Balor, the Evil Eye

Flying, vigilance
Opponents and permanents they control lose and cannot gain ward, shroud, hexproof, or protection.
At the beginning of your turn, tap a single permanent controlled by an opponent. Put a stun counter on that permanent.
Whenever a spell you control targets one or more permanents controlled by an opponent, draw a card.
If an effect you control would cause you to lose life, instead surveil that many cards.
