Vast-Horned Strix

Flying, trample
At the beginning of your draw step, Scry X,
where X is the number of +1/+1 counters on
Vast-Horned Strix.
Whenever you scry, you may pay {x}. When you
do, put X +1/+1 counters on Vast-Horned Strix.
Forethought spares afterthought in the mind of the
giant horned owls of Moonvale.
