Ardvald, Spirited by Greed

When Ardvald enters the battlefield, sacrifice it
unless it escaped. Whenever Ardvald enters the
battlefield or attacks, create a treasure token.
Then each opponent loses life equal to the
number of treasure tokens you control.
Escape--{w}{w/u}{u}{u/b}{b}, Exile three other cards
from your graveyard.
Death is a means to an end.
For others, it is a means to a beginning.
