So, anyone who's seen Padtrick team knows how effective Vergil/Strider can be. That combination effectively shuts off most aerial maneuvers as, unlike Dante, Vergil can cross up an airborne opponent without exposing himself to too much danger, since his M teleport will leave him on the ground but behind the opponent, as opposed to Dante who always appears above and could be thrown or otherwise hurt. So you can very easily get that hard knockdown with Strider if your opponent is jumping around. The tradeoff for that is that Vergil doesn't have a way of converting that into a combo on his own without X-Factoring (hence Padtrick's early use of X-Factor in nearly every game).
I had previously thought that if a character had a crossup teleport, it either had to have a certain degree of vulnerability (Dante) or that character would not be able to convert into a combo easily (Vergil, Dormammu, Wesker in so much as he can't do it from all the way across the screen). But now I've realized there's Rocket Raccoon. His ground teleport lets you cross them up just like Vergil, but the difference is that he can Bear Trap his way into a full combo.
So this makes me theorize about possible RR/Strider teams. It seems like RR might have to be the point on that team, and you'd probably want someone pretty beefy in the second slot to make up for the fact that you're playing two of the lowest health characters in the game. Dante would actually go well with RR if you put Dante in the first slot, and you might even be able to get a pseudo-Kusoru type thing going if you Devil Trigger, since that would grant Dante a triple jump like Viewtiful Joe's. But Dante's health is only 900k, so that's leaving the team pretty slim as a whole.
The other issue is that even though Rocket can convert into a combo off the Strider assist, I don't know how difficult it would be to do any kind of real damage off that. His combos just don't hurt that much.
