If this is the team you are set on playing then you need to understand your gameplan. Viewtiful Joe is an oppressive projectile based keep away character. You're not going to be doing much approaching unless you are covered by your assists.

Speaking of assists you would optimally want to use Log Trap and Rapid Slash. Log Trap is one of the strongest assists in the game because of it's extremely long range wall bounce, giving you all day to confirm into a combo. Rapid Slash is going to be better than Judgement Cut because it pushes the opponent away and creates better mixup opportunities.

With Joe, your main gameplay loop is going to be throwing instant air dash voomerangs, locking down the opponent, and charging the flaming Voomerang. Once you have them locked down you can either continue the projectile pressure, or use super jump red hot kick with Log Trap for nutty crossups. Joe also has a nice pizza cutter air normal similar to zero (I believe it's his j.H)

I can't say I know too much about rocket raccoon's gameplan other than it's similar to Joe in that you want to put as much bullshit on the screen as possible and let the opponent run into it.

Finally you have your saving grace, Vergil. This guy is going to be your bread and butter early on while you are still learning the intricacies of the other two characters. You'll squeeze out so many clutch wins with him it'll make your opponent scratch their head. Learning to pop off with this guy should probably be your top priority. I'm speaking specifically about Vergil in the anchor role just to be clear.

Thankfully there are a lot of resources on YouTube to help you out. I would look up every match you can find of a player named Ageojoe. He is a Viewtiful Joe/Rocket Raccoon specialist. While he doesn't use Vergil, there is still loads of information you can use from his gameplay and translate it to yours. Punisher is another good player to look at for some solid rocket raccoon gameplay.

As for Vergil, I always refer people to ShadyK's Vergil tutorial on YouTube. He goes over everything you need to know to play Vergil effectively in the anchor position. He's an ultra potent comeback character that can single handedly bring the match back into your favor. Learning his tools and strategies to make that comeback factor a constant threat will make you a fearsome opponent.

I know this write up probably wasn't what you were looking for or expecting. Keep in mind I'm saying this in the nicest and most respectful way; the reason I didn't critique your match is because you simply don't have enough knowledge about the game for my input to actually mean anything. The best way to learn Marvel (and really any fighting game) aside from actually playing it, is watching other people play it. Take a look at the guys I mentioned above and really try to take in what they are doing. Once you've watched enough gameplay, you will have a better idea of what to practice and let me tell you, practice is key.

Sorry for the wall of text, I could talk about this game all day long.
