Memento Deck #774322 — Yu-Gi-Oh! Master Duel

Deck — Deck Power Evaluation

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

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

Legality

Main 40 / Extra 15 / Side 0 — status under the rules at evaluation time: Illegal. 1 violation(s).

Identity & game plan

• Win condition: Memento one-card combo into Mementoal Tecuhtlica - Combined Creation (5000 ATK) and Mementomictlan Tecuhtlica - Creation King (3000 ATK) Fusion/Special Summon lines; Mementotlan-Horned Dragon and Mementotlan Twin Dragon as board follow-up; Fusion lines via Mementotlan Fusion and Super Polymerization
• Turn 1 (going first): Open with Memento searchers (Angwitch, Bone Party, Ghattic, Akihiron) to reach a Memento engine monster, then Fusion or one-card Special Summon toward the Tecuhtlica boss (Inferred, text-only)
• Turn 2 (going second): Hold Ash Blossom, Nibiru and Forbidden Droplet/Crown as disruption, then rebuild through GY Memento recursion (Inferred)
• Recovery: Recover Memento monsters from the GY via Mementotlan Ghattic, Akihiron and Bone Party; banish-cost effects of Creation King and Bone Party (Inferred from text)
• After siding: No Side Deck is registered (side 0); no post-side plan can be evaluated

Why it scores here

The Structural score comes from the system: archetype core access (P(at least one Memento core card in a 5-card opening hand) ≈ 0.997; P(at least one searcher-text card) ≈ 0.877) and four hand traps plus negation text give it an accessible starter and some interaction, while the Extra Deck supplies large boss attackers. Median output and bricks are weaker: only 40% of the Main Deck is exact Memento, with 33 off-archetype copies, and several Memento boss requirements depend on GY state. No combo boards were supplied, so ceiling and median are text-only inferences. Popularity from the archetype's usage stats was not credited as power, and card scores were not averaged. The deck is Illegal (Super Polymerization ×3 against a limit of 2), so the Structural score is reported as theoretical only and the final score is capped at 35.

Dimension scores

How the score was computed

Strategy profile: Combo. Structural ≈ 58, Going First ≈ 58, Going Second ≈ 52, Meta = provisional, Tournament Reliability ≈ 52. Modifiers: banlist exposure (-10); engine conflicts (-2). Final formula: Illegal cap applied: 0.80*58 + 0.20*52 = 56.8 before modifiers; modifiers total -12 (44.8); capped to theoretical/structural-only score 35 because the deck is Illegal

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

• Archetype core access is very high (P≈0.997 for at least one core card in a 5-card opening hand)
• Multiple Memento searchers (13 searcher-text cards) and GY recovery support consistent starts
• Four hand traps plus Forbidden Crown and Droplet give layered interaction
• Boss monsters with high ATK (Tecuhtlica 5000, Horned Dragon 2850, Twin Dragon 2800)

Weaknesses

• Illegal copy count: Super Polymerization ×3 against a limit of 2
• Only 40% exact archetype purity; 33 off-archetype copies create conflicting draws
• Extra Deck spans 9 archetypes, weakening engine cohesion
• No Side Deck registered, so no post-side plan

Critical choke points

• Super Polymerization copy count (illegal; must be cut to 2 before any normal score applies)
• Memento GY requirements for the Tecuhtlica bosses (5 other Memento with different names)
• Reliance on hand traps and negation text for early interaction

Recommended changes

Evidence & confidence

• Verified: Legality: Super Polymerization 3 copies vs 2 legal (Semi-Limited); Composition counts: 40 Main, 15 Extra, 0 Side; Card stats and card text excerpts for all listed cards; Usage stats: 12 of 25 core cards present
• Observed: Usage stats show core inclusion at 100% for listed core cards
• Inferred: Opening-hand consistency from hypergeometric draw tables; Going-first and going-second plans from card text; Interaction quality from text role hints
• Provisional: Meta Power (no dated metagame sample); Matchup and format fit (D13)
• 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, matchup, game-level, brick/starter/OTK rates) — those signals are Inferred or Unknown Meta Power is Provisional unless a dated metagame sample is supplied No Side Deck present; post-side performance unknown
