Memento Deck #752007 — Yu-Gi-Oh! Master Duel

Deck — Deck Power Evaluation

Final Contextual Deck Power: 55/100 (±8 · Confidence: Low)

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

Legality

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

Identity & game plan

• Win condition: Memento one-card starter (Mementotlan Angwitch, Fusion, Bone Party, Tatsunootoshigo) converting into Fusion Summons of Mementomictlan Tecuhtlica - Creation King (3000 ATK) and Mementotlan Twin Dragon (2800 ATK) (Inferred from card text); Grinding through Memento recursion (Ghattic, Akihiron, Mementomictlan, Creation King) and Forbidden Crown / hand-trap interaction (Inferred)
• Turn 1 (going first): Open a Memento starter, search or Fusion Summon into a Creation King or Twin Dragon, and use Mace or Dark Blade to clear backrow (Inferred)
• Turn 2 (going second): Use hand traps Ash Blossom, Droll and Maxx C to break the opponent's first line, then recover Memento monsters from the GY (Inferred)
• Recovery: Ghattic and Akihiron return Memento cards from the GY; Creation King banishes from the GY to add Mementomictlan (Inferred from card text)
• After siding: None. The side deck is empty (0 of 15 slots), so there is no post-side plan.

Why it scores here

The deck reliably opens a Memento starter (about 99% for at least one archetype-core card in a 5-card hand, a proxy estimate) and has several redundant one-card starters, so its first turns are accessible. Its interaction is layered across hand traps (Ash Blossom, Droll and Lock Bird, Maxx C), Forbidden Crown, and Memento removal and control effects, and it recovers through GY recursion (Ghattic, Akihiron, Creation King). Its closing power comes from extra-deck boards at 2800 to 3300 ATK, but the one-card line is held back by conditional summons such as Mementoal Tecuhtlica needing five other Memento monsters, and by 35 of 55 copies sitting outside the exact Memento name. No combo recordings exist, so the floor and median are not measured and the score rests on text and probability inference. Popularity and archetype usage did not earn points, and the score was not an average of card scores.

Dimension scores

How the score was computed

Strategy profile: Combo. Structural ≈ 61.8, Going First ≈ 65, Going Second ≈ 60, Meta = provisional, Tournament Reliability ≈ 55. Modifiers: banlist exposure (-1); engine conflict / low purity (-2); no post-side plan (-2). Final formula: 0.80*Structural + 0.20*TournamentReliability + ContextModifiers (Meta provisional, no dated sample): 0.80*61.8 + 0.20*55 - 5 = 55.4

Probability & combo summary

• Opening a starter: P(≥1) ≈ 0.99 · 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

• Several redundant one-card Memento starters (Angwitch, Bone Party, Tatsunootoshigo, Fusion) at 3 copies each
• Layered interaction: hand traps, Forbidden Crown, Memento removal and control effects
• Strong GY recursion, which supports recovery across turns
• Extra-deck closers at 2800 to 3300 ATK

Weaknesses

• Low exact-name purity (36.4%) with many off-archetype copies that compete for hand space
• No side deck, so no adaptation across games
• Conditional cards (Tecuhtlica, Mementomictlan) add brick risk
• No measured combo, brick, or matchup data

Critical choke points

• Memento monsters must be in hand or GY for Fusion and Tecuhtlica; if they are not, the line stalls
• Single-copy Tecuhtlica depends on five distinct Memento monsters being available

Evidence & confidence

• Verified: Main 40 / Extra 15 / Side 0 within MasterDuel size rules; All restricted cards within legal copies (Maxx C 1/1, Droll 2/2, Super Polymerization 2/2, The Fallen and the Virtuous 2/2); Copy histogram and extra-deck breakdown (10 Fusion, 4 Link, 1 Synchro); Exact-name Memento purity 36.4%
• Inferred: Starter access and redundancy (D1); Recursion and recovery from card text (D5, D6); Interaction breadth from card text (D7); Going-second hand-trap coverage (D8); Closing power from extra-deck ATK (D9)
• Provisional: Meta power is null (no dated metagame sample); Matchup and format fit (D13) is held at 50; Floor and median (D4) are held at 50 with no combo data
• Data gaps: No combos supplied: combo floor, median and ceiling are text-only inference (combo data total 0) No tournament link: archetype meta-share and per-pilot match record absent No win-rate telemetry (going-first/second, matchup, brick, starter rates) Meta Power is Provisional unless a dated metagame sample is supplied usage statistics extra-deck flags conflict with the card list: Creation King, Twin Dragon, Garura, Guardian Chimera, S:P Little Knight and others show in this deck=false although they appear in the extra zone, so the 44% core_present figure is unreliable Deck title is null, so the deck name is unknown Side deck is empty; no post-side data exists
