Well no. Even if Nirvana is in 3D range you're not always gonna be able to do the j.B-j.2C loop because Carl will be facing the wrong way sometimes. Incoming all of the other mixups that Carl is known for. Besides the unblockable setup is only exploitable on characters without a non mashable DP. I see a difference in the Carl players when I watch videos. I'm seeing different strats, and mixups and combos. For instance:
Even if Nirvana is no where near Carl and he lands a Cantible, he can teleport her, and then carry the opponent 3/4ths of the screen to the corner as seen in the video I posted
or
If you want to stay mid screen, thanks to 22D and 4D you can still do a strong combo and have the opponent stuck between the 2 of you for more fun.
I have ideas of how we can incorporate atleast 3 of Nirvana's moves in a combo.
