Nice to have met you at GenCon... Just sitting down for our first game... We find a reference to a max hand size of nine, but no reference to how many cards you start with or how you draw/acquire cards to play. Looking forward to getting started! Thanks.
As the "Setup Rules" in page two say: All players start with ALL the nine (Kingdom Tile) cards of their selected color.
So, if you get the red dwarfs, you get the 9 red Kingdom cards in your hands.
We hope you enjoyed Gen Con, and we wish you happy game time :)
