Anastasia of Rotten Lilacs

Whenever a player mills cards, you may exile one nonland card from among them. At any time, you may sacrifice a number of Saporlings equal to the mana cost of a card exiled with Anastasia to cast it without paying it's
mana cost.
Whenever one or more cards leave your graveyard, create a 1/1 Saporling creature token.
Whenever a fungus you control dies, each player mills a card (Saporlings aren't fungus).
