An ability that triggers when you cast a spell resolves before the spell that caused it to trigger. It resolves even if that spell is countered.

This ability doesn’t trigger if you copy a spell that targets it, or if a spell’s targets are changed to target it.

If you cast a spell that targets this creature multiple times, this ability triggers just once.

This effect affects only creatures you control at the time the ability resolves. Creatures you begin to control later in the turn won’t get +1/+0.
