there's an example of:dair's usefulness, good shield pressure, good teamwork, and good stage awareness (this may not be evident but I did uthrow shine because I knew falcon was coming to whoop my *** and wanted to displace my location fast. Perhaps there was a better choice here?). Notice also that the dash attack was fast but put us both in a laggy state. Running waveshine/dash cancel jab/dair would have been better. We all know these gameplay nuances or at least understand the importance of doing little stuff like this
can we talk about fox's team game a little bit?
Fox's versatility in teams is remarkable. I love that he's such a 1v2 juggernaut; he is also great at surviving by virtue of typical opponents having weaker gimp games in doubles. He excels at racking up damage fast and is among the best in the game at breaking combos off early to stay safe (refer back to the video example, there are lots more possibilities). He moves fast [horizontally and] vertically so he's able to save teammates before they leave the blast zones with dair/fair. He can save allies very safely by firefox stalling on the ledge to catch their air dodge/short recovery. He has great, reliable, and precisely aimable kill moves [bair, uair, usmash] that ensure very fast kills out of teammates grabs/laggy moves. He can play aggressive, defensively, and territorially (referring to zoning/spacing)--AT THE SAME TIME. The limits are your own brain and reaction time.
