I'm sure that this will definitely not happen but i think that NU Lakia will be a perfect replacement for SInatraa . He is a sova main ( plays sova on ascent,bind and haven) and can play duelists like Raze ( plays raze on split) and jett(on icebox). He can even play skye occasionally . His agent pool as well as playstyle is quite similar to that of sinatraa, so he might be a good replacement for him.
