This isn’t new knowledge, but it is less widely known than it should be: holding down-back (barely above the down-back corner) on the gray stick in crouch will continue the crouch while causing any A input to immediately jab. This is amazing for a character like Ganon with a very good jab AND heavy need to use CC.
Even better, the same spot is located within the range of B-Air. Thus we can B-Air AI into instant crouch-jab on platform, or crouch in front of miss tech/shield, B-Airing a roll behind, jabbing a reactable in-place option, and hard-punishing anything laggy that we crouch cancel.
Vitally important tech is dash -> hold C-Stick down -> release C-Stick + crouch within 2 frames of entering run -> jab within 2 frames of entering crouch. It’s a quick and long ranged ground poke, and it allows ASDI down to be active almost the entire time.
