as to your question on buying individual cards, or packs of cards, I've done some of both. The main reason I have purchased individual cards is to also increase the skills more than fans so I can balance the two and reduce Ego. I also purchase individual cards so as to get cards that no longer drop from packs. With packs, it is a blind draw, but it is also better to if you get lucky for a couple of Epics, and a mix of other cards. Plus it is the best way to get the Seasonal cards used in the seasonal events.
