Dynamism
Smash Lord
I like the MS but I think his UpB should have a similar arc as well. Slighly lower than kirby's but further, (almost like a short hop fair with DK.) His DownB should also have the ability to pause in the air at the peak and shift horizontally (a little further than bowser moves at the top of his jump) but it's slower and controlled. I could work as a good survival too is he had the slight hop into the slam even when he's off the ground to begin with.
