Assists that let you relaunch both mid screen and in the corner easily.
Akuma B (Tatsu)
Felicia Y (groundbounce assist)
Wesker B (gun)
Wesker Y (the knee)
Assists that let you relaunch mid screen and in the corner, but are fiddly, or annoying to set up.
Hsien Ko A (the blades) Fiddly mid screen, doesn’t add much damage in the corner
Zero Y (dash punch) requires shadow super, doesn’t add much damage, fiddly.
Arthur B (Daggers) requires gold armour, doesn’t add much damage.
Joe A (Voomerang ) fiddly
amusing but useless.
Jill B (flying straight kick) Easy to combo and set up, but uses wall bounce, so you can’t connect super fully afterwards.
I tested everyone except Tron, who I forgot.
In all cases except Wesker’s gun, what I’m doing is landing, calling down & partner, then down and S, then doing the slide, and the assist is hitting the oponent after I otg, giving She Hulk time to recover and continue the combo. With Weskers assist, I’m pressing two buttons to dash, and the assist button at the same time, to get close enough for the assist to hit, then doing sweep -> launcher, and in the corner, calling the assist, and walking back so I can get the sweep -> launcher. There’s also several assists which hit, but don’t hold them in place long enough for you to fully recover, and you might be able to get them to work if you run cancel the slide, but I’m not going to test that any time soon. There are obviously also bunch of other assists which allow you to relaunch only in the corner, (Magneto B and Jill A both do good damage as an example) and a couple which only work midscreen.
Using single hit moves like Felicia’s assist, and Wesker’s knee add about 90k to a combo off of a sweep, multiple hit moves like tatsu and daggers seem to add about 60k, moves which hit a lot for not much damage like Hsien Ko’s, and Zero’s only add about 30k. Obviously they add less after a command throw or hit confirm combo, and will give a decent chunk of extra meter, since meter gain does not get scaled (even by the throw scaling modifier). I personally can’t do this after an air throw, since calling the assist makes your run -> slide that little bit slower, so unless it’s in the corner, where you can get a launch with a run canceled slide, then use this to relaunch, you’re out of luck, and I would expect to be too far away after a level three throw as well, although I have not tested this.
