During the Main Phase: Fusion Summon 1 Fusion Monster from your Extra Deck, using monsters from your hand or field as material, including a "Memento" monster. If a monster(s) in your possession was destroyed by card effect this turn, you can also shuffle "Memento" monsters from your GY into the Deck as material. During your Main Phase: You can banish this card from your GY; destroy 1 monster you control, and if you do, add 1 "Memento" Spell/Trap from your Deck to your hand. You can only use each effect of "Mementotlan Fusion" once per turn.

Why it scores here
Mementotlan Fusion is a Quick-Play Spell whose main-phase Fusion Summon turns hand and field Memento monsters into a Fusion boss; the 99% partner rate with Mementoal Tecuhtlica - Combined Creation confirms that conversion is the card's job. Its GY effect (banish, destroy 1 of your monsters, add a Memento Spell/Trap from Deck) is a real but costly search that nets roughly zero card advantage in the sampled boards. The card has no ATK, DEF or opponent interaction, so its 400/400 deck presence and 45-archetype spread earn accessibility and deck-cost credit only, not power for its own sake.
Axis scores
| Axis | Score | Evidence |
|---|---|---|
| Accessibility | 72 | Present in all 400 sampled decks at about 2.84 copies each and reachable through Memento hand/field routes; the Deck-side Memento Spell/Trap search is inferred from text, not from a recorded starter or searched count (inferred). |
| Combo & Conversion | 55 | Fusion Summon into a Fusion boss from hand/field materials is verified by text, and the Tecuhtlica partner at 99% supports it, but sampled boards average power index 34.9 with no boss or end-board pieces (observed). |
| Resource Economy | 45 | The GY banish-and-search costs one of your own monsters to add one Memento S/T, and the sampled boards show netCardAdvantage 0 (verified text, observed). |
| Effect & Interaction | 5 | The card has no negation, removal or hand-trap reach; its only destroy hits a monster you control (verified). |
| Material Utility | 5 | A Spell is never Material itself, so this axis is near zero by definition (verified). |
| Resilience & Flexibility | 50 | The Fusion effect is a Main Phase Spell that can be negated, while the GY effect can be used from the graveyard after it is discarded or sent there, giving some multi-zone reach (verified text, inferred). |
| Deck-Building Efficiency | 55 | It is a single-copy-friendly staple with no banlist token and an assumed 3-copy limit, but guides say the Memento plan requires extra brick-like cards, which lowers the score (observed, guide snippet). |
Calculation
Weight profile: 0.7 Starter + 0.3 Searcher. Intrinsic ≈ 49, Deck ≈ 58, Meta = provisional. Modifiers: Memento-only target restriction (-2). Final formula: 0.40*Intrinsic + 0.60*Deck
Strengths
- Converts a hand or field of Memento monsters into a Fusion boss in one main-phase action
- Searches a Memento Spell/Trap from Deck through the GY effect
- Present in every sampled Memento deck at near-maximum copies
- Partners with 11+ Memento staples at 99% co-occurrence
Weaknesses
- No ATK, DEF or opponent interaction of its own
- The GY search destroys one of your monsters, so it does not gain card advantage
- Each effect is once per turn, which limits repeat use
- Power is tied to Memento board requirements and does not travel to other archetypes
Counters / choke points
- Spell negation on the Fusion activation
- Board disruption that removes Memento monsters before the Main Phase
- Interruptions to the Memento monster set needed for Fusion material

Evidence & gaps
- Verified: Main Phase Fusion Summon of 1 Fusion Monster from Extra Deck using hand or field materials, including a Memento monster; GY effect: banish this card, destroy 1 monster you control, add 1 Memento Spell/Trap from Deck; Each effect is once per turn; Present in 400/400 sampled decks, avg 2.84 copies; Mementoal Tecuhtlica - Combined Creation co-occurs in 99% of decks
- Observed: 7 of 7 combos include the card, but combo role is empty for all examples; Sampled combo power index average 34.9, with examples at 48, 46 and 32; netCardAdvantage 0 in the sampled boards; Memento archetype inclusion at 83–100% in usage statistics
- Inferred: The Fusion effect converts hand and field Memento monsters into a boss; The GY effect is a costly search that is roughly card-neutral; Power is tied to Memento board requirements and does not travel to other decks
- Data gaps: no banlist token — assumed 3 copies (unlimited) combo combo role tags are empty, so starter, searched and material splits are all 0 and cannot be verified no combo examples show a boss or end-board outcome, so conversion is inferred from card text no dated meta sample; meta power is null
