Hello, I have 2 questions. 1. I finally was able to perform Sako's combo and I want to know if there are any practical uses for it. Does it have any advantages compared to regular mawaru corner carry combos? 2. Is there any use for iad combo (or blockstring) patterns like this: ...5S, iad, -P- ,jS, -P-... Also can it be started with 2D, iad... (if opponent is blocking ofc), or there will be a window? Thanks in advance.
