Lazav, Shadow Broker

At the beginning of each opponent's upkeep, you may exile a nonland card face down from your hand. As long as it remains exiled, that opponent may look at it and cast it using mana of any color. When it leaves exile, you surveil 2.

When an opponent casts a spell exiled with Lazav, draw a card, then that opponent surveils 2. Permanents you control gain hexproof until end of turn.

{u}{b}: Return target card exiled by Lazav to its owners hand.
