It That Swallowed the Town

Whenever a nontoken creature you control dies,
create a 1/1 green Ooze creature token.
At the beginning of your end step, put a +1/+1 counter on each other ooze you control without a
+1/+1 counter on it. Then, if you control ooze creatures with a total power of 25 or greater,
remove all +1/+1 counters from creatures you
control. Destroy target nonland permanents you
don't control equal to the number of counters
removed this way.
