Not sure what to flair this post, but here it goes. I'm new to the hobby and, after playing Arena a fair bit, decided to buy some card packs. Tonight, I was opening some out of a Zendikar Rising gift box when I came across something I didn't expect. I found a Drana, the Last Bloodchief card with a gold foil stamped date on it. I quickly found out that the card was a prerelease card.
Does that kind of card typically make its way into a draft booster pack or did I just stumble upon a nearly impossible find?
