Boo!
I'm on M:TG Arena, too, though I don't like it as much as Magic Online. Too bad Magic Online doesn't work on my computer.
In Arena, I'm "TheOrgg." I don't know if friends lists are a thing on it yet.
Arena feels like it is intended to compete with things like Hearthstone and to kill any interplayer economy.
I was on here to show someone an example of how an interview should go, and thought I'd drop by the forums.
