Isaac, Eye of the Storm

Channel Divinity - Isaac enters the battlefield
with a divinity counter on him.
Fireball - {2}{r}, {t}: Isaac deals 3 damage divided
as you choose between any number of targets.
Destructive Wrath - {2}{u}{r}, remove a divinity
counter from Isaac: the next time a red source
of your choice would deal damage this turn, it
deals triple that damage instead.
