Something to think about, often when you have a particularly strict timing loop, people are mashing a lot harder to get out of it, and usually holding backwards too to auto block if they succeed in teching; what this sets up is some pretty funny tech trap moments, especially for lambda with this loop. Imagine with me for a moment, the following;
236C CH -> 5b -> [6a -> j214d] X 6
At this point, if my brief research is correct, all you can get is another 6A, and the next crescent blackbeats. However, if you dash up like you're going to continue it, deliberately drop it, and throw your air unblockable 6A a moment later, you either get;
236C CH -> 5b -> [6a -> j214d] X 6 -> RESET 6a > Crescent > [6a -> j214d] X 6 for a mind blowing 9k (Right? 4422, and another 4-5k?)
or
236C CH -> 5b -> [6a -> j214d] X 6 -> RESET 6a (Gets barrier blocked) > pressure
This is the same sort of concept behind my reset 5Cs that catch people all the time (More for Jame's understanding than anyone else); they only really work when I deliberately cut off the combo for them, instead of tack them on to the end. Your blessing with the loop is that EVERY part is the same, so people will get really nervous about teching out of it, AND that the loop is BY DEFAULT IN THE CORNER () which is the best place to AUB reset anyway
Obvious pros; you win/force burst if you succeed
Obvious cons; 6A isn't that great of an AUB, takes tricky timing, relies on your opponent's tech tendencies (so read them BEFORE you try it)
Thoughts, James? This could all be really stupid, just trying to help. I know little about Lambda, but I know all about AUB traps
