This is important, you MUST check for Air Bomb. The Dragons can do a good job, just make sure they live. Without taking out the Air Bombs, the Minions will die.
If the Dragons have not taken out the outside buildings near where you want to deploy Minions, then use Clan Castle troops. This is because Minions are stupid and will attack the closest thing.
Spamming all your Minions at once may not the best idea, as Air Bombs can destroy ENITRE SWARMS in one blow. If you think it's safe, then you can use all of them. They are overpowered in swarms and the secondary Air Defense will only shoot one at a time. The Wizard Tower can be a problem depending on its level but your Dragons will make short work of it. Archer Towers may take out the Dragons, so make sure the Minions take out the Archer Towers.

That's all, people, I have so far gotten 3 stars on 4 TH8s and 2-stars on a strong TH9.
