The Loathsome Dung Eater

Menace
If a creature dealt damage by Dung Eater this turn would die, exile it instead. When you do, create a seedbed Curse token. (It's a black enchantment with no text.)
At the beginning of your end step, if you control 5 or more Seedbed Curses, exile all Seedbed Curses you control. You get an emblem with "If a creature would die, exile it instead," and "Creatures lose all abilities, gain menace , and are Omen in addition to their other types."
