Too bad these weren't in the 3DS version, I've done the latter with everyone and the former several times already.
I really wish that the harder challenges were more tolerable, as
there's even one intensity level 9.0 challenge where you have to complete that intensity within 12 minutes with Marth. Sure, Counter may be helpful against Master Core, but you still have to get past the monsters that come before it. And of course, there's the Master Fortress portion of the battle as well.
Anyway, this game really overdid it with the challenge difficulty, as not even Brawl had that many absurd challenges; the only Brawl challenges that were Golden Hammer immune contained rewards that are affiliated with the Subspace Emissary.
