You will just need to somehow save up gold for the upgrade. It was very difficult for me too because I had the 25 flames. Different users get different numbers, if you're given a set there's not really much you can do. They aren't going to give you the other set even if you got it before because both sets are in the middle of testing.

Luckily, the upgrades for the 250/25 set cost 100 gold compared to the upgrades for the 50/500 set. Hopefully some of those advertisement goals can come along so that you can get a decent gold boost towards saving.
