First off, find the clan castle and place one barbarian in range of it to lure out any troops. If there are no troops, carry on to step two. If there are troops, lure them out of the base and take them out with your barbarians, archers, wizards, or any troops that you have received from your clan. Try using the smallest amount of troops you can use while taking out the enemy clan castle troops.
Find all the air defenses in the base. If you find one air defense, you could be lucky. If there are two protected air defenses, it might be a bit of a challenge. Find the air defense that's least protected. Then deploy all your giants near it, and maybe you could place a rage spell and/or a healing spell on them. Once they take out the first air defense, deploy both your healers behind your giants. Let your giants take out the rest of the defensive buildings.
Deploy some wizards and archers to back up your giants. Place some barbarians (and maybe a barbarian king, if you have one) to take care of the rest of the buildings.
Once the other air defense has taken out both your healers, place a healing spell on your giants (if you still have it, and if the giants' health are going low). If you still have a rage spell left, wait for your giants to get in an area with multiple defensive buildings all in one spot, if possible, then place your rage spell there. If you have any remaining troops, you may deploy them to take out the rest of the buildings, if you want to.
