Quaithe, The Shadowbinder

{1}{u}, Scry 1 and you loose 1 life.
At the beginning of your end step, reveal the top
card of your library. If it's a non-land permanent
that shares the same color with the last card you
cast this turn, you draw that card and each
opponent looses life equal to that card's
converted mana cost. Otherwise, put that card
into your graveyard.
