I would do a mass dragons attack, with 3 lightning spells, and with balloons/dragon in the clan castle.
1. Lightning the Air defense next to the Dark elixir drill.
2. Deploy barbarian king in front of the level 3 mortar.
3. Deploy Clan castle loons/dragon in front of the level 3 air defense.
4. Wait for about 5 seconds.
5. Deploy a line of dragons in between the level 3 mortar and level 3 air defense.
