The Promised Day

Search your library for the Philosopher's Stone and place it on the battlefield. Then shuffle your library.
Sacrifice all creatures on the battlefield. You may add +1/+1 for each creature sacrificed to the Philosopher's Stone even if it is not equipped by an alchemist. (The Philosopher's Stone cannot attack or block because it is an artifact. Each +1/+1 counter is added to the alchemist once it equips the Philosopher's Stone.)
