Viego, The Ruined King

First Strike
When Viego enters the battlefield, create a 0/5
Black Mist token with defender, reach, and "This
token blocks each combat if able". As long as this
token is on the battlefield, Viego cannot be
blocked by more than one creature.
If a creature an opponent controls dies, you may
exile Viego and create a black token that is an
exact copy of the creature. When this token is destroyed, return Viego to the battlefield with a
+2/+1 counter.
