Beating Fox's sideB with MultiMrGi

Fox' recovery is something one should learn to exploit to make the match up more even.
Dealing with upB is fairly straight forward (but still complex to execute) : you either jump offstage to hit him off his wind up, or you arrow him to death.
Meanwhile, sideB is much more complex to deal with as it is quicker and doesn't wind up. But don't worry, MultiMrGi is here to help you.
