Sindel: Anti-Sheeva Technology
I mentioned this a few months ago. If timed correctly, hair whip can be used as a counter to Sheeva's tele stomp. There is enough time to do this on reaction. It doesn't matter if she lands on top of you, in front or you, or behind you. If Sheeva does try to go behind you she will get hit by a scream. If Sindel's back is to the corner Sheeva can continuously stomp her from behind. You have to use a different strategy to get out of that situation (such as U4).
Note: Don't use this online. You'll get crushed over and over again.
