Neutral jump can be very annoying against TJ. Believe me. Lol. Tremor isn’t effective against it. At least, not as an anti air. You can read that neutral jump and shoot toss, or light tremor from the outside to get a hard knockdown when the opponent lands. I will often bait my opponent into jumping by throwing out a power line and cancelling it and then light tremoring them when they’re landing for the knockdown. Or, if you have meter, you can powerline to roll and then shadow uppercut while your opponent is still airborne (I do this all the time against jumping Glacius). You CAN definitely flying knee a nuetral jumping Sabrewulf.
One more thing. You can jump in yourself and use heavy punch to neutralize an opponent’s neutral jump. If you read your opponents jump well enough, you can even do a lp+lk flipout, which I can execute pretty well in stage corners.
P. S. Rebelo’s TJ is the only TJ I’ve seen that is/was definitely better than mine. So, I have a little bit of experience with the character.
