Basat Squad

On your end step, attach a randomly chosen
Mark of Chaos to this creature. (It is a token
Aura that gives one of the following effects:
+2/+0 ; +1/+0 and First Strike ; +1/+1 and
Flying ; +0/+2 and Toxic 1. If two of the same
Mark of Chaos are attached to a creature,
sacrifice one of them. When a creature gains
all 4 unique Marks, exile this creature and put
a randomly chosen Greater Daemon token
onto the battlefield under your control.)
