Gandalf of the Secret Fire

Whenever you cast an instant or sorcery spell
from your hand during an opponent's turn,
exile that card with three time counters on it instead
of putting it into your graveyard as it resolves.
Then if the exiled card doesn't have suspend,
it gains suspend.
"So do all who live to see such times. But that is
not for them to decide. All we have to decide is what
to do with the time that is given us."
