Fornem, Dark Seer

{1}{u}{b}: Fateseal 2 (To fateseal 2, look at the top
two cards of an opponent's library, then put any
number of them on the bottom of that player's
library and the rest on top in any order.)
{2}{t}: Exile the bottom card from target player's
library. You may cast this card this turn, you may
spend mana as though it were mana of any color
to cast that spell.
