There’s a new strategy article up on Sonic Hurricane explaining the general concept of using attacks to bait supers and Custom Combos. Here’s the link along with a brief quote:
Using Combos and Block Strings as Bait on Sonic Hurricane
Valle somehow assembled the perfect storm. He built up an insane amount of comeback momentum. He used a combo that didn’t knock down, so it looked like he screwed up. It was only three hits, so it was tough for Choi to judge the distance in such a short period of time. It ended in a fireball which caused funky slowdown and messed with Choi’s timing. And it ended with Sagat standing up, which made him seem like a very tempting target for a Valle CC.
