Using lucky patcher latest version (latest version as of 11/12/2014) and the latest version of both etherlords and play store, I used lucky patchers lvl emulation, and inapp emulation to hack one purchase from the shop (the pack that is featured on the main page) however upon trying to make further purchases with the emulation hack I get an error saying network connection error and have not been able to make further purchases, so you can hack one single purchase if you are bothered and lucky xD if anyone finds a way to hack more purchases id apriciate it
