I'm not really a pauper commander player, but since commander has the biggest pool of cards to choose from, knowledge is key for building a deck. I'm always trying to learn more and more about commander and magic in general.
Everyday I'm trying to build a new deck, trying to find sinergies. What I'm currently doing is trying to compartimentalize the types of cards I can use. That being said, pauper commander is giving me the oportunity to find good common cards by narrowing my options. In Magic you can easily get lost while trying to do something.
What I'm mostly getting out of this is being able to build cheaper decks, and yet competitive.
So, by learning more about pauper, I'm actually building stronger decks, more focused decks and cheaper expensive decks, if you know what I mean.
I would be really interested in joining your discord
