i mean how many unit more or less you will need kill for it????
I'm a free player and only on nutaku and it seems good to me. I can get 80 RC with just extra copies that I don't need. If I were to sell all gold units I don't use (which I won't) it would be 220. If you sell event units on farm missions that you don't want/need you can get more. 150 RCs from a farm event should be easy if you aren't trying to max the unit.

Just slowly save them up with an extra gold here and there and maybe some farm plats and you will eventually get there, maybe even before getting a black.
