So in MoC should I as a beginner trying to run through the floors in 2 separate ways? If I do them with say 2 sustains then I guarantee the 1 star for never dying, then I can repeat for the other 2 stars? Does it work like that?

Is Cerydra a good Sunday LC user? What about Bronya or Trib? I only know that Sparkle is good at it. Just wondering if I should go for a 2nd Sunday LC and if its good for my account
