Herald of Wärnstorm

Menace, Trample
When Herald of Warnstorm enters the battlefield
Scry 3, then reveal the top card of your library.
If it's a creature card, you mobilize X where X
is that creatures power (Put X +1/+1 counters on
a white Army you control. If you don't control
one, create a 0/0 white Human Army creature
token first) and you gain life equal to its
toughness.
