Blob, Experimental Goo

Deathtouch
At the beginning of your upkeep, create a 1/1
green Ooze creature token. Then put a number
of +1/+1 counters on Blob, Experimental Goo
equal to the number of other Oozes you control.
Ooze creatures you control have undying. (When
a creature with undying dies, if it had no +1/+1
counters on it, return it to the battlefield under its
owner's control with a +1/+1 counter on it.)
