Azura's Star

Whenever a card is put into a graveyard from
anywhere, exile it instead.
Whenever a card is exiled, if there are 10 or
more cards exiled with Azura's Star, you may
pay {1}. If you do, put a +1/+1 counter on target
creature and you gain 2 life.
"Azura's prophecies always come to pass. To deny
them is to go headlong into the darkness with no
light to guide you." ~ Aranea Ienith
