Until you get more girls you could RG Duranta (Easter). She gives 45% Crit rate and could free up Mei and Cactus from the Dendro team.
Could RG Liatris re-action on Mei and her with Cactus is a decent offense for a second team. Would still need to get crit to 80% though.

Also the gacha for Corbett should be mid March. You could just start thinking about a team to use her. I don't have her yet, but she looks pretty good.
