Lauriel, Restorer of Faith

Protection from instant and sorcery spells.
If an instant or sorcery spell targets an angel you control, you may put any number of -1/-1 counters on Lauriel, Restorer of Faith. Counter that spell unless its controller pays {1} for each -1/-1 counter put onto Lauriel. At the beginning of your end step, remove all -1/-1 counters from Lauriel, then put a +1/+1 counter on her.
