Up-B out of shield for Wario is a very very bad idea. Too easy to smash DI out of it and punish Wario. The Wario was pretty good, just used Waft badly and never used Chomp.... Chomp is easy to combo into =/
Waft KOes at a 3/4 charge easier the a fully charged one oddly enough. Does less damage but does much more knockback.
