Best Attack Strategy for Th7/Th8!

I have discovered a very effective attack for lower levels. All you need is a level 9 barracks, around 170 troop space, and some healing spells. (You only need one per raid if the giants seperate) Here is the army comp:
2 healers (28 space) 1 wallbreaker (2 space, to help out the giants getting through walls) 3 dragons (60 space) 10 giants (50 space) 30 goblins (30 space, you can take out 2-4 of them for more wallbreakers if you want)

This attack, it's not as efficient as BAM/Barch, but the bases you can raid with this... I have so many 3-star 600k total resources raids it's crazy! (300k of gold/elixir usually, 1,000+ DE) If your patient to find the right base, you can 3 star it no problem. Here is how to raid:
first, send in the giants near an air defense. Use wallbreakers, and try to take out 1 or 2. Most bases around 1400 cups have only 2, but a few how low level air defenses so it won't wreck your raid. Now, once 1 or 2 air defenses are destroyed, deploy the healers. The heal spells are for if the healers get distracted and you need to aid your giants. Then send in the dragons for clean-up, and the goblins to take the resources once almost all the defenses are gone. Your giants stay alive, your dragons wreck, and your goblins ensure you steal ALL that precious loot. It's an AMAZING trophy hunting/farming hybrid attack. The only drawbacks are a heavy reliance on air troops, (which can be a plus if you take out all of the air defenses properly) and a high cost/training time. You will usually make that elixir back, and profit a lot of gold and DE. But if you are saving for a high elixir upgrade, this strategy is not ideal.

I am definently going to try it out.
