Finish Stag Knight since you're almost there, then I'd probably go with Rae. She's pretty phenomenal. Frozen Banshee is also a good bet, specifically for CB and Dragon.

rae

Gracias, I'm just having a hard time cause I have 4-5 I really want to raise and dont have the resources to do it.

I  would  definitely  recommend  Rae!  Some  other  great  picks  could  be  Steelskull,  Shamael  and  Seeker!  

Kind  regards,

BENZOBOY

Thanks 

maybe you are looking for a fancy answer, but it is hard to find someone who has more five star uses than Athel. Check Ayumilove.

It is a chore but I put all the ayumilove ratings of my champs in a spreadsheet (just the 3,4,5 stars). Then when I want a team for a certain purpose I can sort my champs say, for Dragon, or Magic Keep, and see my choices.  I keep their names in color for affinity. So if I need a red champ I can see those.

This is real handy where the affinities keep changing.

You can also do this with the in game ratings, which are somewhat different.

Rae. Nuker, CC, and debuffer. Hits hard and 33 speed aura in dungeons. Oh, and a1, a2, and a3 AOE.......If u can't gear her with good enough savage and cruel gear you could build with high ACC and a stun set to maximize CC alongside her a3 freeze ability. Just my 2 cents since I have her on my account.
