avant for raids and fh, rahgan for arena lead, ultor could be a substitute lead for raids

elimo and bestie to 7* ASAP, so you can tackle hard content easier (these two should be a staple picks for your hard content squad for now). and then add griff and mahalu for raiding purpose (6* is fine, also since there's SHS currently going on just sbb10 them in their 6*). those units should be alright for your current cost

for arena team, since your rahgan is already at its 7* form, any 6* and up should be fine
