Place 1 of your barbarians near the range of the clan castle. then if there is clan castle troops draw them out with your other barbs. then, once out of range and in a close range of each other drop your lightning spell on them.
Place all your giants on one of the sides of the base. Try to get a side with no to minimal splash damage. Eg 1 wizard 1 mortar and get a side with the air defense closely near the edge or outside of the walls.
place a heal spell on that wall.
drop your wall breakers amount dependant on leval of wall. LVL 2, 1 WALLB, LVL 3, 2 WALLB LVL4, 3 WALLB LVL5, 4 WALLB LVL6, 5 WALLB.
then place both of your healers on the giants.
then place your wizards in a fan behind the giants quite spaced out to clean up all the outside buildings.
(No execution notes)
If done correctly and if you dont run out of time, the least amount of stars you should get on this raid should be 2 stars. I have gained 1000+ using this attack strategy alone.
