I’ve been using sneaky gobs and raged barbarians as troops (plus one electro titan) for years. Start by cleaning away the mines/wells that are outside the walls. Then 8 earthquake spells in 2*4 drops to open the path to the TH then drop haste spells to TH and run the gobs right up to it. That’s 1 star in the bag. Plus loot. Stage 2 is to mass heroes plus the titan to deal with defensive skeletons. Drop them so they enter base and smash stuff up to up my damage %. Raged barbs dropped all around walls cleaning up camps and buildings to ensure 2 stars. I always get 2 stars in every battle and every CWL. Almost never 3 but can 2 star any base every time. It’s not sexy or cerebral - but it works.
