A Barbarin King is required for faster clean up, with or without ability but much assuring if ability is in hand. Request either Balloons or a Dragon and a Balloon for Clan Caslte, I personally prefer the 5 Balloons but either is fine. NOTE: This strategy is picky and requires Air Defenses at most level 5 close to each other without any tile spacing in between any of them.
Drop the Lightning Spells in the middle of the Air Defenses, afterwards, drop the Earthquake Spell to destroy them.
Identify which area of the base has more Archer Towers, deploy the Dragons in a line near it. Archer Towers pose a threat to Dragons and must be eliminated quickly.
Send in the Clan Castle troops when needed.
Drop the Barbarian King on the opposite part of the base where you dropped the Dragons for faster clean up.
(No execution notes)
A 3 star is guaranteed if execution is good. However if one Air Defense does survive, Balloons can clean it up but be sure to have Defenses destroyed around the Air Defense to make sure they head towards it.
