Rootscape Sanctuary (v.2)

Skip your draw step.
At the beginning of your upkeep, you may pay
any amount of life to mill that many cards.
Once during each of your turns, you may cast a
spell and/or play a land from your graveyard. If a
spell cast in this way would be put into your graveyard as it resolves, exile it instead.
Exile a card from your graveyard: gain life equal
to the exiled card's mana value.
