Memento Deck #773055 — Yu-Gi-Oh! OCG

Deck — Deck Power Evaluation

Final Contextual Deck Power: 35/100 (±10 · Confidence: Low)

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

Legality

Main 40 / Extra 15 / Side 0 — status under the rules at evaluation time: Illegal. 1 violation(s).

Identity & game plan

• Win condition: Fusion-summon Memento boss monsters (Mementomictlan Tecuhtlica - Creation King 3000 ATK, Mementotlan Twin Dragon 2800 ATK, Mementoal Tecuhtlica - Combined Creation 5000 ATK) from a field of Memento monsters, then convert the board with the boss attack.; Recurring Memento bodies from the GY through Mementotlan Bone Party, Ghattic and Akihiron to keep the Fusion engine going over several turns.
• Turn 1 (going first): Open with Memento searchers (Angwitch, Tatsunootoshigo, Ghattic) and a Fusion spell (Mementotlan Fusion or Super Polymerization) to summon a Creation King or Twin Dragon by turn 2. Inferred from card text, no combo data.
• Turn 2 (going second): Use Mulcharmy Fuwalos or Purulia to draw off the opponent's summons and rebuild the hand, then reach the same Memento Fusion boss. Inferred from card text.
• Recovery: Recur Memento monsters from the GY with Bone Party, Ghattic or Akihiron, and reuse the Creation King GY banish-to-search to find Mementomictlan again.
• After siding: No side deck is registered (0 side cards), so there is no post-side plan. Any sideboard change is currently undefined.

Why it scores here

The deck reliably opens a Memento searcher or Fusion spell on turn 1 in most hands: 22 exact-name Memento copies with one of the 16 searcher-text cards gives about a 0.94 chance of at least one searcher in a 5-card opening hand (Inferred from hypergeometric draws). Its ceiling comes from the Memento Fusion bosses, and recursion through the graveyard keeps the engine running after one interruption. Scores are not based on the archetype's popularity; usage statistics confirm the core is real but do not add points. The score comes from consistency, a recursion-based engine, and removal-heavy interaction on the whole system, not from averaging card scores. Off-archetype dilution (Sky Striker, Mulcharmy, Goblin), no combo records, no hand traps and an empty side deck cap the score. The deck is illegal as built (3 copies of Super Polymerization against a limit of 2), so the final score is capped and the evaluation is theoretical and structural only.

Dimension scores

How the score was computed

Strategy profile: Midrange primary, no secondary blend applied. Structural ≈ 55, Going First ≈ 60, Going Second ≈ 48, Meta = provisional, Tournament Reliability ≈ 50. Modifiers: Banlist exposure (-4); Engine conflicts (-2); Illegal deck cap (-13). Final formula: No reliable metagame: 0.80*Structural(55) + 0.20*TournamentReliability(50) = 54; modifiers -6 gives 48; illegal-deck cap applied, final 35 (theoretical/structural only)

Probability & combo summary

• Opening a starter: P(≥1) ≈ 0.94 · 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

• Dense searcher and recursion text across the Memento core
• Three 3-of starters plus a 3-of Fusion spell give strong opening access
• Boss Fusion Monsters with high ATK and multiple closing lines
• Compact main deck of 40 with a full 15-card Extra Deck

Weaknesses

• Illegal as built: Super Polymerization over the OCG copy limit
• No hand traps, no floodgates, and no side deck
• Off-archetype splash (Sky Striker, Mulcharmy, Goblin) dilutes the engine
• No combo or tournament evidence to confirm median output

Critical choke points

• Super Polymerization is the only Fusion spell that can go through the field; with one copy cut to two, Mementotlan Fusion and Bone Party must carry the Fusion route
• Creation King needs 3 Memento monsters on board or in the GY, so an early removal can stop the boss line

Recommended changes

Evidence & confidence

• Verified: Legality: Super Polymerization 3 copies vs legal 2 (OCG Semi-Limited); Main 40 / Extra 15 / Side 0 match OCG size rules; Copy histogram 1x10 / 2x3 / 3x8; Archetype purity: 22 exact Memento copies, 40 percent; Extra Deck breakdown 9 Fusion, 5 Link, 1 Synchro
• Observed: Usage statistics: core cards present at 60 percent of the archetype's stat rows
• Inferred: Starter access about 0.94 from searcher text (hypergeometric); Boss lines and closing power from card text; Going-first and going-second estimates; Floor and median estimates (no recorded boards)
• Provisional: Meta Power (null, no dated metagame sample); Format fit and matchup coverage (no tournament data)
• 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 for this deck Meta Power provisional unless a dated metagame sample is supplied Deck title is null in the export
