Leppo, Virile Sire

Cumulative upkeep—Sacrifice a nontoken
permanent
When Leppo, Virile Sire enters the battlefield,
create two 1/1 white Rabbit creature tokens.
Whenever Leppo's cumulative upkeep is paid,
for each creature token you control with base
power and toughness 1/1, create X tokens that
are copies of that creature, where X is the
number of age counters on Leppo.
