Lure and kill the defending Clan Castle troops (if any) with the Archers. Use Wizards if necessary.
Attack from the side with the easiest route to the Town Hall, if trophy pushing. If farming, attack from the side with the easiest route to the Storages. Deploy 1 Giant to scout for traps, then follow it with the other 11 Giants. Deploy 2 Wall Breakers. Deploy the first Heal Spell ahead of the Giants.
Deploy the Archers and Wizards behind the Giants, and make their presence heaviest in the path of the Giants so they funnel towards the Town Hall. Also deploy your Clan Castle troops (if any) behind the Giants. The best Clan Castle troops for this attack would be Level 4+ Hogs, or Level 4+ Wizards.
When you think the Giants need some healing, deploy the Healer and the last Heal Spell immediately after one another.
(No execution notes)
A pretty good Town Hall 6-7 strategy that usually 2 stars.
