Rajas Cards & Karma: My Favorite Mechanism

About Rajas of the Ganges: Cards & Karma, from BoardGameGeek:

In Rajas of the Ganges: Cards & Karma, you compete for coveted double-sided cards that show buildings, goods, ships, or palace actions on one side and a colored die value on the other. Always keep an eye on your opponents' actions and plans because what they would like to build could instead be useful to you as a dice card. Although perhaps you want to acquire another building yourself and increase your fame...provided you have the appropriate dice cards in your hand as a resource - or would you rather sell goods to get money? Pay attention to the 3 because if you have three cards of one type, you must swap them for workers - and while workers are multifunctional and useful, you don't always want to get rid of your cards just yet. The first player to turn over all six target cards one by one through fame or money wins.
