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.
"The one...The one with the big red horn, the
pompadour. Elvis!"
