Select 10 of the 30 types of Common Cards included in the game. (See Recommended Card Sets for some recommended combinations of cards.) If you want to decide this randomly, shuffle the 30 Randomizer Cards and draw 10 of them. Take five of each of the selected 10 types of Common Cards, plus the two Rare Cards (Imperial Capital and Imperial Crown), shuffle them altogether, and place them face down. We call this the Supply Pile.
