Ambitious Necromancer

Fear (This creature can't be blocked except by artifact creatures and/or black creatures)
Zombie creatures under your control have fear.
Whenever Ambitious Necromancer attacks or
blocks, each opponent sacrifices a creature. You
create a 3/3 black Zombie creature token for each creature sacrificed that way.

my friend."
