If you would gain life, instead mill that many
cards.
If you would draw a card while your library has
no cards in it, instead exile a nonland card from
a graveyard. You may cast that card for as long
as it remains exiled, and you may spend mana
as though it were mana of any type to cast that
spell. Spells cast this way have Delve.
