I haven't seen any other Natsu player do this, so I just wanted to share it. After I land a 22_88B, my go-to combo, instead of the usual 66B BE 1A, is actually, with fastest inputs, 6KA 6A+B4 PO A+B. It's a hefty chunk of damage, most of it coming from the surprise exorcism on wake-up of course. Air control wrecks this to the point where it ends at 6A+B, but I have a surprisingly high success rate with this, regardless of how easy it is to escape.
Okay, so this doesn't have much practicality outside of beating on the training dummies or those who choose to put down their controller and read the news when they get launched into a juggle, but it's possible to juggle someone for a very long time, pretty much Viola style. It's like this:
22_88B 6KA 6A+B4 PO A B[K]4 PO A 6KA 6A+B4 PO A B[K]4 PO A and so on. Getting all of what I wrote there on someone, you're looking at around 120 damage, where each hit does like almost nothing due to the damage reduction as the combo hit-count rises. I've also had some success with this online, usually resulting in "this is why Natsu is OP" or "wtf was that" messages in my inbox a few moments after the match. Either way, it might be worth the laugh in training mode or against a friend who wants to see some crazy shenanigans.
It's important to remember when trying this is that you have to input it all as fast as possible. Slight delays allows the opponent to edge closer and closer to the ground before the fun ends and you're looking for another 22_88B.
