My current Phainon team is:

E2S1 Phainon, E0S0 Cyrene, E0S0 Cerydra and RMC

Im planning to invest more on his team next patch, so what should be a priority? Getting more eidolons on Phainon or going for E2 Cyrene (and possibly E1 Cerydra in the future)? If i get E2 Cyrene, should i replace RMC with E0S1 Ruan Mei, E1S1 Robin (currently my only two options) or not replace him at all?

Thanks in advance :)
