User blog:BFBooster/Still a noob

So I recently posted a blog regarding my units and asked for help, i want to do the same here and I think i've improved a bit since my last post. Help me build a squad that is generally good for everything, a squad for specifics(raids, trials, etc.) and help me decide who to throw if any and who to evolve asap. I have very limited unit slots.

Here are my units so far(I wont include the typing)

7*

Ruby, bestie, avant(dandelga), tazer, luly, dolk, rahgan, ultor(blades), haile, elimo, deimos(forgebreaker)

6*

Tora, mahalu, cardes, maxwell, ronel

5*

Quartz, shera, reis, charis, semira, duran, grahdens, ark, lune, rugrow

4*

karl, zergel, aurelia

Any insights would be grealty appreciated! :D Merry christmas to all!
