Sister Friede

When Sister Friede dies, create a Legenday 2/1
black Human Rogue creature token with first
strike named Sister Friede and create a Legendary
3/3 black and green Zombie Giant creature token
named Father Ariandel with trample.
Whenever another creature named Sister Friede
or Father Ariandel dies, if Sister Friede is in the graveyard, you may return Sister Friede from
your graveyard to the battlefield transformed
under its owner's control.
