Memento Deck #755503 — Yu-Gi-Oh! OCG

Deck — Deck Power Evaluation

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

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

Legality

Main 58 / Extra 15 / Side 0 — status: Illegal. 4 violation(s).

Identity & game plan

• Win condition: Memento boss pressure from the Extra Deck (Mementoal Tecuhtlica - Combined Creation 5000/5000, Mementotlan-Horned Dragon 2850, Mementomictlan Tecuhtlica - Creation King 3000); inferred from card text and stats, no recorded boards (Inferred); Hand-trap and negation control: Ash Blossom, Infinite Impermanence, Evenly Matched, Nibiru, Droll & Lock Bird (Inferred)
• Turn 1 (going first): Search with Mementotlan Angwitch, Tatsunootoshigo and Bone Party to assemble the Memento engine while holding one hand trap for the opponent's first interaction (Inferred)
• Turn 2 (going second): Open with hand traps and the Memento searchers, then use Raigeki, Mementotlan Feather Duster-style removal and Crossout Designator to clear the board before continuing with Memento Fusion (Inferred)
• Recovery: Recursion from the GY via Mementotlan Ghattic and Mementotlan Akihiron, then Fusion Summon from the Extra Deck (Inferred)
• After siding: No side deck in the export (side_count 0); post-side plan cannot be assessed

Why it scores here

This deck is Illegal: it runs 3 Ash Blossom against a limit of 2, 2 Droll & Lock Bird against a limit of 1, and one copy each of Called by the Grave and Cross-Sheep, which are Forbidden in OCG. Under the rubric it is therefore capped and labelled theoretical/structural-only, and no normal Final Contextual score is given. The structural read is that the Memento engine is coherent: 26 Memento copies, Angwitch, Tatsunootoshigo and Bone Party searchers, and a hand-trap layer that gives it several interruption routes. Consistency is inferred from the hypergeometric estimates, which show a high chance of at least one archetype card in the opening hand, but there are no recorded boards, so the combo floor and median are text-only inference. Popularity did not earn points: archetype usage statistics were used only to see the core composition (14 of 25 core cards present). The score was built from the system (engine access, interaction and closing power), not from averaging individual card scores.

Dimension scores

How the score was computed

Strategy profile: Midrange. Structural ≈ 54.6, Going First ≈ 58, Going Second ≈ 55, Meta = provisional, Tournament Reliability ≈ 52. Modifiers: banlist exposure (-6); no side deck (-2). Final formula: No-meta formula: 0.80*Structural(54.6) + 0.20*TournamentReliability(52) = 54.1; plus context modifiers (-8) = 46.1; capped to 30 because the deck is Illegal (theoretical/structural-only, no normal Final score)

Probability & combo summary

• Opening a starter: P(≥1) ≈ 0.96 · key two-card combo ≈ — · full-brick estimate ≈ 0.04 (all Inferred)
• Combo output: best PowerIndex —, median —, board-per-starter —
• Turn order: 0 going-first lines vs 0 going-second lines

Strengths

• Coherent Memento core: 26 archetype copies with searchers that find the engine on going first
• Layered interaction: 11 hand traps and 12 negation-text cards give several interruption routes
• Boss-heavy Extra Deck with 5000, 3000, 2850 and 2800 ATK threats for closing pressure

Weaknesses

• Illegal list: four copy-limit or Forbidden violations; cannot be played as built
• Low exact-name purity (34.2%) and 21 generic copies dilute the engine
• No side deck, so no post-side plan for best-of-3
• No recorded combos, so floor and median are unmeasured

Critical choke points

• Engine starts from a small set of searchers (Angwitch, Tatsunootoshigo, Bone Party), so a single hand-trap or negate exchange can cut the line
• Forbidden and Limited copies (Called by the Grave, Cross-Sheep, Droll, Ash) must be removed or reduced before the list is playable

Recommended changes

Evidence & confidence

• Verified: Legality: Illegal, 4 violations (Ash 3/2, Droll 2/1, Called by the Grave Forbidden, Cross-Sheep Forbidden); Main 58 and Extra 15 are within OCG size rules; side 0; Archetype purity 34.2%, 26 Memento-related copies; Extra Deck stats for Combined Creation, Horned Dragon, Creation King and Twin Dragon
• Observed: Usage statistics: 14 of 25 archetype core cards present (56%)
• Inferred: Midrange profile and Memento boss pressure as the main plan; Consistency estimates from hypergeometric draw table; Interaction quality from text roles; Going-first and going-second plans
• Provisional: Meta power and matchup fit: no dated meta sample or tournament link
• 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/second, matchup, brick or starter rates Meta power is Provisional without a dated metagame sample Usage statistics conflict with the card list: 14529511 (Mementomictlan Tecuhtlica - Creation King) and 19181420 (Mementotlan Twin Dragon) are in the Extra zone but marked in_this_deck false Deck title is null and no side deck is present
