{w}{r}: Until end of turn, if a source you control would deal damage to a permanent, prevent that damage, and exile that permanent with X time counters, where X is the damage prevented this way. If it doesn't have suspend, it gains suspend.
{3}{w}{r}: Creatures you control get +1/+0 for each card your opponents own in exile and gain first strike until end of turn.
