[Takara Tomy]  Storm Spriggan Heavy Keep'

From my testing, this combo can successfully stand up against V2 H X'. It could work as a potential KO defense with a smidge of attack

Tests:

S2 H Kp' (launched first, hard) VS V2 H X' (banked properly, hard launched, second to launch)
S2 win rate: 90%

This combo took down a good attack combo in BSC, but you can choose whether to use or say this is inaccurate, I don't blame you. you've never heard of me suggesting combos for something like this, so take my opinion with a grain of salt
