I am the Blue Mage is a game by Lilith Briar & Daniel Kong where mages compete to find the most powerful concept in the universe. Think "the little stone miner who wanted to be the sun, then the cloud, etc. then the mountain, and back to stone miner. (conservative mythology or clever kid's tale?)
I am the Witch is a hack of this game, only less abstract, more in the flesh. You RP the whole reunion of witches gossiping and wishing and competing for the Crown.
The heart of the game is formal duels, which you can paint as the Madame Mim vs Merlin anthology scene, Sun Wu Kong encounters or Magic:The Gathering if that's your fancy.
And that's it.
