I noticed something about his b214 into behind portal that I wasn't aware of. The portal will track them even if they tech roll, forcing them to have to wake up or tech roll jump out. If they are always jumping, then you can catch them with a teleslam every time, but the teleslam will only work if you catch them just as they're jumping. If you try to teleslam them on reaction, it will whiff. If they block the teleslam, they will still fall through, but it looks like they will be at a slight advantage. If they start to stand there expecting you to follow up with the teleslam, you start following up with the tackle and you hit the reset.
I found that against a character like sub, if they decide to start doing a wake up slide instead of jumping, you simply do FRONT portal instead after the b214, dash back once, and they will slide right into the portal. I believe this will work for Kabals nomad dash too.
