At the beginning of each end step, create a
1/1 green Saproling creature token for each
life you lost or gained this turn.
Rot {2}{g}{b} (You may cast this spell for its rot
cost. If you do, put X time counters on it where
X is the number of creatures in your graveyard.
At the beginning of your upkeep, remove a time counter from it. When the last is removed, sacrifice it.)
