is there any tips that i could do/ follow that would help make my two button execution better with things like air dashes, supers and things like that?
I’m not to sure what you could do to get better with 2 button executions. Are you on a pad or stick? Do you claw or slide? I think it’s solely based on experience. A lot of people that probably do have trouble with doing 2 button execution is that they end up pressing more than 2 buttons, like you try to ADDF+LK but actually pressing it all at once.
You could try going in training mode and just dash on the ground for a few reps. D+PP and see where you at you could also get Sent and just do fly and unfly as much as you can too but like I said I think it’s solely based on experience.
Okay so the trick is you hit both of the buttons at the same time.
i play on and pad but when i press two buttons, one of the two buttons that i pressed will come out but not what i was trying to put out
Come on man… 
Pad? Man… you gonna be a pad player? It must be hard already to hold the pad in a comfortable position but anyways if your pressing both buttons and one is coming out then that means that your pressing one before the other, your not doing it simultaneously.
Go in training mode like I mentioned before and just dash back and forth:
:r:+:2p:
:d:+:2p: (Most folks use this to do multiple dashes)
:l:+:2p:
^That should give you an idea and help you with pressing them both cause if you don’t then you’ll do an attack instead of a dash.
