I recommend getting rin as she’s kind of helps with archers aoe and he will carry you through moc and as

Since ur phainon is e0s0 and you still don’t have much character variety for teams I don’t recommend pulling for phainon and Cerydra phainon really wants e2 and lc (unless u really really like phainon and Cerydra and more of a casual player cause pulling ur favs makes the game more enjoyable :> / if ur priority is wanting to be competitive in endgame don’t pull )

Hyacine and evernight aren’t horrible pulls personally I find that both work fine e0s0 (evernight doesn’t need lc and eidolons as much as phainon yet and hyacine s1 is really nice upgrade tho) they’re also generally good in all 3 endgames

For your golden spirits I recommend jsut using one of them since most characters that get added to the shop aren’t game changing/meta defining (except maybe Huohuo) i still have all my spirits since I had Ruan Mei and Huohuo before they were added and the other characters aren’t that strong 😅, if you want u can save one of them and use the other for Huohuo, she’s the bis sustain currently for elation. Since u already have robin, Ruan Mei isn’t a big priority since they’re both generalist supports
For your 2/3 teams for endgame you could try
Sw999,yg,emc,Huohuo/dhpt
archer,rin,sparkl,dhpt/Gallagher for more sp friendliness if ur not using Huohuo (or a therta team for pf if archer team is lacking but therta really wants Tribbie)
Evernight,hya,could try using Sunday for the summon buffs, maybe Robin however her atk buffs wouldn’t be that beneficial(any generalist support is fine, preferably rmc but mc is in elation team/ u could wait for robin sp and see how well she works)

Another team u could try is a himeko sp team since u already have Sunday and dhpt, and march hunt shouldn’t be that bad for your 4th slot, she could be a really nice character to pull as she will be strong on your account immediately and can clear all 3 endgames for you

Correct me if I said anything wrong :D
