I'm playing Arena most days. Haven't spent any actual money on it and don't plan to. I'm using Lutris on Linux; I can't say that setup or maintenance have been painless, but it's working for me for now. I used to play MTGO years ago and would eventually like to get back to that because it's the best platform for Pauper.
Pre-pandemic I used to do both FNM drafts and kitchen table Magic with friends, and I would love to resume both of those, but I really don't think it's prudent yet, from a public health perspective.
