I was talking with a friend of mine and we were discussing about "MtG history". In my opinion, near 2018/19 most of the formats of MtG were in decline and the existence of a stable format created by the players like Commander is the reason why it has not become a more "niche" game. Instead my friend considers EDH something harmful to MtG, causing in these years a lot of power creep and the decline of more competitive formats, like Modern or Standard. Your opinion on this?
