I really believe dra is your best option here. Get 5 balloon 6 on CC would help. Make your way for the dragon go into the middle and rage them in the middle. Use their CC & heroes if it's in the center as well. I actually find it's easier to 3* a base with all 3 centralize AD because once the Dragon get there, you win. I was more afraid of 2 Centralize AD, and another one is center, but NOT that center. That 3rd AD usually the thing that prevent the 3*.
