Slimefoot, W.light Janitor

Whenever a Swamp or Forest enters the
battlefield under your control,look at the
top 3 cards of Slimefoot's spellbook,
choose 1 and put that card into your hand,
then put the others on the bottom of Slimefoot's spellbook in a random order.
If the spellbook is empty create a
1/1 green Saproling creature token
for each type of basic land you control.
