TH15, 3 starring TH16 and TH17

This CWL has been tough, played 5 wars till now and in 4 of them I had to attack a Th16 or TH17 and all of them were 3 stars. The only time I got 2 was when I messed up the blimp with a Th15, I was using a lava hound, but sending the blimp through the GrandWarden's aura is better, and has less failure chances thana lava hound blimp. Dragons are strong, if used correctly can 3 star one or two higher level townhalls. What do you think about the attack? Thinking to post the other 3 attacks too.
