I'm really new and need some advise😭🙏

Hi so as the title states I'm pretty new to the game (level 30) and want some advise

Currently I'm running Scarlet witch (<3) Vision Visions daughter Dr strang And gambit I'm trying to design this team around Wanda but I'm not sure who else to shoot for and what to add. I wanted quick silver but he's not even in the question until level 60. Any advise would be huge!
