On top of literally everything you already mentioned... Brawls also have 4 out of 12 Gold Card only Frays which can only increase the need for gold cards. Maybe not so much the Alpha packs specifically... but gold cards overall. Absolutely!
I had never noticed that there were Gold Level card tournaments... I definitely don't have a collection that would be any use... but man, there is SO MUCH to this game.
Thanks!
Wow, really good point. I did not look much into the Brawls yet but this will become even more relevant when the guild shop comes out.
They've honestly been really fun. I've absolutely enjoyed the coordinating with my guild.
