A few Qs...

1. Why would it cost $200K to do this?
2. Why don't you just sell the $100K of prizes to fund it
3. Why don't you just sell the cards like your alternative, and then burn the proceeds, which seems to amount to the same thing. You can even take "$200k" first then burn the surplus
4. Why not just give the cards away for free to long term players who have played X amount of games? getting free stuff is actually good marketing to get new players. The constant drain and never-ending selling this game presents is a huge turn off.
