KRIS, THE NECROMANCER

Whenever another Zombie you control dies, if it
didn't have decayed, create a 2/2 black Zombie
creature token with decayed. (It can't block.
When it attacks, sacrifice it at end of combat.)
At the beginning of your end step, you may
sacrifice a Zombie. If you do, draw a card.
Soulswords here! Each one comes with a free zombie!
