Memento Deck #772339 — Yu-Gi-Oh! OCG

Deck — Deck Power Evaluation

Final Contextual Deck Power: 30/100 (±10 · Confidence: Low)

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

Legality

Main 51 / Extra 15 / Side 0 — status under the rules at evaluation time: Illegal. 1 violation(s).

Identity & game plan

• Win condition: Fusion and Link pressure from Mementotlan Twin Dragon, Mementomictlan Tecuhtlica - Creation King and Mementoal Tecuhtlica - Combined Creation, reached through Memento recursion and searchers; Mementotlan-Horned Dragon Special Summon from the GY once three differently named Memento monsters are there
• Turn 1 (going first): Open a Memento searcher (Angwitch, Ghattic, Akihiron) or Mementotlan Fusion, convert into a Memento Fusion or Link, and protect with Ash Blossom and Ghost Ogre
• Turn 2 (going second): Hand traps (Ash Blossom, Ghost Ogre, Droll & Lock Bird) on the opponent's starter, then rebuild through Memento GY recursion
• Recovery: Memento GY recursion through Bone Party, Ghattic and Akihiron, plus Mementomictlan's Special Summon from hand or GY
• After siding: Not available: the deck has no Side Deck, so there is no post-side plan

Why it scores here

The deck is Illegal because it runs three copies of Ash Blossom & Joyous Spring against a limit of two, so it receives only a capped, structural-only read. Its consistency rests on the Memento core, which is present in about 99.6% of opening hands (Inferred), and on 16 searcher-text cards, which give about 86% odds of at least one search in five cards. Interaction is the strongest system trait: seven hand traps, three Typhoons, Mystical Space Typhoon, and Ash Blossom and Ghost Ogre as repeatable responses. Its ceiling comes from text (Tecuhtlica 5000 ATK, Creation King, Twin Dragon) rather than recorded boards, and there is no combo evidence, so median output is weakly supported. Popularity and archetype usage did not earn points, and the card scores were not averaged into the deck score.

Dimension scores

How the score was computed

Strategy profile: Midrange. Structural ≈ 50, Going First ≈ 45, Going Second ≈ 50, Meta = provisional, Tournament Reliability ≈ 40. Modifiers: Banlist exposure (-4); No side deck (-4). Final formula: Illegal cap applied: 0.80*Structural(50) + 0.20*TournamentReliability(40) = 48; modifiers -8 gives 40; Illegal-deck cap (rubric Step 2) lowers the final to 30; Meta Provisional

Probability & combo summary

• Opening a starter: P(≥1) ≈ 0.27 · 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 (99.6% at least one in hand) with heavy searcher text
• Seven hand traps and three Typhoons give broad interaction
• Recursion through GY Memento monsters supports rebuilds

Weaknesses

• Illegal: Ash Blossom over copy limit
• Off-archetype split (34.8% exact-name purity) dilutes engine coherence
• No side deck and no recorded boards

Critical choke points

• Mementotlan Fusion and Memento Fusion summons depend on Extra Deck material
• Ash Blossom over-limit: a legal build must cut one copy

Recommended changes

Evidence & confidence

• Verified: Ash Blossom & Joyous Spring is over its copy limit (3 vs 2); Main 51, Extra 15, Side 0 are within OCG size rules; Hand trap count is 7 and searcher text count is 16; Exact archetype purity is 34.8%
• Inferred: Opening-hand consistency estimates (hypergeometric); Interaction quality read from card text; Ceiling read from card text
• Provisional: Meta Power (null); Matchup and format fit
• Data gaps: no combos supplied, so combo floor, median and ceiling are text-only inference no tournament link, so archetype meta-share and per-pilot record are absent no win-rate telemetry for going-first, going-second, matchups or brick rates Meta Power is Provisional unless a dated metagame sample is supplied deck title is null
