Honestly, I'd recommend taking them to an area where you can abuse platforms. Stay up in their faces and don't LET them laser you. Obviously this can't happen all the time, so WD OoS is another really good option. DD -> dtilt doesn't quite work. You're gonna have to have a WD in the middle, so think about spacing there. Also, if you were dsmashing, just be sure you're done run canceling before trying to poke.1. I am not sure on what to do with lasers. The only thing I can do is to shield but it's terrible. I heard that dashing and D-tilting works but i attempted this and I did a D-Smash by accident.
Work on your DI, especially mixups, for this one. If you see your opponent rushing you, you need to know your reactions. If you think they'll grab, grab before them as yours outranges. If they're gonna attack, you could DD out of the way and surprise poke them, then just do whatever you feel like.2. I struggled alot when I was rushed in and comboed very badly. The only thing I could really do was really to try my best to attack but I was extremely defenceless.
What are the best options for both of my problems? Thank you!
I don't have too much MU-specific information, but hopefully that'll help.
