If I may make a suggestion regarding card packs. You know how we need to win multiple duels in order to earn enough points just to even get a pack, and more for a structure deck? Well, how about either getting a pack per win (or saving 10 points per duel so you can use 30 to buy a structure deck) and winning just a few random cards per loss? Y'know, kinda like how we're doing with the Tag Duels right now?

I don't really like the thought of having to spend so much time and effort just for an uncertain "reward" from a single card pack. We'd be stuck with very little ability to upgrade our decks.
