Fungus

The Lost Caverns of Ixalan Tokens

As the massive mycoids known as rage titans charge into battle, lesser ones swarm in their wake, gobbling up any survivors.

Broodrage Mycoid

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.)

"It's no good killing them? Then what do we do? Distract them with a tea party?"
—Mervin, Brazen Coalition prospector

Synapse Necromage

When Synapse Necromage dies, create two 1/1 black Fungus creature tokens with "This creature can't block."

The Mycotyrant

Trample
The Mycotyrant's power and toughness are each equal to the number of creatures you control that are Fungi and/or Saprolings.
At the beginning of your end step, create X 1/1 black Fungus creature tokens with "This creature can't block," where X is the number of times you descended this turn. (You descend each time a permanent card is put into your graveyard from anywhere.)
