Mage Company is in their final couple days for Raid & Trade up on Kickstarter. They’ve posted the rules for the game (still a bit in the raw state) on their page for you to check out.
From the campaign:
The rules of Raid & Trade are finally online. This should be good enough to get an idea of the game. This is not the final rulebook and it will be professionally edited and re-written before it is released. You can see now how it will look like, the set-up, main rules, examples. etc.
