Super Dragon Spam to Bats

Attack from the side where you get the earliest access to the wizard towers, multi-infernos and the gigatesla/townhall, since those are the biggest threats to bats. Start with queen to create the other side of the funnel. Try to snipe airsweepers with the giant arrow. Personally I like to use the healer puppet to keep her alive longer to help with clean up, but you can change it. For the other side of the funnel, deploy the barbarian king. Use the ability immediately to speed things up. Use whatever equipment on the king as you want, but I recommend using the spiky ball, because it can get some value from defences and it gets the funnel done quickly. You can also use one of your super dragons to help the king with the funnel, but in most cases it's not necessary. After the funnels are done, deploy the super dragons in a line, with the stone slammer and grand warden behind them. Use the warden ability when needed, usually in the core or when the dps is the highest, for example around single target infernos. Use the rage spells to speed things up. After the dragons have cleared most of the base and splash damage defences, drop all of the bat spells in a corner to help with the remaining buildings. Use the freeze spells on remaining splash damage defences whenever they start targeting the bats. I got through th12 using this strategy with a breeze. I hope this helped even a single person.
