Roar of the Foultongue

Destroy up to X target creatures, then for each creature that died this way put that many target creatures from any graveyards into the battlefield
under your control, they are black zombies in addition to their other colors and types.
"We lay low under dirt and stone,
as we wait to be free from flesh and bone,
the gift of life we mock at a glance,
with an army of us, you don't stand a chance."
— A cadence of the undead.
