Kharis and The Beholder

“When Kharis & The Beholder enters the battlefield and at the beginning of your upkeep, create a 1/1 white Human creature token and make a charisma check. <em>(Roll a d20.)</em> <br>• If the result plus the number of creatures you control is greater than 11, put a +1/+1 counter on each creature you control. <br>• If the result is a natural 20, for each nonlegendary creature you control, create a token that’s a copy of that creature. <br><br><em><span style="color:red">This card features a Heroes of the Realm card back and is Not Tournament Legal.</span></em>”
