We use to have team modes on mtgo. I think back in 2015 with origins they removed 2hg, 3gh, emperor, and every other popular format that they deemed too much work, using the excuse of "they weren't popular" which if anyone played 2hg back then would know it had one of the biggest player bases. Mtgo devs just didn't want to have to code extra for interactions, but hey to pacify us they gave each account a free magic origins draft
