Also, a new mode (The Subspace Boss Rush) where you can't play as Tabuu because he recruited Master Hand, Crazy Hand, Master Core, the stage bosses, and the Subspace Bosses to fight you in a continuous battle.

I have a really hard time believing Tabuu would be playable, as well as Nintendo not giving you access to a character during a mode. And wouldn't the mode be called "Boss Battles" since that was what it was in Brawl? Good idea, though, just needs some tweaks.
