Flourishing Seal

Sacrifice Flourishing Seal: Remove each counter
from each player and permanent.

Cumulative upkeep—Deal put a +1/+1 counter on
target creature. (At the beginning of your upkeep, if
this permanent is on the battlefield, put an age
counter on this permanent. Then you may put a
+1/+1 counter on target creature for each age counter
on it. If you don’t, sacrifice it.)
