Make a new labotary which does not upgrade but it changes the troops of break to evil troops . for example if we change barbarian into evil barbarian it gets more health more atteck and more speed it is like a updrad but a different one and to optain that evil labotary, it will take 100 gems and labotary's health and function will be like other labatory and evil troop's outfit will be blooby and evil on.
