if your playing on the cake network, they have gold gard card tournaments were you can purchase gold cards from the exchange then use them in goldcard tournaments. They are always +EV. Rite now I see they got a $200 tournament where you need five 4dcards to enter where you can buy them on the exchange for 11c each. So its aout 55c to enter the tournament. There are only 27people registered rite now and it starts in 40ms. I like to check now and then becuase sometimes they will have a tournament with huge +EV.
