Silver, Gold, and anything else higher, I'm perfectly fine with doing a charity for them since they take an assload of karma. But black is only 350, and you get 60 from winning Crookies, so that's over a sixth of what you need being handed to you in one game. That's lazy as fuck, imo.
I have 2999 checks in my Casting. ONE FUCKING MORE.
Without even holding a charity. B-)
