SHYVANA, DRAGON FORM

Flying
Challenger (My owner chooses a target creature
to block me)
When I flip, Devour 2 (As this enters the battlefield, you may sacrifice any number of
creatures. This creature enters the battlefield with 2
times that many +1/+1 counters on it.)
I keep all +1/+1 counters when I flip.
When I attack, give me +2/+2 until end of turn.
