Hey, i just looked into your island. I dont know how long you've been playing but i think you are a new player. Eventhough you are on lv 45 but i dont see many epic dragon. I assume that you bought lots of gold to speed breeding( ha, just like me).Hearing that you've sold many rare and super rare dragons is truly sad. At least you should trade it for gems but not sell it.
Btw: about the contest, i dont think you can get enough food to evolve your elf. It take around 40k food to feed from lv 1 to lv 10 and the chance of winning is ... Ehm ... So just forget the contest
