This card is one of the best performing card among other common reward cards because people use this card frequently. I myself use this card a lot when I have free mana space left. At the moment this card is trading at 5 cents which is a good price for a reward card but I don't think price will stay like that because it is a common reward card and common reward cards always have strong selling pressure. The reason why this card is expensive than others is that creeping oze has lots of utilities. The downside of using this card is that when I use it enemy snipers take down this card first.
