Theros or Ravnica D&D 5e (Low Combat)
I’d be willing to play in either, but I could consider running a Ravnica game. I have that book but not Theros, though it’s been a while since I’ve DMed anything. I haven’t tried running a 5e campaign yet, so starting small to test the waters would be ideal for me too. Light combat might be a tad tricky since the system is designed around combat, and it’s a huge theme in both D&D and M:tG in general. BUT, I think we can simplify it by not having random combat encounters, avoiding mook-fights, and everyone working together to use alternate approaches to resolving encounters (i.e., no one plays a character that attacks first and asks questions later).
