Muglar Corpse Catcher

Whenever a non-token creature an opponent
control dies, that creature's controller may pay
toll 1. (That opponent may have you create a
Treasure token.) If he doesn't, exile that creature
and put a +1/+1 counter on Muglar
Corpsecatcher.
Muglar's Clan will return the body of a fallen enemy,
for an hefty sum. It is best to forget what happens
when the price isn't payed.
