Memento Deck #772309 — Yu-Gi-Oh! OCG

Deck — Deck Power Evaluation

Final Contextual Deck Power: 53/100 (±6 · Confidence: Medium)

• Primary strategy: Midrange
• Secondary strategies: Toolbox, FTK/Alternate-Win
• Format: ocg

Legality

Main 43 / Extra 15 / Side 0 — status: Legal.

Identity & game plan

• Win condition: Fusion and Xyz pressure from Memento monsters (Mementoal Tecuhtlica - Combined Creation at 5000 ATK, Mementomictlan Tecuhtlica - Creation King at 3000 ATK) with recursion-based searchers.; K9 Xyz and Link pressure, plus Goblin Xyz support, as a second route when Memento pieces are absent.
• Turn 1 (going first): Open on a Memento searcher or summon (Angwitch, Dark Blade, Tatsunootoshigo, Ghattic) and extend into Fusion or Xyz pressure, using the Memento-core redundancy (25 core copies, about 99% to open at least one in a 5-card hand) to keep the engine live.
• Turn 2 (going second): Six-card hand with Ash Blossom x2, Infinite Impermanence x2 and Harpie's Feather Duster for interaction, then rebuild the Memento board through GY recursion and searchers.
• Recovery: Recover through GY-to-hand searchers and GY-banish recursion (Creation King, Ghattic, Akihiron), plus Mementomictlan to re-establish the Memento engine after a broken board.
• After siding: No side deck is registered, so there is no post-side plan in the evidence; post-side adaptation is unscored and recorded as a gap.

Why it scores here

The deck reliably opens its Memento core: the archetype core group has about a 99% chance of at least one copy in a 5-card opening hand, and 15 searcher-text cards give about 90% access to a searcher by the same measure. Conversion comes from the Fusion and Xyz top end (Combined Creation at 5000 ATK, Creation King at 3000 ATK), but no recorded boards exist, so the ceiling is text-inferred. Interaction is the strongest part of the system, with four hand traps, two Infinite Impermanence, Harpie's Feather Duster and Forbidden Droplet providing layered answers, and about 46% odds of a hand trap in a 6-card going-second hand. Scoring is on the system, not on averaged card scores, and popularity earned no points: the usage stats only confirm the core list is standard for the archetype. The side deck is empty and there is no meta sample, so post-side adaptation and matchup fit are capped at low confidence.

Dimension scores

How the score was computed

Strategy profile: Balanced (no combo evidence to break a strategy tie). Structural ≈ 60, Going First ≈ 54, Going Second ≈ 58, Meta = provisional, Tournament Reliability ≈ 50. Modifiers: Side deck empty (-3); Dependence on one Extra-Deck card (-1); Engine conflicts across sub-archetypes (-2); Banlist exposure (-1). Final formula: 0.80*Structural + 0.20*TournamentReliability + ContextModifiers (Meta provisional; D13 dropped and weights renormalised for a meta-neutral structural score): 0.80*59.7 + 0.20*50 - 5 = 52.8, rounded to 53

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

• Core Memento access is very high (about 99% for at least one core-line card in a 5-card hand).
• Layered interaction: 4 hand traps, Ash Blossom x2, Infinite Impermanence x2, Harpie's Feather Duster, Forbidden Droplet x2.
• Strong top end with 5000 ATK Combined Creation and 3000 ATK Creation King.
• Legal list with all copy limits respected.

Weaknesses

• No side deck, so post-side adaptation is absent.
• Exact archetype purity is only 38%; K9, Goblin and Harpie splash competes for slots with the Memento engine.
• High pilot complexity across Fusion, Xyz and recursion lines.
• No recorded boards, so the combo ceiling and median are unmeasured.

Critical choke points

• Creation King x2 (Extra Deck) gates much of the top-end conversion.
• The Memento monster line (Dark Blade, Angwitch, Tatsunootoshigo) is needed to start most engines; hand-trap interruption at the first summon is a single point of failure.

Recommended changes

Evidence & confidence

• Verified: Legality: Legal, 43 main / 15 extra / 0 side within OCG size rules; no copy-limit violations.; Banlist status of restricted cards (Limited/Semi-Limited) at legal copies.; Card stats and text excerpts for all listed cards.; Archetype core group (25 copies) and usage stats: 15 of 25 core cards present.
• Observed: Usage-stat inclusion for core Memento cards (100% for Combined Creation, Angwitch, Tatsunootoshigo).
• Inferred: Hypergeometric opening-hand consistency (about 0.99 core, 0.90 searcher, 0.46 hand trap at going-second).; Interaction quality from text and hand-trap counts.; Ceiling and recursion read from card text, not from boards.; Going-first and going-second power estimates.
• Provisional: Meta Power and D13 matchup fit (no dated meta sample; archetype share unavailable).; Tournament reliability weighting (no per-pilot match record).
• Data gaps: No combos supplied: combo floor, median and ceiling are text-only inference. No tournament link: archetype meta-share and per-pilot record absent. No win-rate telemetry (going-first/second, matchup, brick, starter rates). Side deck empty: post-side plan cannot be evaluated. Meta Power is Provisional unless a dated metagame sample is supplied.
