Nicol Bolas knows all With Heartless Summoning and Shirei, Shizo's Caretaker on the field cast Perilous Myr which would die due to a state-based action causing two damage as you please. Then at the end of the turn Shirei would bring the Myr back and it would die again, only to have Shirei bring it back at the end of your opponents turn. Another route is with Godhead of Awe, heartless summoning and an equiped Shirei cast necropede to remove all opponents creatures.
