Here is where things get complicated and Bolas rears his ugly head. On my board at this point, I had Yannik, who had eaten a Lumbering Battlement and a Knight of Autumn. I had Felidar Guardian in my hand. I'd made a deal with Thrun to focus on Niv-Mizzet, who was in a winning position, so I thankfully made it to my next turn. I played Felidar Guardian, which blinked Yannik, returning Lumbering Battlement to the field which ate the Guardian and Knight of Autumn. At this point, it became clear to everyone that I'd gone infinite because, when Yannik returned to the field, he could eat Lumbering Battlement and start the chain over again. Thanks to the third ability on the Knight, I not only could make Nikara infinitely big, I could also gained an infinite amount of life.
