Kharis & the Beholder

Flying
When Kharis and the Beholder enters the battlefield and at the beginning of your upkeep,
create a 1/1 white Human creature token and roll
a d20.
• If the result plus the number of creatures you control is greater than 11, put a +1/+1 counter
on each creature you control.
• If the result is a natural 20, for each
nonlegendary creature you control, create a
token that's a copy of that creature.
