I've been using Archidekt. I really like the built-in playtester, but the interface can be kind of sluggish, and some of the design decisions, especially around categorizing and sorting, are quite clunky.
I know there are a lot of options but I haven't tried any of them. Are there any that you'd recommend?
After trying them all, Moxfield is by far the more mature product in my mind
It's been a while since I've used it, but the site "clicked" with me quickly. I used to be an avid tappedout user
