Elemental: A Trick-Taking Partnership Game

From BoardGameGeek:

Elemental is a variation of a traditional trick-taking game. The Elemental deck consists of 4 suits, 10 cards in each suit. Each partnership has a deck of 8 Bonus cards. Players are dealt a hand of 10 Elemental cards and 4 Bonus cards. After looking at their cards, players pass 1 card to each other player; then, discard 1 Bonus card. Elemental cards must be led and are the only cards that can take tricks. Bonus cards can be played in a trick to score points, but they will never win a trick. At the end of the hand, in addition to the points earned from scoring the Bonus cards, each trick taken is worth 1 point, and each Bonus card taken is worth 1 point. After 4 hands, high score wins. -description from the designer
