For many years I didnt play at all, my cards were just in a box. Few years back I got them out, got everything registered using Delver Lens and started collecting a bit again. Recently two people in my boardgame group hit their heads and can't do really long thinky boardgames at the moment, so we've settled on mtg as a social and still challenging compromise.
We play some of my budget legacy decks, we play a bit of jumpstart, and we're just starting to get into commander.
