Ooze Titan

Sacrifice an Ooze: Put a +1/+1 counter on target
Ooze creature you control.
Suspend 7—{1}{b}{g} (Rather than cast this card
from your hand, you may pay {1}{b}{g} and exile it
with seven time counters on it. At the beginning of
your upkeep, remove a time counter. When the last is removed, cast it without paying its mana cost. It has
haste.)
Whenever a time counter is removed from Ooze
Titan while it's exiled, create a 1/1 green Ooze creature token.
