Disheartened by the grievous rework? Never fear... BB8 makes the team amazing!

Managed to beat 2 revans with gg, b1, b2, bb8, r2.

First dont use ID with bb8 just normal attack, then smoke on r2, and then try to survive :). R2 of course gets marked and dies pretty quickly. ID does not fire cause bb8 dies afterwards, but nevertheless GG strikes pretty strong in future turns.

So it's tricky but doable. Don't have droideka geared up.
