(As this Saga enters the battlefield and after your draw step, add a lore counter. Sacrifice after III.)
I, II — Tap up to one target creature and put a stun counter on it. You get {E}{E} (two energy get counters).
III — Pay any amount of {E}. If you paid one or more this way, shuffle your library, then exile that many cards from the top. You may play one of those cards without paying its mana cost.
