The army composition can be made at town hall 7, but it can be quite expensive, and at th9-10 other attack strategies open up to you because of Witches and Lava Hounds, so this attack strategy is usually better for someone who is town hall 8. The levels I put for the troops are recommended, but a level below the recommended level should be fine.

Minimum Troop Housing Space Required: 200 Minimum Spell Housing Space Required: (not specified)
Lure out clan castle troops with your own clan castle troops/heroes, archers and minions, and proceed by clearing out the buildings outside with your clan castle troops/heroes.
Deploy Giants as a distraction, while you deploy Hog riders to destroy an air defense, or two.
If you brought 3 Lightning spells instead of 3 Rage spells, destroy another air defense. If not, go straight into first deploying your dragons as shields, slightly apart from each other. Balloons follow up and use any remaining troops to snipe a builder hut in the corner.
Deploy 1 or 2 rage spells as your troops draw close to the town hall, 1 for your dragons and another for the balloons to destroy defenses faster.
You may use the last rage spell if you are running low on time to speed your troops up.
Usually a 2 star, possibly a 3 depending on the base.
