Amazing! I don't see y I wont be in the next update!
Ima give you a few ideas. If accepted. The ghost at lvl 1 could have a like tansperent white look and a calm face. Lvl 2 could be the ghost getting a mad look on his face thus making him get a evil grin. Lvl 3 his eyes turn red and his arms have blood streaks. Lvl4 he gets sharp teeth and he holds little skulls in his hands. And for the revive system it could be like, let's say there are dark graves and reg.graves . The ghost comes in the area and what ever unit was there becomes a transparent ghost like figure. Like a ghostly barbarian or gaint. The ghost could be undetectable from traps and clan castle troops. The revived troops would be detectable by everything except clan caslte troops. And if some one had a ghost in there clan caslte then that ghost would revive it's fallen clan caslte troops to help defend. Just some suggestions for this amazing idea. Sorry if some of this sounds stupid😇
