Freedon Nadd, Sith Sorcerer

Flying, Persist (When this permanent is put into a graveyard from the battlefield, if it had no -1/-1
counters on it, return it to the battlefield under its
owner's control with a -1/-1 counter on it.)
Hate — at the beginning of each End Step, if an opponent lost life from a noncombat source this
turn, untap Freedon Nadd and have him deal 2
damage to target creature, planeswalker, or player
{b/r}, {t}: Deal 2 damage to one target.
