I really want mibibyu but some anons say that she may rerun soon and I need to save up rolls....

what should I do? save 60 rolls I got now, roll for yi xuans engine or try astra? I'm new and now I got a team with yi, m6 pulchra and panda and in the end I want to have 2 teams with yixuan and cute miyabi
