Slagshot, Diamond Overseer

Trample, First Strike
Whenever Slagshot, Dimond Overseer attacks, look at the top three cards of your library and put any number of non-land cards into your hand and put the rest on the bottom of your library in any order.
On the your post-combat phase, draw a card for each spell you cast this turn, then add {u}{r}{w} for each card you drew this turn.
