For the past couple of weeks I was unsure as to what I will do with the remainder of my gold foil and legendary potions. But now I have made my decision. Because opening packs is fun I will want to do that whenever I get the opportunity to do so.
This means that I will just pump all my DEC into the card packs as soon as I have received enough to exchange for a single pack. As I am still actively leveling my BETA cards I think that will be the packs I want to upgrade for now.
And as the UNTAMED set hits the market I will probably just switch to that set and try and level that as much as I can afterwards. I hope this way of leveling allows me to collect a whole bunch of DEC and allow me to go beyond the gold league in which I am stuck now
