ok, so the caravan master needs help. He is taking rare artifacts from place to place. He has been raided by various monsters and half-bloods. He wants to hire you to help.
You select a route. Its a number of days. You build a deck to survive that many days. 2, 3, 5, 7 or 11. Your deck has to survive that long to get rewards. You get rewards of electrum or rares depending on how long you are gone.
You do not have access to these cards while you send them on caravan duty.
2 days = 200 electrum
3 days = 200 electrum and random rare
5 days = 500 electrum and 2 random rares
7 days = 500 electrum and a rare of your choice
11 days = 500 electrum and a rare of your choice and 2 random rares.
