58, Going Second ≈ 52, Meta = provisional, Tournament Reliability ≈ 52. Modifiers: No side deck (-2); Banlist exposure (-1); Engine conflict (-2). Final formula: 0.80*Structural + 0.20*TournamentReliability + ContextModifiers (Meta provisional; no dated metagame sample)

Probability & combo summary

  • Opening a starter: P(≥1) ≈ 0.89 · 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

  • Layered interaction: 4 hand traps, Harpie's Feather Duster, Crossout Designator and Forbidden Droplet
  • Dense searcher text (15 cards) gives a high chance of a first search
  • Extra Deck beaters with high ATK (2800-3000) and multiple summon routes
  • Strong GY recursion from Ghattic, Akihiron, Bone Party and Grand Entrance

Weaknesses

  • No Side Deck, so no post-side adaptation
  • Low archetype purity (16.9% exact K9) with an engine split between Memento and K9
  • Heavy copy-limit exposure: five Limited cards run at 1 copy and Jokul is one of the key Extra enablers
  • Hard to pilot: several Extra Deck summon routes and multi-step Memento chains per turn

Critical choke points

  • Single copies of Mementomictlan Tecuhtlica - Creation King enablers; losing the Memento monster base shuts down Fusion access
  • Single copy of Harpie's Feather Duster and Crossout Designator for field-wide and card-specific answers
  • Opening hand with no searcher or starter (about 0.11 chance per hand with a single-copy starter)
Priority Remove Add Reason
1 One copy of Mementotlan Mace or a single-copy Memento filler A second copy of a K9 or Memento starter that is already in the deck, or a Side Deck of 3-8 cards A Side Deck is the largest structural gap (D12=10) and affects best-of-3 play
2 A low-impact tech card (for example one Goblin Biker Grand Breakout) A K9 enabler to raise exact-name purity and reduce engine split Current mix dilutes the K9 core (only 8 of 15 usage-core cards present)

Evidence & confidence

  • Verified: Main deck 44 cards and Extra deck 15 cards, within OCG size rules; All restricted cards run within legal copy limits (Limited at 1, Semi-Limited at 2); 0 side cards; Composition: 5 Fusion, 8 Xyz, 2 Link in Extra; 16 Spells and 3 Traps in main
  • Observed: Usage statistics: K9 core present 8 of 15 (53.3%)
  • Inferred: Hypergeometric starter access and searcher probability; Interaction layering from card text; Consistency and brick risk; Going-second hand-trap coverage (about 0.46)
  • Provisional: Meta power and matchup fit (no dated metagame sample); Tournament reliability inputs for post-side and matchup variance
  • 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 win-rate telemetry exists in YGOVN — going-first/second and brick/starter rates are Inferred Meta Power is Provisional unless a dated metagame sample is supplied deck title is null, so deck identity rests on the archetype label and card list
