Ezmerald, Succubus Usurper

Pay 2 life: Exile the top three cards of target players library. Until end of turn, you may play one of those cards. Activate this ability once per a turn.
Tap five untapped permanents you control but do not own: Target player loses 10 life.
When Ezmerald dies, gain control of target permanent unless its controller pays {3}, or discards a card at random.
