If you are higher level, and this doesn't work. Depending on your problem, you'll have to adjust the composition.
(No execution intro)
Lure the clan castle troops and barbarian king out with mainly barbs. Then, kill them with a few barbs, archers, and your minions.
Pick your attacking spot. You'll best know this spot after you read the rest of the rules. Try to pick a spot that doesn't have too many walls between you and the storages, and that doesn't have wizard towers. Try to spread the archers out a bit. Not too much though, just over the area that you want the Gold and elixir from.
Drop giants. Use the wallbreakers intelligently, don't hold down. Try to save some if possible. These are the most expensive part of the composition. The goal is to completely open a path for the goblins to get to the storages
Spread out goblins if possible and attack the storages.
Try to pick a base that doesn't have wizard towers guarding its storages and that has most of its storages in 1 pocket
Hope it works!! PM me if you have any problems!!!!
