It might be a little too early to be running stats on the Winds of Change promo set obtained through Orbs that cost 2,500 DEC, but I thought I would post some numbers from yesterday. One stat line that will be a little off is the gold cards opened and burned. Some early gold cards have a different XP than later ones, and it slightly affects the numbers. A level 4 1BCX Gold Molton Ogre might have 200XP or 250XP for instance.
Regardless here are the totals of opened and burned per 1 card BCX and not combined! Also I've added some percentages and some projections once all 200k orbs are opened. Winds of Change adds 1M total cards spread over 12 unique cards, 4 common, 3 rare, 2 epic, and 3 legendary. I did not include the Archmage Arius card, as I'm not certain it is part of the 1M total. Thank you!
