Memento Deck #773052 — Yu-Gi-Oh! OCG

Deck — Deck Power Evaluation

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

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

Legality

Main 55 / Extra 14 / Side 0 — status under the rules at evaluation time: Illegal. 2 violation(s).

Identity & game plan

• Win condition: Memento Fusion/Link boards (Mementotlan Twin Dragon, Mementomictlan Tecuhtlica - Creation King, Mementotlan-Horned Dragon, Mementoal Tecuhtlica - Combined Creation) built through Memento Special Summon chains and Fusion Spells; Mementotlan Fusion and Super Polymerization conversion into Extra Deck bosses; hand-trap-protected turns
• Turn 1 (going first): Open on an archetype starter (Mementotlan Angwitch, Mementotlan Tatsunootoshigo, Mementotlan Dark Blade) that searches or summons a second Memento, then convert through Mementotlan Fusion into a Fusion boss; Ash Blossom and Ghost Ogre hold up one negation or removal
• Turn 2 (going second): Use the 7 hand traps (Ash Blossom, Ghost Ogre & Snow Rabbit, Droll & Lock Bird) and Forbidden Droplet to answer the opponent's first board, then rebuild through Memento graveyard recursion (Mementotlan Ghattic, Mementotlan Goblin)
• Recovery: Recover from the GY with Mementotlan Bone Party, Mementotlan Ghattic, and Mementotlan Akihiron recursion; Mementomictlan Tecuhtlica - Creation King banished from GY adds Mementomictlan back
• After siding: Not evaluable: the list has no side deck, so there is no post-side plan

Why it scores here

The deck reliably opens an archetype starter (about 99% chance of at least one Memento-core card in a 5-card opening hand, Inferred), and its 18 searcher-text cards and recursion lines keep the engine live through the first two turns. Interaction is the strongest part of the system: 7 hand traps, 6 negation-text cards and 27 removal-text cards give it a real answer to a first board. Conversion into a Fusion or Link boss is plausible but unverified, because no recorded boards exist and the best-line ceiling and median output cannot be measured. Popularity did not earn points: the Memento archetype is well represented in usage statistics, but that only confirms the list is real, and the deck was scored as a connected system rather than by averaging card scores. The 2-copy overflow of Ash Blossom and Super Polymerization makes the list illegal, so the score is capped and reported as structural only.

Dimension scores

How the score was computed

Strategy profile: Midrange primary, Toolbox as secondary (hand-trap and tech density), disclosed; structural weights used unchanged. Structural ≈ 56, Going First ≈ 54, Going Second ≈ 57, Meta = provisional, Tournament Reliability ≈ 42. Modifiers: banlist and copy-limit exposure (-8); no side deck (-4). Final formula: No reliable metagame: 0.80*Structural + 0.20*TournamentReliability + modifiers = 0.80*56 + 0.20*42 - 12 ≈ 41, then the Step 2 illegal cap applies and the score is set to 35. Theoretical/structural-only result.

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

• Near-certain archetype starter access in the opening hand
• Dense interaction: hand traps, negation text and removal text
• Recursion lines (Ghattic, Bone Party, Akihiron) for resilience and rebuilds
• Strong Extra Deck boss ceiling in Creation King, Horned Dragon and Twin Dragon

Weaknesses

• Illegal list: Ash Blossom and Super Polymerization are over the OCG copy limit
• No side deck, so no best-of-3 adaptation
• Low main-deck compactness with 16 tech slots and 34.8% exact archetype purity
• No recorded combos, so the real conversion rate is unknown

Critical choke points

• Archetype starters that all require Memento monsters already on the field or in hand
• Fusion conversion depends on Mementotlan Fusion and a live Memento Extra Deck boss
• Single-copy Extra Deck bosses have only about 0.25 access per copy in a 5-card hand

Recommended changes

Evidence & confidence

• Verified: Main Deck 55 cards and Extra Deck 14 cards are within OCG size rules; Ash Blossom and Super Polymerization are each run 3 times against a legal limit of 2; Five Limited cards are run at exactly 1 copy each; Archetype exact-name purity is 34.8%
• Inferred: Starter access ≈ 0.99 for the Memento core; Interaction density from hand-trap and negation text; Recursion gives a second line after one disruption
• Provisional: Median and floor output (no recorded boards); Matchup and format fit (no meta sample)
• Data gaps: No recorded combos, so ceiling, median and floor are text-only inference No tournament link, so archetype meta-share and pilot record are absent No win-rate telemetry exists in YGOVN No side deck, so post-side plan cannot be evaluated Meta Power is Provisional without a dated metagame sample Deck has no title
