Suicide Squad for farming Barrel Bull / Backstab Squad (Elite)

It works for me very well

Handsome Team

Barrel Bull = BB


Preparation:


(30 blue) Brick
(30 blue) Thief
High level Lady, high level other healer like Qriest (borrow from friend or your own)

First two rounds:
Thief Lady Healer
Brick Healer empty

Last round:
Thief Brick Lady
Healer empty empty

Rogue also works for this. I used lvl 30 blue rogue since I didnt have thief and it worked.  I'm on my way to maxing out BB so I farmed lots of BB.
