Building an infinite combo is one of the flashier ways to win in Commander, but it's important not to telegraph what you're doing. If your opponents see Niv-Mizzet, the Firemind, they're going to expect you to play Curiosity, and resolving either part of the combo is going to be a challenge for you.
This deck avoids detection by using Kess, Dissident Mage not as a combo piece but as a way to find and recur combo pieces. If your opponents counter one of your plans, no problem: you've got many more ready to unleash.
There are too many ways to win with this deck to cover them all here, but here's the "formula" with the most redundant pieces. See how many others you can find.
