Bring a level 5 (max) golem and an earthquake spell of any level in your clan castle. Make sure your heroes are at least level 15 (depending on the strength of the enemy base, my heroes are level 20 and 16).

There are two main parts to this attack. The first is the rush of the golems, wizards, and heroes. The second is the hogs attacking the defenses from the back.
Before attacking, you need to locate the archer queen and look at the clan castle radius. Your goal is, using the earthquake spells, golems, wall breakers, wizards, and heroes, to kill the queen and the clan castle troops because those pose a major threat to your hog riders (and pretty much everything else). Also, look for possible double giant bomb locations, as this will affect your hog placement.
First, drop the four earthquake spells to destroy walls that will allow easy access to the queen and the clan castle troops. Deploy your golems to tank and back them up with about 6 wizards, creating a funnel for your heroes and remaining wizards (drop wall breakers to break the walls). If everything is done correctly, your force should be making its way to the queen and the clan castle troops.
When your heroes only have about a third of their health remaining, use their abilities. Soon the queen, clan castle troops, and some of the core should be destroyed, with at least one golem still intact and wizards still alive.
Now it's time for the second part of the attack, the hog rush. You'll need to deploy your hogs in a manner that they won't trip any double giant bombs. It's difficult for me to explain exactly how to do this. You'll use your three heal spells for healing your hogs. Make sure your hogs destroy defenses in a way that they "meet up" with each other.
If everything is done correctly, the hogs should have destroyed all remaining defenses and some should still be alive for clean up. Use the 5 goblins to aid in damage, as they more damage to resource buildings.

If the funnel for the heroes, golems, and wizards is properly made and the hogs are properly deployed and healed, you should enjoy your three stars! Leave a comment if anything doesn't seem clear to you and I'll do my best to answer it.
