Memento Deck #768249 — Yu-Gi-Oh! OCG

Deck — Deck Power Evaluation

Final Contextual Deck Power: 25/100 (±8 · Confidence: Low)

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

Legality

Main 55 / Extra 15 / Side 0 — status: Illegal. 3 violation(s).

Identity & game plan

• Win condition: Memento Extra Deck boss monsters (Mementoal Tecuhtlica - Combined Creation at 5000 ATK, Mementomictlan Tecuhtlica - Creation King at 3000 ATK, Mementotlan-Horned Dragon at 2850 ATK) reached through Memento recursion and Fusion; Link beatdown and disruption-backed attacks through Underworld Goddess, A Bao A Qu and W:P Fancy Ball
• Turn 1 (going first): Open with a Memento starter (Angwitch, Tatsunootoshigo, Shleepy or Bone Party), search or summon another Memento, and build toward a Fusion or Special Summon of a boss while holding Solemn and hand-trap backup
• Turn 2 (going second): Use hand traps (Evenly Matched, Ghost Ogre and Snow Rabbit, Droll and Lock Bird) and Solemn effects to break the opponent's first summon, then recover through Memento GY recursion
• Recovery: Rebuild from the GY using Mementotlan Goblin, Ghattic and Akihiron to add or revive Memento monsters, and use Mementomictlan to Special Summon lower-level Memento monsters
• After siding: No side deck is registered, so no post-side plan can be evaluated; the deck must be legalized and given a side before it is judged for best-of-3 play

Why it scores here

The deck is scored as a system: its Memento core (33 copies, with a 0.99 estimated chance of at least one core card in a 5-card opening hand) gives it a reliable starter, and its Memento recursion and Fusion boss package give a credible ceiling of 3000 to 5000 ATK bosses. Interaction is the deck's strongest area, with 7 hand traps, Solemn Judgment and Solemn Warning, and 3 Typhoons, which lift interaction quality to 70 on an inferred basis. Consistency and floor are held back by a split engine: only 26 of 55 main cards carry the exact Memento name, and 44 are off-archetype, spread across Mulcharmy, Goblin, Branded, Solemn, Radiant Typhoon and Predaplant. Popularity or archetype usage stats were not used to raise any score, and card scores were not averaged. The list is Illegal (Geonator Transverser is Forbidden, and The Fallen and The Virtuous exceeds its Semi-Limited limit), so the structural score of 55 is capped to a low final score of 25, and the evaluation is theoretical only.

Dimension scores

How the score was computed

Strategy profile: Midrange. Structural ≈ 55, Going First ≈ 58, Going Second ≈ 52, Meta = provisional, Tournament Reliability ≈ 45. Modifiers: banlist exposure (-12); illegal-list cap (-16). Final formula: 0.80*Structural + 0.20*TournamentReliability (Meta provisional) = 53, then a -12 banlist modifier gives 41, then the Illegal cap sets the final score to 25 (theoretical only)

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 core with a near-certain starter in the opening hand
• Layered interaction with 7 hand traps, 2 Solemn cards, and 3 Typhoons
• Strong GY recursion and boss ceiling of 2800 to 5000 ATK

Weaknesses

• Illegal list: Forbidden Geonator Transverser and a 3-copy Semi-Limited Fallen and Virtuous
• Split engine with only 37 percent exact-name purity and 11 sub-archetypes
• No side deck, so there is no best-of-3 plan

Critical choke points

• Legality fix to the Extra Deck: the Forbidden Geonator Transverser slot must be replaced before the deck is playable
• Most of the engine depends on Memento monsters staying on the field or in the GY, so one board wipe or hand-trap line can end the turn
• Going second depends on hand traps being in hand, and P(at least one hand trap in a 6-card hand) is 0.58

Recommended changes

Evidence & confidence

• Verified: Legality: Illegal, 55 main, 15 extra, 0 side; Geonator Transverser is Forbidden and run at 1 copy; The Fallen and The Virtuous is Semi-Limited with a 2-copy limit and is run at 3; Droll and Lock Bird, S:P Little Knight and Solemn Judgment are Limited and each run at 1; 33 core Memento copies; archetype core usage 100 percent on the core list; Card text for hand-trap, negation and removal roles from the deck evidence
• Observed: Usage statistics show Memento core cards at 100 percent inclusion across 11 lists
• Inferred: P(at least one core card in hand of 5) 0.99; P(at least one 3-copy starter in hand of 5) 0.25; P(at least one hand trap in hand of 6, going second) 0.58; Interaction quality 70 from card text layering; Structural score 55 from the Midrange weight profile
• Provisional: Meta Power is null because no dated metagame sample exists; Matchup fit (D13) scored 45 without tournament or meta data
• Data gaps: No combos supplied: combo floor, median, and ceiling are text-only inference No tournament link: archetype meta-share and per-pilot match record are absent No win-rate telemetry for going-first, going-second, matchups, or brick rates Meta Power is provisional without a dated metagame sample No side deck was supplied, so post-side scoring is unavailable No guides attached to this deck (0 guides)
