This strategy has worked for me all the time. Carefully time when to place your troops. Ideal: Place most/all of your barbs as a meat shield to protect your archers (If you like place some barbs around the area to search for bombs or traps) after your archers have been placed, put all of your giants to take out the air defence. If they are fairly damaged place a heal spell while they take out the walls guarding the air defence. After the air defence is destroyed, deploy your healers to heal your giants. After a while when you're ready place all of your balloons in a line and drop your other heal spell if they are injured (you can rage your balloons if you like if you want to speed up the attack). Drop some goblins to quickly take out the storages if your troops are slowed down by them. You can do whatever you want with your clan castle troops (I recommend having a dragon).
