Strategies for TH 5 include a few different strats since bases start becoming too hard for CC troops to do the job.
Balloons: Using mass balloons can three star a base if heals are used correctly or the AD is close to the outside of the base. Balloons need the CC lured and killed.
Giant/Healer: Giants can destroy a base if the AD is accessible rather quickly. Wallbreakers are needed in the army and healers can help sustain giants longer.
