Knight of Grudges

First strike
Whenever a creature dealt damage by Knight of Grudges this turn dies, you may pay {b}{r}. If you do, exile that creature and return it to the battlefield under your control at the beginning
of your next upkeep. It gains haste. Sacrifice it at the beginning of the end step.
If you still have unfinished business after your death,
he can give you a second chance.
