This is a video I wanted to put together myself since I've been abusing it heavily over the past week or so -- just check some of the recent matches on the iPlayWinner YouTube Channel. MVC3CrackTV beat me to the punch though, with MegamanDS and Fanatiq uploading what is easily one of the more cheap tactics to be found in the game so far. Check out the video and details on how it works below.

The basic gist is you are exploiting the DHC trick to reset the hitstun. This results in being able to Aerial Tag over and over again. A practical application of this is starting a combo with Sentinel, Aerial Tag to Storm, Exchange the opponent to the ground and use her Elemental Rage to start to the DHC trick. From here, DHC to Sentinel's Hyper Sentinel Force, relaunch and start the entire process all over again. This is a pseudo-infinite as the opponent has to break out of the Ariel Tag to stop this chain of events. Generally, you only need one or two Aerial Tag's to end up killing off the other character.

Thanks to Danny for the tip on the video.
