I actually use her as one of the 99 in my Calamity, Galloping Inferno deck. Mostly using her as a way to pitch late game lands into usable creatures and also drawing a card off of them.
So an example of play with her would be to pay a red and pitch a card I don't need, create a copy of something like Zealous Conscripts to untap her, repeat as needed to remove dead draws, and eventually take away a blocker with the last copy or target a fatty. After that move to combat and draw a card for each copy that was created when it dies at end of turn. If I have a sac outlet like Ashnod's Altar or the like then you could even sacrifice the tokens on main phase 2 for both the card draw and mana. Alternatively Sundial of the Infinite on end phase keeps the draw trigger on the token while avoiding the sacrifice delayed trigger.
