Simic Containment Unit

Creatures you control enter the battlefield with a
+1/+1 counter.
If you pay {g}{g}{g}{g}{g}{g}{g}{g} or if three or more creatures deal combat damage to you in one turn, create The Hunger, a legendary 0/0 green Ooze creature token with trample and "at the
beginning of your upkeep, triple the number of
+1/+1 counters on this creature.", then sacrifice
