Reverse Kara Framekills

This is the deep end. Easily the most obscure, yet strangely present bug in EX1: Reverse Kara Framekills.

In short, you can "autocorrect" special moves backwards by intersecting two players' pushboxes on specific frames. This is easily done in the corner, but is liable to happen just about anywhere on the screen with the right setup. Very few characters get anything from an kara sequence, but Ken and especially Cycloid Beta both have practical setups that make this tech less than a novelty.
