Has to have tag team mode. Needs spellcards, but instead of the official fighting game styles, you gain access to spellcards by collecting point items that appear when anyone is hit. When you have enough, you can use your character's weakest spellcard. After that, you use the second weakest, so on and so forth. When you use your Last Word, if your opponent isn't KO'd, you lose.

Also, spellcards would be closer in spirit to Marisa's "Orreries Sun" or Alice's "Futuristic Hourai" - They completely change your mode of attack for a set time or until you take enough damage.

Aside from the change of cards, IaMP, but with a full roster.
