Chosen Undead

Darksign (Whenever this card is put into the
graveyard from anywhere, if you have 3 or more
hollow counters, exile it. Otherwise, you
get a hollow counter.)
{p/w}: Return Chosen Undead from your graveyard
to the battlefield tapped.
Whenever a creature you don't control is sent to
the graveyard, place a +1/+1 counter on
Chosen Undead.
