I got 3 reward cards today. Wood Nymph, Undead minotaur and creeping ooze. Wood nymph is a really useful earth card that I will keep long term. Creeping ooze is a must have for 1 manna. I don't really use death alot and when I do I dont use undead minotaur but for only $0.01 selling I think I will have to keep hold of it.
Currently for sale for $50 is the earth alpha summoner card at max level. I have a while to go before I can afford it. I don't really wanna sell my legendary cars until i'm sure I can afford it.
