There's actually a male Miqo'te who participates rather regularly at the Runestone who refers to his style as "Hat Magic." He literally has a big top hat and it is where all his spells and such emanate from. Name is... Zero Dawnstar or something? His name escapes me but if you ask around there, you'll find a way to him I think.
He's had fire bunnies come bursting out of it, "caught" a spell in the hat and sent it back, and other such tricks. He very much plays his matches as a theatrical performance, bringing out all sorts of glamor and flair that I think might fit what you're looking for. Or, at least, serve as a bit of an inspirational springboard to work off of.
But yeah, I think you'd be just fine with exploding cards and other such tricks tweaked for more combat relevance.
