I don't have much luck with just a standing 1 to AA but I do have a fair amount of success if I back dash 122 hatchet sometimes the hatchet connects and I can get a short combo or just a shoulder and sometimes it just whiffs depending on when u catch them and what part of the 122 connects.
His D1 i swear is crazy slow and never works for me I do it on accident and eat a full combo.
Whenever you can get it AA hatchet x3 1,1 122, shoulder, just looks boss. but fuck if my hatchet doesnt get stuffed 57% of the time.
