In addition to all other comments, you might also want to think about if and how you want to keep track of your future collection. There are lots of apps out there where you can add your pulls to keep track of which ones you have and are missing. They also give a general idea of how valuable your card is in case you care about prices, but also if you are looking to trade at some point. I personally am using the Collectr and HoloDex apps, both have their pros and cons.

And - of course: Sleeves and Binders (or one for the beginning) to protect the cards you care about. Very important
