Lol... I think I can do better (or worse depending on how you think about it) because I've had some real losers.
The second one wasent too bad. First one was horrible lol. I only buy premium packs. Havent needed to in a while though, I always hover near 100 cards in my deck at all times.
Premium Packs are extremely more worth the credits compared to standard ones. I mostly open them up for fun though.
