Sanngriðr, Traitor to Odin

Flying, Indestructible, Deathtouch
Whenever a creature dies, you may pay
{1}{b}{r}. If you do, exile that creature and put X +1/+1 counters on Sanngridr, Traitor to Odin, where X is that creature's converted mana cost.
"To deny ascendance to the sons and daughters
of Odin is the greatest of blasphemies." - Sigrdrifa
