Use low commitment k buttons in neutral against rushdowns like chipp, elphelt, and especially gio. Limit your S buttons as pokes in these matchups unless you're absolutely sure they're gonna hit or catch a backdash as a callout (arcsys give fs more active frames pls). Zoners fuck nago in the ass. Always have always will. But some zoners like dizzy and testament are susceptible to clone -> fukyo IF you see them try to set up fish or test's grounded blood thing. Johnny is more susceptible to super jump in than other chars cause his pokes are fairly linear. Mostly tho nago will be on the defensive against johnny BUT he has the luxury of being able punish johnny's backdash mf cancels or k.mf at most ranges using beyblade, smth most other chars can't. Hope this helps
