Indestructible
When A.M. enters the battlefield, each player
chooses a creature they control and exiles the rest.
{4}{t}, Each opponent reveals their hands, choose a nonland card from each and exile it.
You may cast spells exiled by AM and pay any
type of mana for those spells.
"If there was a sweet Jesus and if there was a God,
the God was AM."
— Harlan Ellison, I.H.N.M.I.M.S.
