If using Healer, deploy the barbarian and lure out the CC troops. Then use the archers to destroy them. Then, deploy the Wall Breakers on 1 wall (closer to Air Defense if using Healer)
Deploy Giants (and Healer/Dragon)
If using Barbarian King (town hall 7 and 8), deploy it, and straight after deploy Wizards in a line. Wait for the wall to be destroyed, use Iron Fist (barbarian king level 5 plus) to get more troops and wreck havoc!
Deploy Minions/Hog Riders.
When Giants have low health, use the Healing Spell to heal them and use the Rage Spell to make them better.
Use the remaining Archers to take out the weaker buildings. BOOM!
(No execution notes)
This is a recommended attack strategy for WAR. Using it during normal attacking will waste your time and Elixir.
