OK, this is it. I walk up to the gates of Azkaban prison, counting up mana costs. The dementors swirl. I know I should cast a patronus, but I cast a fireball. And then read the Dementor's mind, then destroy it. Ducking inside, I run towards Icy. Wait, where am I? Using my divine magic, I sense her presence. Running towards the tourture chamber, I cast a beam of brilliant white light. The dementors stand back and I throw open the door. Summoning a dense cloud of goblins, I tell them to find Icy. The dementors and I wage war as the goblins spread out. Finally, I summon another planeswalker. I tell the planeswalker, named Narset, to go find Icy. Icy, please don't be an idiot. The planesw-- wait, what is that? A manifestation of pure Black Mana. I summon a shield, but it fails. I run back. Why are they keeping this alive? Izzet Weirds, go into that room and blow some stuff up!
