I am playing Clash of Clans since Spetember, 2016. I have used many strategies for war and have shared one of my favourite war strategies (TH9). I don't remember to fail an attack using this strategy. Its pretty easy to master and you can three star a TH9 with this strategy.
3-4 Wall Breakers
18-20 Hog Riders
1/2 Baby Dragons (For funneling purposes; in case if there are ground defences)
1 Jump (or a healing spell depends on base)
5 bowlers in CC and poison/freeze
Plan and Execution:
There are 3 main steps to use this army.
1. Making funnel for bowlers using Golems and Wizards/Baby Drags
2. Deploying Heroes and Bowlers to kill defensive heroes and Clan Castle troops
3. Deploying Hog riders to destroy rest of the buildings.
(NOTE: Always save 2-4 wizards for clean up purpose at the end of the attack when defences are down).
