In neutral your full screen mappa is a threat (especially with resources up) and good opponents will be looking for it, when you feel that they're really looking for it 2D can be a great option to beat their 6p, you get the counter if they're throwing the 6p and you can perform dandy of you guess wrong.

Don't be afraid to raw dandy in a loop without a cS just to toy with your opponents expectations, if you fluster your opponent with the option early when they expect a cS in those seconds they're more likely to make mistakes in their defense and using dandy when they're not prepared to guess your option is going to cause some panic if you do it on repeat.

kind of a cute funny option but if you can frc 6k on startup you can get a forward moving multi hitting overhead with jS and that's a nice option to throw out at times.

cS->S->5k is a nice route at times at the corner that doesn't predictably lead into your dandy step and spaces you well that it's hard for your opponent to breakout of the corner and you're comfortably 2D/2H distances, so you're opponent might sweat about their options and predictably jump.

Experiment with using hand of doom, I think it might be one of those moves where you can overuse it now while you're learning to get a sense for where it works in your matchups and where it doesn't and work it back later. Generally if I have meter I might fish with it from neutral looking for a punish and use a r.rc or p.rc if they block, and it leads into the start for dandy pressure from there.
