Keeping Mementos cause I wanna remember. (Ft. Super Polymerization)

End board usually includes Mementoal Tecuhtlica - Combined Creation and Mementomictlan Tecuhtlica - Creation King with some ways to recur Mementos to use King's effect, plus Mementotlan Cranium Burst to have a negate out, and a Mementotlan Bone Party to destroy Mementotlan-Horned Dragon and trigger removal.

End turn with Mementomictlan to set Burst. Then feel free to destroy it for King.

Also, this build has Super Poly as unavoidable removal, because I wanted this build to use it in some way to stop plays. stuff like Garura, Wings of Resonant Life and Mudragon of the Swamp and Predaplant Dragostapelia can easily use my own cards and others, since memento has a bunch of typings and make it a bit easy to use, and DARK or monsters in archetype have a lot of similarities between them to use. Might not be TOO practical, but i find it fun lol.
