Wyvern Nestrobbers

Flying

At the beginning of each upkeep, create a 1/1 red
and green Dragon creature token with flying and devour 2. (As the token enters the battlefield, you
may sacrifice any number of creatures. It enters with twice that many +1/+1 counters on it.)

"Wyverns are great. Sure, they can't pretend to be a king or become a lich or anything like that, but mine can do a backflip."-Artorias
