Broodrage Mycoid [The Lost Caverns of Ixalan]

At the beginning of your end step, if you descended this turn, create a 1/1 black Fungus creature token with “This creature can’t block.” (You descended if a permanent card was put into your graveyard from anywhere.) As the massive mycoids known as rage titans charge into battle, lesser ones swarm in their wake, gobbling up any survivors.
