Himatora, the Spirit-Sister

{2}{w/b}, {t}, Sacrifice another permanent: You may
exile a permanent card that shares a type with sacrificed permanent from your graveyard. If you
do, create a token that's a copy of a permanent
card of that type you own in exile. Exile that
token at the beginning of the next end step. Otherwise, surveil 2 and you gain 2 life. (Look at
the top two cards of your library, then put any number
of them into your graveyard and the rest on top of your library in any order.)
