Each player may draw an additional card during their draw step. If a player draws an additional card this way, that player puts the bottom card from their library into the graveyard. Then that player may put a 1/1 Fungus creature token onto the battlefield under any player's control. The player who has the Fungus token enter the battlefield under their control puts the bottom card of his or her library into the graveyard.
