Pauper is one of my favorite formats. I like brewing unique builds. I have made a mono green midrange, black burn, mono blue tron, izzet blitz, and even an orhzov extort deck. The options are endless.
Exactly right. Fun on the cheap. Decks can be built for as little as 10 to 20 bucks. I've built several from my bulk and have the most fun brewing and testing different builds.
