Brave Frontier

Farlon is an arena unit. If you really wanna replace units, replace Farlon, Kikuri and Sefia (in that order).

That's what I've been planning to do, but Sefia is my waifu. Simply can't
Anyway, this little dude is the one I want to swap for Kikuri whenever we get this batch to 6*, I mean just look at him just with a standard sphere he's already hittin as much as Kikuri! powercreep at its finest

As for my other units;

This pretty much covers all the relevant units.
Keep in mind that I'm a F2P.
This is what I'll try to do as soon as I finish my rainbow team.
I want to make an Arena team consisting with.
Leviathan -> Felneus (L) (Leader) (Still got to work a lot for this)
Ophelia (6* already) (A)
Farlon (already stated)
Grybe (5* and ready to hit 6*) (O)
And probably Dilma or Alyut.
I still will try to get a Luther when he gets his rate up (been saving a couple of tickets).
