Bargain for Power

As an additional cost to cast Bargain for Power, pay 5 life.
Choose up to one target creature you control, exile all other creatures you control. That creature gains hexproof, indestructible, and deathtouch until end of turn. Exile that creature at the beginning of your next upkeep.
You will be spared, for now, but others must pay for your misdeeds until then, Wernix.
