So I posted a video on youtube about the application of firefox in smash 4 as a sort of makeshift shieldbreaker. This is really good as fox because you can condition your opponent to shield by using things like bairs and up airs, then mix it up on them by throwing out a firefox. However, the opponent if aware of the setup will be able to roll out or spotdodge but as you can see in the video it can be a very effective and stylish way of racking up damage or the stock if they are unaware!
