Acolyte of Phanuel

When Acolyte of Phanuel enters the battlefield,
look at the top 2 cards of your library. You may
put any number of them into your graveyard and
the rest back on top in any order.
At the beginning of your upkeep, if Acolyte of
Phanuel is in your graveyard, you may pay 1 life.
If you do, return it to your hand.
