guys i have some ideas, The skelleton cow/ famined cow which every time it attacks it gives the unit behind a milk (milk gives 1/1 and is a tier 4, the second unit im thinking of is the kiddo is like a skelly with a those kid hat's its abilty is everytime it drinks milk it gains +1 health. Its a tier 1 skeleton and another one "the egg", its a tier three unit and it takes three turns for it to hatch. the egg does nothing, it consumes one coin per turn at any level and has no stats, once it hatches it becomes a dragon that has alot of stats (stats depending on level ofc) and its abilty is at lvl 1 it starts with the magic effect like the wizard's magic effect, at lvl 2 it starts with the magic effect and gains another one every time an enemy dies (can only do this a max of 3 times) and at lvl 3 it gains another one every move. (you cant merge an egg with a dragon only a dragon with a dragon or egg with egg)
