Memento Deck #772787 — Yu-Gi-Oh! OCG

Deck — Deck Power Evaluation

Final Contextual Deck Power: 38/100 (±8 · Confidence: Low)

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

Legality

Main 52 / Extra 18 / Side 0 — status under the rules at evaluation time: Illegal. 3 violation(s).

Identity & game plan

• Win condition: Memento board pressure: Mementoal Tecuhtlica - Combined Creation (5000 ATK) and the Fusion/Link end-boards (Mementomictlan Tecuhtlica - Creation King 3000, Mementotlan Twin Dragon 2800, Mementotlan-Horned Dragon 2850) once the Memento GY loop is online.; Fusion-based boards via Mementotlan Fusion and Super Polymerization, backed by Link and Fusion extra-deck attackers.
• Turn 1 (going first): Open on Memento starters (Angwitch, Tatsunootoshigo, Shleepy, Ghattic) that search or Special Summon the next Memento piece, then convert into a Fusion or Link summon through Mementotlan Fusion; hold Ash Blossom and Infinite Impermanence for the opponent's first interaction. Going-first openers are inferred from card text only, since no combo boards exist.
• Turn 2 (going second): Use Ash Blossom, Droll & Lock Bird, Nibiru and Infinite Impermanence to slow the opponent's first summon chain, then rebuild through Memento GY recursion (Ghattic, Akihiron, Horned Dragon). Going-second strength is inferred and unverified.
• Recovery: Recursion through Mementotlan Bone Party, Ghattic, Akihiron and the GY-based Horned Dragon summon, plus Mementotlan Mace control steal on a Tecuhtlica-protected board.
• After siding: No side deck is registered, so there is no post-side plan. Best-of-3 play would depend on re-building the list from scratch.

Why it scores here

The Memento core is in the deck at 32 copies, and the hypergeometric estimate of at least one archetype-core card in an opening hand of five is about 0.99, so the engine comes online often (Inferred). Ten hand traps, ten negation-text cards and 28 removal-text cards give the list real interaction density, which earns the end-board and resilience dimensions, though this is a semantic read of card text rather than measured combo data (Inferred). The deck's real weakness is composition: only 34 percent of copies are exact-name Memento and 46 copies are off-archetype, so the list runs many generic tech cards (Raigeki, Metaltronus, Nibiru, Infinite Impermanence), which lowers consistency and efficiency. The score does not reflect the archetype's popularity, which only confirms it is a real list, and it is not an average of the individual card scores. The Illegal status (Extra Deck 18 against a limit of 15, plus three copies each of two Semi-Limited cards) caps the final score and makes this a structural read only.

Dimension scores

How the score was computed

Strategy profile: Combo. Structural ≈ 52, Going First ≈ 45, Going Second ≈ 42, Meta = provisional, Tournament Reliability ≈ 40. Modifiers: banlist_copy_violation (-6); extra_deck_size_illegal (-4); no_side_deck (-2). Final formula: 0.80*Structural + 0.20*TournamentReliability + ContextModifiers (Meta provisional); Structural 52.3, TR 40, modifiers -12 → 37.8 ≈ 38 (Illegal: theoretical/structural read only)

Probability & combo summary

• Opening a starter: P(≥1) ≈ 0.99 · 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

• Archetype core present in about 99 percent of opening hands
• Dense interaction across hand traps, negation text and removal text
• GY recursion and Fusion or Link extra-deck end-boards with high ATK

Weaknesses

• Illegal as built: Extra Deck over 15, and two Semi-Limited cards at 3 copies
• Low archetype purity (34 percent exact name), with generic tech cards diluting the line
• No side deck and no recorded boards

Critical choke points

• Single-card dependence on Mementotlan Fusion and Super Polymerization for Fusion access (text-based inference)
• Hand-trap hand-of-6 coverage is only about 74 percent going second (Inferred)

Recommended changes

Evidence & confidence

• Verified: Legality: Extra Deck 18 exceeds the OCG limit of 15; Legality: Ash Blossom and Super Polymerization each run 3 copies against a Semi-Limited limit of 2; Archetype purity: 24 exact-name copies, 46 off-archetype, 34.3 percent; No side deck registered; no tournament link; no combos recorded
• Inferred: Core engine accessibility from hypergeometric estimate (0.994); Interaction density from hand-trap and negation text counts; Combo ceiling and floor are text-only estimates; Going-first and going-second plan read from card text
• Provisional: Meta power and matchup fit: no dated metagame sample; Tournament reliability
• 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 match record are absent No win-rate telemetry for going-first, going-second, matchup or brick rate Meta power is provisional without a dated metagame sample No side deck registered, so post-side performance cannot be assessed
