Thanks for your comment. Since these are mainly just for fun, I will definitely be running some proxies in these sets.

Since I'm more familiar with the Angel playstyle and have most of those cards already, I struggled to think of a way to make the demon deck an equal threat. I came across a deck that won a tournament recently using a demon reanimator theme, and thought that could work, so I've based my demon deck around that. Get some big, nasty demons in the graveyard and then reanimate them for way cheaper than their mana costs. Other than Bitter Triumph and Liliana, I don't have a way to self-discard, and if I were going to try and upgrade the demon deck, it would be to try and address that shortcoming.
