Ayunda Risu

Eminence — At the beginning of each end step,
if Ayunda Risu is on the battlefield or in your
command zone and no spells were cast this turn,
create a 1/1 green Squirrel creature token. You
gain a nut counter.
Risu costs {1} less to cast for each nut counter
you have and each squirrel you control.
Other squirrels you control have forestwalk and
gain +1/+1 for each nut counter you have.
