Goddess Verdande's Guidance

When this enters the battlefield, look at the top
three cards of your library. You may reveal a
Warrior, and if you do add it to your hand and put
the rest back in any order.
While you control a Warrior, at the beginning of
each opponents up-keep, you may declare a card
type then that player reveals the top card of their
library. If the revealed card is the declared type,
mill it.
