I currently have an infect deck that has Yawgmoth, Thran Physician in it. It's currently golgari, but I plan on gradually branching into more colors until eventually having Atraxa as the commander. As i'm working on potential lists for moving into abzan colors, i'm finding that the deck's focus is moving in a direction that makes Yawgmoth feel less useful in the build compared to some other options.
So, I had an idea; a commander deck with Yawgmoth at the head that primarily focuses on utilizing cards centered around "Old Phyrexia". That being said, i'm not sure what direction to build in. I know that he's at his best as an aristocrat deck, but i'm having trouble finding older/thematically
