{x}, {t}: Look at the top card of X target
opponent's libraries. You may exile a non-land
card revealed this way with three time counters
on it. If it doesn't have suspend, it gains suspend.
When you cast an instant or sorcery spell from
exile, copy it. You may choose new targets for
the copy.
When you cast a permanent spell from exile,
create a token that is a copy of it.
