Kaoz, Lord Of Fracture

Whenever Kaoz, Lord Of Fracture leaves the battlefield flip a coin. You lose the game if you
chose right, and win the game if you chose wrong.
Whenever this creature becomes the target of a
spell or permanent a player controls, exile that
spell or permanent from the stack or battlefield.
Its controller exiles the top of their library until
they reveal a spell or a permanent that shares a
type and cast it without paying its cost. Shuffle
the rest into the library.
