you only get the refund for like 2 week after the change , below is the article from the horse ' s mouth pal . we have 2 week Update came out 3 rd October , Full refund was stopped as of October the 17 th over a month agoThis is always how they ' ve done it they ' re not going to give you a permanent discount on any card they nerf , thats stupid . You ' re given a small window of opportunity to claw back dust you spent on crafting a card which you did so at least in part because of its power level , you therefore have the chance to claim the dust back if you feel without the previous power level it is no longer valuable enough to you to keep . It is not intended to be a permanent opportunity for anyone who pulls the thing 2 years later to go ahead and claim full dust value when they never owned the damn thing when the nerfs arrived that ' d be silly . updateoctober 3201603102016
