Herald's Horn

As Herald's Horn enters the battlefield,
choose a creature type.
Creature spells you cast of the chosen
type cost {1} less to cast.
At the beginning of your upkeep, look at the top
card of your library. If it's a creature card of the
chosen type, you may reveal it and put it
into your hand.
