Memento Deck #772861 — Yu-Gi-Oh! OCG

Deck — Deck Power Evaluation

Final Contextual Deck Power: 30/100 (±8 · Confidence: Low)

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

Legality

Main 55 / Extra 15 / Side 0 — status under the rules at evaluation time: Illegal. 3 violation(s).

Identity & game plan

• Win condition: Memento board-presence plus Mementoal Tecuhtlica - Combined Creation (5000 ATK, 1 copy) and the Memento Fusion/Link Extra Deck boss monsters (Creation King, Twin Dragon, Horned Dragon); Mementotlan Fusion and Mementotlan Bone Party recursion into repeated Memento Fusion summons
• Turn 1 (going first): Open on Memento searchers (Angwitch, Bone Party, Ghattic, Akihiron) to reach a Memento monster and build toward Fusion or Link summons; hand traps and Ash Blossom are held for the opponent's first activation
• Turn 2 (going second): Use Droll & Lock Bird and Ash Blossom to slow the opponent's first draw or search, then rebuild through Memento graveyard recursion
• Recovery: Recover Memento cards from the GY with Ghattic, Mementotlan Fusion and Creation King's GY banish effect; the deck has enough searchers to rebuild after one interruption (text-level inference only)
• After siding: Not evaluable: Side Deck size is 0 and no post-side data exists

Why it scores here

The Memento core is nearly always reachable: P(at least one archetype-core card in a 5-card opening hand) is about 0.99 (Inferred), and the deck runs 13 searcher-text cards, so the starter is accessible. Consistency is held back by 5 hand traps and several conditional effects that only work in specific board states. Interaction (Droll, Ash Blossom, Forbidden Droplet, Lightning Storm, Harpie's Feather Duster, Cranium Burst) and GY recursion give it a reasonable resilience profile on paper. The score is not driven by Memento's popularity (usage stats only confirm the list is a real archetype build) and card scores were not averaged. The deck is Illegal (three cards over the OCG copy limit), so the structural score of about 57 is theoretical and the final score is capped at 30.

Dimension scores

How the score was computed

Strategy profile: Midrange primary, Combo as secondary (no separate blend computed). Structural ≈ 57, Going First ≈ 55, Going Second ≈ 55, Meta = provisional, Tournament Reliability ≈ 42. Modifiers: banlist exposure (-12); illegal_deck_cap (0). Final formula: Pre-cap: 0.80*57 + 0.20*42 = 54; modifiers -12 gives 42; Illegal cap applied, final 30 (theoretical/structural only, Meta provisional)

Probability & combo summary

• Opening a starter: P(≥1) ≈ 0.99 · key two-card combo ≈ — · full-brick estimate ≈ 0.01 (all Inferred)
• Combo output: best PowerIndex —, median —, board-per-starter —
• Turn order: 0 going-first lines vs 0 going-second lines

Strengths

• Archetype core is nearly always accessible in the opening hand (Inferred)
• Layered interaction across hand traps, backrow removal and negation text (Inferred)
• Recursion through Memento GY effects supports a long game (Inferred)

Weaknesses

• Illegal copy-limit counts make the list unplayable as built
• Five hand traps and many conditional effects raise brick and misplay risk (Inferred)
• Zero side deck limits post-game adaptation
• Extra Deck is full with several boss options that need conditional access (Inferred)

Critical choke points

• Mementoal Tecuhtlica - Combined Creation is a single copy and is the top ceiling threat
• Droll & Lock Bird and Ash Blossom are over the limit and must be cut to legal counts

Recommended changes

Evidence & confidence

• Verified: Deck is Illegal: 3 cards over OCG copy limit; Main 55 / Extra 15 / Side 0 are within OCG size rules; Archetype is Memento; Memento core is 33 copies
• Inferred: Starter access ≈ 0.99 for the archetype core; Interaction layering and recursion estimated from card text; Structural score ≈ 57 from the Midrange profile
• Provisional: Meta power is null; no dated metagame sample; Tournament reliability ≈ 42 without match data; Matchup fit is provisional
• 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 side deck — post-side plan cannot be evaluated no win-rate telemetry — going-first/second, matchup and brick rates are Inferred or Unknown Meta Power is Provisional unless a dated metagame sample is supplied
