Doubt anyone has discovered this yet, I was messing around V Tager in training mode and if you get the timing juuuust right you can combo 6C jD 2B 623B 6C (sliiight pause) 623B 6C 623B for a massive 4.3K meterless (If you opt for another 623B instead of jD you get 200 more, but one less seal). Works as a fantastic burst rapid block punish (Does about 6k post burst lol) or as a psychic 720 punish (if you're halfway through 6C you can't be grabbed)
It's situational as all hell, though I discovered you can start it with 2B or even 5D as well (do 5D 623B 2B etc). Definitely a flashy hype combo to add to the v Tager list.
EDIT: Also works from 623B for 4.2k. :o
EDITEDIT: From 5A, 2A or 5B you can 5B 2B 623B 2B 623B 6C 623B for 3kish.. Probably the best you can get on a crouching Tager, and it's equivalent to the standard Tager specific, 5A 5B 2B 6C jD 2B 623B 6C 623B . Might be a new Tager BnB all around. :]
EDITEDITEDIT: Nevermind, if you start with 5A, 2A, or 5B and he's standing, go for the normal, the alternate gives you 200 less damage, and won't even hit on 5A 2A 5B etc. However, it's a great safe follow to 2B instead of risking him being crouched and whiffing the 6C, and you only lose 500 damage from the most most most ideal alternate one.
4EDIT: Also works 5C 623B and 6A 623B.
