Kenshi, Psychokineticist

Hexproof
At the beginning of your first main phase, exile the top card of target opponents library.
If the exiled card is a land, put it on the battlefield tapped under your control. If it’s a creature or planeswalker, you gain life equal to its converted mana cost. If it's an instant or sorcery, you may cast it, if you do copy it, you may choose new targets for the copy. If it's an artifact or enchantment, you may cast it without paying it's mana cost.
