Vendetta (Whenever a creature you control is dealt damage by a creature an opponent controls, you may pay 1 and sacrifice a creature. If you do, destroy that creature.)

Whenever a creature an opponent controls dies, put a +1/+1 counter on Sheriff Seven Fingers.

At the beginning of your upkeep, if you control five or more creatures with +1/+1 counters on them, create a 2/2 white and black Human Rogue creature token with vigilance.
