User blog:EddieGLO/Need help with unit selection please!

Hey guys, so I just need some help choosing what units to use just for farming. Will most likely keep the units the same until I get a better grasp on the game. I am an older player, but never really understood the units and what they do. I'm only a level 68 right now, and whatever you guys tell me will definitely help me out, so thank you, and I'm looking foward to hearing from you guys soon! Thanks!

Guardian-Emerald Tusk Daze (Omni)- Not sure what that means, but this one isn't a 7 star I think..lol

Oracle- Turbo Wings Nemethgear

Lord- Fickle Flower Phileine

Lord- Kyo Kusanagi

Guardian- Flame Legend Vargas

Anima- Divine General Izuna

Anima- Grave Carver Aaron

6* units--

I appreciate your help, thanks again!
