Congratulations aubryd on those reward cards you're already upgrading! I'm following the same strategy; I'm starting to buy common reward cards and will move on to rare ones later. I started buying these reward cards very late; I was really excited about the new skins last October and ended up spending all my glints on seasonal skins😅. But it's time to get serious and start strengthening my Arcane Conclave deck. Cheers.
