As a player of commander, it's my first time seeing a ban of a legendary creature in the format... At least one of this magnitude.
It's common for them to ban a legendary creature from the game instead only from the helm of decks? Why not ban Golos only as the commander? Is it for the sake of semplicity and communication? (Is it not the same case for... Who was it?...Erayo?)
I would gladly listen to your opinions, I'm a bit puzzled.
I would have played it gladly at least in the 99 of some low-power land-matters deck, for examples. Or as a hidden commander of a shrine deck, as the one guy that travels through all of them.
Anyway, have fun guys!;-)
