Maybe adding to your pledge like $25 to $50 or based on the cost of reprinting First deck. Since I have no idea what the print costs are or how many you'd have to print to be feasible or how many you think we would be able to get rid of in the Kickstarter, so "it depends" is always the answer.
Lets use the $50 pledge increase, and you can print just 100 and think the Kickstarter would use those up, then the cost of would need to be less than you would collect with extra pledge money. In this case you'd get $5,000, so printing needs to cost less to be worth your while. Lots of assumptions in that example.
