Um I would say in total he/she looked about 8-9 ft? I assume his costume added to his/her hight. The last question I wouldt know, it was dark and the costume draped down where you couldn't see what he was standing on. Haha
I use Jolt Haymaker to avoid projectiles, like when I was facing your Link. Otherwise I prefer dashing, using jabs and tilts. Approaching can be hard for Mac, but once he gets close he has a huge advantage. I've been plain since Brawl, so I know a bit of stuff, like DI and VI. If you want to be more active with Smash, there's great site called Smahboards. I actually have an account there.
