Hi Gozine1, Earth Maiden do appear in level 3+ guild shop. I'm sorry but we cannot disclose the exact appear rate. Its appear rate is the same as that of the great 4 star cards such as Stheno (the lower version of Medusa) and a little lower than that of the less great 4 star cards (such as Fencer).
Enjoy the game!
