I play commander pretty much exclusively because I sold my collection years ago and don’t feel like building back to it. I buy precon decks and have several people in my life that play so we get to it. One of my favorites is my son and I blaze up then play for a couple hours. Tons of fun.
I don’t play on arena. I’d have to build an account, but I’m not opposed when I’m not on the road for work.
