Might as well talk about Magic related stuff here. I'm going to go through the process today of trying to recover my gems from the closed beta and then start working towards that mono red deck that's just straight burn. I stopped playing Arena for awhile because I had amassed a really decent collection of rares and mythics, had a really good mono red deck, a UW control deck with Teferi, and a green stompy deck and when all that went away, I was kinda annoyed to rebuild that collection.
I may as well jump back in though, even if it's to draft. I liked drafting on Arena more than Magic Online except for the BO1 format. Drafting with paper magic remains the best.
The other big drawback to arena is the lack of anything other than 1v1. As time goes on a collections get bigger I would hope that there's a way to include 2 headed giant with cube drafting.
I also still play paper Magic, but mostly modern. I typically pilot a RG ponza/land destruction deck because I'm a bastard and casting Bloodbraid Elf and cascading into Stone Rain, Molten Rain, or Blood Moon is the best.
