Following the example of other threads, if you have a good combo, technique, or some tidbit of knowledge not posted, feel free to contribute (after I “complete” the OP with my own info). If there’s a better version of the combo you posted then I’ll use that and make note of it (you’ll still be credited).
jayson.boss: I feel the best way to play him is patiently. Even though he falls faster than other characters, has good dashes, and an amazing crossup, he still has a hard time hitting people with good defense. You mainly want to carefully place your air attacks, occasional Tek Wins/Lancers, and assist to help you create an opportunity. Once you get it you want to rack up as much damage as fast as possible, because chances are they know how much damage they’ll eat and will try to mega crash you. Keep creating opportunities like these so that they’re forced to keep wasting meter for mega crash instead of supers/counters and you can control the match.
Double windmill in the air is done by jumping after the first one ends, then immediately canceling the jump into the second one. You can only do one windmill per jump. It is also possible to do a 3rd one after baroque (since baroque gives you another jump), but it’s not very useful unless it will take out a character guaranteed.
Like said, his assist helps pretty much everyone extend their combos and is very flexible. It also controls a great amount of space from far.
I’m not so sure about Polimar, but it might be a good team. You’d have to just experiment, or wait for someone more savvy to comment.
