This gives you free reign to do whatever you like on your turn, with the only things you need to worry about being an instant-speed Planeswalker ability (like Teferi, Master of Time) or a land's ability (like a channelled Eiganjo, Seat of the Empire)
Since youre in green and white, you have access to all sorts of protection spells like Heroic Intervention and Teferis Protection, letting you keep your commander nice and safe while you disrupt your opponents plans
Not only are there equipment cards already out there that do something powerful, interesting, or utilitarian, they also give you a little bit of incentive to play that old deck
It also comes with the chance at opening some great new cards for Magics premier multiplayer format, Commander
Also, that statements patently false in Magic anyway
