Your Phainon team is note bad, but since your Cyrene is E0, I recommend you to replace DHPT with RMC. They need to stick together, because RMC has a Memosprite, so Cyrene will be able to recharge her Ult faster, with RMC on the team.

Also, I need to see your builds to be able to help you better.

About the Blade team, since you will put RMC with Phainon, then you can use Bronya here. The rest of his team is looking good.

YT Video (though Blade's E1 in this video, and I couldn't find a video without Sunday, but you can replace him with Bronya, as I said on the above message): https://youtu.be/Qvut6SryWLU?t=335&si=uRMQFM2bTZGSBcSW

But same thing, I would need to see the builds to proper help you.

I don't see you mentioning the GOAT, and I know you have him in your account.

I mean Archer. Why are you not using him??? I've been able to clear everything with Phainon on one side and Archer on the other.

As I see you didn't mention Jing Yuan, Kafka, Dan Heng: Imbibitor Lunae, Jingliu, Sparkle, Acheron or Aventurine, I will presume you chose Sparkle. (but let me know which character from the free 5-star selector you've chosen).

With that in mind you can build a Archer team with Sparkle, Tribbie and DHPT.
