Vault 112: Sadistic Simulation

(As this Saga enters and after your draw step, add a lore counter. Sacifice after III.)
I, II — Tap up to one target creature and put a stun counter on it. You get EE (two energy counters)
III — Pay any amount of E. If you paid one or more E 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.
