Memento Deck #769905 — Yu-Gi-Oh! OCG

Deck — Deck Power Evaluation

Final Contextual Deck Power: 51/100 (±6 · Confidence: Medium)

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

Legality

Main 44 / Extra 15 / Side 0 — status: Legal.

Identity & game plan

• Win condition: Memento monsters searched by Mementotlan searchers and Fusion/Xyz summons into 2800-3300 ATK boss monsters (Mementomictlan Tecuhtlica - Creation King, Mementotlan-Horned Dragon, K9-X Werewolf, Super Starslayer TY-PHON); Mementoal Tecuhtlica - Combined Creation (5000 ATK, Special Summon by shuffling 5 Memento monsters) as a one-card closer when the Memento graveyard is full
• Turn 1 (going first): Turn 1: Mementotlan searcher (Angwitch / Tatsunootoshigo / Ghattic) into a Memento Special Summon or Fusion, backed by Mementotlan Bone Party or Mementotlan Fusion to start a Fusion Summon
• Turn 2 (going second): Hand trap (Ash Blossom, Infinite Impermanence) on the opponent's opening engine, then rebuild through Memento recursion (Ghattic, Akihiron, Bone Party) and the K9 Xyz line
• Recovery: Recover from the graveyard via Mementotlan Ghattic and Mementotlan Akihiron, reuse Memento Fusion through Mementotlan Fusion, and re-extend with Mementomictlan's search
• After siding: No sideboard is registered, so there is no post-side plan; the deck cannot adapt between games in a best-of-3

Why it scores here

The deck is scored as a system: a 24-card Memento core (about 98.6% chance of at least one core card in the opening 5) and 15 searcher-text cards (about 89% chance of at least one searcher) give it a reliable opening, and the Memento graveyard recursion (Ghattic, Akihiron, Bone Party, Fusion) keeps the plan going after an interruption. Four hand traps and two Ash Blossom copies add real going-second interruption, and the Extra Deck has late-game closers (Creation King 3000 ATK, Horned Dragon 2850, TY-PHON 2900, K9-X Werewolf 3300). The score is pulled down by the absence of any recorded combo boards (text-only inference for D3 and D4), the 37 off-archetype copies that dilute the engine, the zero-card side deck that gives no post-side plan, and the complexity of a three-family Extra Deck. Popularity of the Memento archetype and the archetype-core statistics confirmed that the list is real and accessible, but they earned no points on their own, and no card scores were averaged.

Dimension scores

How the score was computed

Strategy profile: Midrange primary with Toolbox secondary, disclosed; weights taken from the Midrange row of the rubric profile table. Structural ≈ 58.8, Going First ≈ 60, Going Second ≈ 52, Meta = provisional, Tournament Reliability ≈ 52. Modifiers: No sideboard (-3); Engine dilution (-2); Restricted-card exposure (-1). Final formula: 0.80*Structural + 0.20*TournamentReliability + ContextModifiers (Meta provisional) = 0.80*58.8 + 0.20*52 - 6 = 51.4

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

• Dense Memento searcher and recursion package gives a high opening-hand starter rate
• Four hand traps and two Ash Blossoms give real going-second interaction
• Several 2800-3300 ATK Extra Deck closers with complete Extra Deck usage

Weaknesses

• No sideboard, so no post-side adaptation
• Off-archetype dilution across K9, Goblin, Mulcharmy and Umbral Horror lines
• No recorded combo boards, so the floor and median are unobservable

Critical choke points

• Mementotlan searchers and Fusion routes depend on the Memento monsters being live on the field
• Limited-status cards (Harpie's Feather Duster, Reinforcement of the Army, K9-66a Jokul) are one-of and cannot be replaced

Recommended changes

Evidence & confidence

• Verified: Legal status and copy limits for all restricted cards; Main 44 and Extra 15 within OCG size rules; Extra Deck breakdown: 5 Fusion, 8 Xyz, 2 Link; Archetype purity 37.3% exact-name and 37 off-archetype copies
• Inferred: Opening-hand starter rate ~0.986 from the archetype-core group; Searcher access ~0.89 from the searcher-text group; Hand-trap interruption at roughly 0.46 in the going-second 6-card hand
• Provisional: Meta Power (no dated metagame sample); Matchup fit (no tournament link)
• 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 exists in YGOVN Meta Power is provisional without a dated metagame sample no sideboard list, so D12 is a structural read only
