While hitting the lab, Infrit and Miniboss dug up some old MvC2 tech that may seem very plausible in Ultimate Marvel vs. Capcom 3.
It looks like when you kill a character near the corner, you can “tri-dash” over the corpse which causes you to face the opposite way as if the corpse were still alive. After this, you can then jump up/forward and dash backwards with an attack on the incoming character, giving you a chance to pull off a very ambiguous crossup.
This tech may not be new but if you didn’t know about it, it’s worth incorporating it into your regular gameplay. It’s not hard and can deem to be very useful. Take a look at the video and subscribe for more.
