Deck — Deck Power Evaluation

Final Contextual Deck Power: 62/100 (±6 · Confidence: Medium)

• Primary strategy: Combo
• Secondary strategies: Toolbox, Midrange
• Format: master-duel

Legality

Main 40 / Extra 15 / Side 0 — status: Legal.

Identity & game plan

• Win condition: One-card combo starters (Mementotlan Angwitch, Bone Party, Tatsunootoshigo, Shleepy, Ghattic, Akihiron, Mace, Dark Blade) that convert into Memento Fusion and Extra Deck boss monsters such as Mementomictlan Tecuhtlica - Creation King, Mementotlan Twin Dragon and Mementotlan-Horned Dragon.; Recursion and Special Summon loops out of the GY, backed by 6 hand traps (Ash Blossom, Ghost Belle, Nibiru) and Mementoal Tecuhtlica - Combined Creation as a 5000 ATK finisher.
• Turn 1 (going first): Open with a Memento searcher or starter (Angwitch, Bone Party, Ghattic), add a Memento monster, then Fusion Summon or Special Summon a Memento boss while holding Ash Blossom and Ghost Belle for the opponent's first interaction.
• Turn 2 (going second): Hold Ash Blossom, Ghost Belle or Nibiru in hand to stop the opponent's board or first search, then rebuild through GY recursion with Bone Party, Ghattic and Akihiron.
• Recovery: Recover from the GY with Mementotlan Ghattic, Mementotlan Akihiron and the banish-to-hand effect of Creation King, then re-run Fusion Summon through Mementotlan Fusion.
• After siding: Not applicable: Master Duel has no side deck (side_count 0), so there is no post-side plan to evaluate.

Why it scores here

The deck scores as a system: the Memento core (24 exact-name copies, 25-card archetype core with a 99.5 percent chance of at least one in a 5-card opening hand) gives a reliable starter density, so the engine comes online early. Its one-card combo starters, recursion effects and six hand traps let it keep pressure through a single interruption, and 4 of the 6 hand-trap and negation effects can hit a turn-1 play going second. The ceiling is set by the Creation King, Twin Dragon, Horned Dragon and Tecuhtlica boss monsters, but no recorded boards exist, so the floor and median are estimates from card text only. Popularity and the usage core confirm the list is real and accessible but earned no points, and card scores were not averaged into the deck score.

Dimension scores

How the score was computed

Strategy profile: Combo. Structural ≈ 65, Going First ≈ 66, Going Second ≈ 68, Meta = provisional, Tournament Reliability ≈ 62. Modifiers: Brick burden (-2); Off-archetype dilution (-1); Banlist exposure (0); Engine redundancy (1). Final formula: 0.80*Structural + 0.20*TournamentReliability (Meta provisional) + ContextModifiers(-2)

Probability & combo summary

• Opening a starter: P(≥1) ≈ 1 · 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 Memento core with 99.5 percent opening-hand access to an archetype card
• Six hand traps plus Ash Blossom, Ghost Belle and Nibiru give strong going-second interaction
• Recursion through Ghattic, Akihiron, Bone Party and Creation King keeps the deck alive after disruption
• Extra Deck bosses at 2800 to 5000 ATK give real closing power

Weaknesses

• No recorded boards, so the combo floor and median are unverified
• Low exact-name purity (43.6 percent) with 31 off-archetype copies
• Brick risk from quick-play filler and 3-copy staples
• No side deck, so the deck cannot adapt between games

Critical choke points

• Dependence on a Memento monster being on the field or in the GY for Fracture Dance, Bone Party and Creation King effects
• Creation King and Twin Dragon as the main Extra Deck boss copies (2 each)

Evidence & confidence

• Inferred: Opening-hand starter access is about 0.995 from hypergeometric estimate; Hand-trap access on a going-second 6-card hand is about 0.650; Combo ceiling and floor are read from card text only; Interaction density and recursion depth are read from card text
• Provisional: Meta Power (no dated metagame sample); Matchup and format fit (no tournament link)
• 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, going-second, matchup and brick rates are Inferred or Unknown Meta Power is Provisional unless a dated metagame sample is supplied Master Duel has no side deck, so post-side scoring is structural only
