hey guys, im in the game for around 3 months now, and i really neglected the clan boss area so i need some help from you :)

so my current team is:

valkyrie, apothecary, stag knight, elenril and trunda(i know she isn't a CB champion)

so the main problem is that i dont have any poisoner lvl 60, and for now valkyrie is really helping eleneril doing a lot of damage bcs of the HP burn on the A1.

so which champion should i 6 star for CB?
i got aothar, juliana, kael and also not a poisoner but still good for CB is sandlashed survivor that are all 5 star or less

my clan is pretty week so i can only fight on hard difficulity.. doing average of 20M damage there

appreciate your help guys!
