Vault 112: Sadistic Simulation (Fallout)

Enchantment Ñ Saga - (As this Saga enters and after your draw step, add a lore counter. Sacrifice after III.)
I, II Ñ Tap up to one target creature and put a stun counter on it. You get {E}{E} (two energy counters).
III Ñ 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.
