Too many yellows! Now what?

I just did a 40 draw for Avalon and was rewarded with the following 5*’s

Vivica
Joon
Justice

I also have a fully maxed Poseidon and a Rana at 3/70.

I’m one dart away from ascending my second yellow. Any suggestions on who to use them on? I was thinking rana but now I have all these others.

The rest of my maxed heroes include:
Ariel
Seshat
Proteus
Merlin
G. Falcon
Boss wolf (3/70)
Kadilen (3/70)
Grimm
Magni (3/70)
Boldtusk
Melendor
Wilbur
Hu Tao

I’m also sitting on Elena, Obakan, the new hotm, and master lepus but don’t plan on leveling any of them.

Imo, go with Joon because you already have the best healer in Ariel. Justice can be after Joon is done.

I was worried joon and Poseidon filled the same role but one can never have too many snipers I supposed.
