The Creation of Mewtwo

(As this Saga enters and after your draw step add a lore counter. Sacrifice after III.)
I & II: Put a token onto the battlefield that's a copy of target creature, except it's a 1/1.
III: You may search your library and/or graveyard for a card named Mewtwo, reveal it, and put it into your hand. If you search your library this way, shuffle it.
