Going for the tenshin after a blocked jab is also one of my main “setups” for the tenshin. The blocked jab can come from anywhere really, like after a crossup, after a cr.lk or even meaty. Where there’s a jab, there’s an opportunity to use a tenshin.
Using the command grab as meaty on the opponent’s wake up has also been really profitable for me. I just have to set the tone for it. Once I feel like he’s scared and he’s just gonna block after a knockdown, BAM, 250 dmg (at least), thank you very much. Just to give you a specific example:
You know that situation in a round, when you score a knockdown, the other guy has the life lead, but you can kill him with a combo, so he’s not gonna risk the reversal and he can’t quite chip you, but he can kill you with a single medium or hard normal? Well, 9 times out of 10 I will land that meaty tenshin and I will take the round.
Also, if I’m feeling really cheeky, I stop my rekka series after the second one and go for the grab. But I usually leave that one for casual play while goofing around, when I have the nerve to pull that off.
