Im at medium leveled th8 [Gold 3], and I found the army I use really effective, I saw people using Barcher and now since its a weaker strategy I decided to post it. I use
(all level 5 except wallbreaker and 200 army space)
12 Giants
100 Archers
6 Wallbreakers
28 Goblins
In total its around 70k and only takes 22 minutes to train between all barracks evenly. With the army I usualy easily get into the storages and 50% bases at my farming range. Basicly I use a few troops to check for traps and then make a line of giants then archers, they do most of the damage but wallbreakers and goblins really helps with the storages.
I would post a picture of my attack log but Im doing this on PC. Eitherway I still fill up my storages with frequent raids and always have a builder and labatory busy.
