Weamou, Lord of Turbulence

Flying, Prowess
Whenever you cast an instant or sorcery spell, creatures besides Weamou, Lord of Turbulence
get -1/-2 until end of turn.
At the beginning of each upkeep, roll a six-sided
die. Exile that many cards from the top of your
library. Until the beginning of your next turn,
you may cast instants and sorceries from among
them as though they had flash.
