While I was messing around in training mode against Ragna, I've found that after the Collider, 6C, 5D, I could to another Collider, and catch them if I release the button as they fly by, and do another 6C, 5D into another Collider.
Is this punishable by the other character's air normals/specials in a regular match?
EDIT: Now that I think about it, any character with an arial that sends them flying into the ground (Rachel's j.2C, Arakune's j.2A/B/C, etc.) can get out of this.
