Conquest of the Angel-Guard

(As this Saga enters and after your draw step,
add a lore counter. Sacrifice after II.)
I - Search your library for two Angel cards,
reveal them, and put them into your hand. Then
shuffle your library.
II - Exile up to one target creature an opponent
controls. When you do, put an Angel creature
card with equal converted mana cost to the exiled
card from your hand onto the battlefield.
