This promo card can be added to the thirsty customers deck. Doc Francis there loves Sarsparilla, which matches the “DMML” recipe in the base game -- the one with the scored out “perfect.” He also will pay an extra $2 for any beer that is sweet. (He's offering the ORE-SOME style dollars, but we'll give him a 1 for 1 exchange rate because we're generous that way.) Now mechanically speaking, Sarsparilla makes DMML slightly more valuable than it should be, so it’s not recommended in highly competitive play but it was just meant to be a fun little reference to our first game, ORE-SOME that we hope you enjoy. —description from the publisher Included with Kickstarter pledge rewards.
