Just finished my first game with my Niv-Mizzet deck. During the game, one player summoned his general, The Mimeoplasm, and chose Mortivore to mimic, resulting in a 28/28 monstrosity that could result in a one-hit general kill. Everyone watched nervously, till it got to my turn, whereupon I played a card I'd drawn (and revealed) with Augur of Bolas. Yep- pulled the ol' Switcheroo with the Augur and his general. "That's a fair trade," he conceded, as everyone burst out laughing.
