Barbarian King, and Healers Are recommended, but not needed.
(No execution intro)
Deploy Giants near the Clan Castle. These will be used as your Meat Shields.
To keep these Giants alive early, Use Wall Breakers so Giants won't take too much damage too quickly. Also, use your first heal spell on the Giants.
Once your Giants are in the base, put your wizards behind them. They will attack Resources Or Defenses around the Bases' First Layer or on the outside. If your Giants lose about a quarter of their health, Heal Spell them again.
Use your archers around the outside of the base. Make sure their spread out to avoid Splash Damage.
Use any Extra Clan Castle troops or leftover Archers to Attack the King and Queen, If there is.
