Executioners Cleave and Maul

When Executioner Cleave and Maul enter the battlefield, destroy up to 4 target non-artifact,
non-black creatures. Cleave and Maul get a -1/-1 counter on them for each creature
destroyed this way.
It's hard to imagine that those two ever got along.
I suppose it's because their both dead now.
Death does have a way of bringing people together.
