Day of Sickening

Mutate 5
Whenever you remove a time counter from your mutation pool, exile the top card of your library.
When the last time counter is removed from your mutation pool, sacrifice Day of Sickening. For each creature card exiled by Day of Sickening, create
a 3/3 Fungus Beast. Then, draw a card for each noncreature, nonland card exiled by Day of
Sickening.
