Bix, Purple Urchin

Flying, protection from colorless
{t}: Bix deals damage equal to it's power to target
creature or planeswalker. If a creature or
planeswalker dealt damage this way would die
this turn, exile it instead and draw a card.
At the beginning of your end step, you may
sacrifice a treasure or a gold. If you do, put a
+1/+1 counter on Bix and scry 1.
