What's the logical and best course of action to improve my Mydei team?

Just to preface, i really love Mydei but out of all the teams I have (his team needs the most work cause he doesnt really get shilled and he finishes in more cycles than my other teams)

My Mydei team is: E0S1 Mydei, E0 Tribbie, E0S1 Hyacine, Flex

Flex being Sunday but he's been occupied with my E2S1 Phainon since esp with Cerydra coming then their synergy is even more pronounced

My Sparkle is occupied with Archer. So there's only RMC

My Archer team, Break premium, and Phainon teams can clear in 0-1 cycles but my Mydei team suffers.

I really want to know what to do in preparation for his rerun.. is it worth rolling for E2S1 Mydei but doesnt that have anti synergy with Hyacine? Do I hope Cyrene synergizes with Mydei? Do I go for E1 Hyacine? I miss using him but the lack of dedicated supports really hurt that I dont know whether to just jump ship and roll E0S1 Anaxa or try investing diagonally to Mydei?

Thanks!
