Best way to get Champion Scarlett Witch?

I was S0 player on Marvel Rivals played until I wanna say Season 3? I got Lord on Wanda really fast and then I stopped playing the game, I’m all the way now to level 38 and it’s taking very long to get her leveled up and I don’t know if I’m doing it the most efficient way so I wanted to hear other people’s thoughts and strategy’s for getting Wanda to Champion?
