Deploy 10-12 balloons at depending on how many you have and the number of air defences.
<Optional> Bust out a Healing Spell for healing and a Rage Spell for extra speed and damage. Use whenever necessary. Use Lightning Spell to destroy any Clan Castle Reinforcements such as Archers and Wizards. (Any dragons or minions and your Balloons are stuffed).
When almost all Air Defences are destroyed (1 left), send in 2 dragons to attack that one Air Defence while your remaining Balloons demolish the rest of the defences.
Deploy Barbarian King to finish off any buildings around the edges of the map so you can three-star it in time.
REJOICE!!!!!!! (And retrain your troops)
(No execution notes)
WARNING: This army combo is extremely good and I almost always get 3-stars. BUT! This is only good for raiding gold and trophies. Elixir is a huge waste as for TH7 it almost cost 200K to prepare it. Also takes about 1hr 30 min to finish training. During raid, also be careful of Air Bombs, Seeking Air Mines and The Archer Queen.
