there are rumors circulating that the SPS staking in game or having the right amount of SPS in your account will qualify certain accounts for earlier access to the new packs. though that's just a rumor from what I can tell, however the rewards cards will be released next according to their Mailing service Gold foil press. This was suppose to take place following Guild brawls 2 recently released so for the money honestly the quest potions are the bet bet though I have gotten nothing in a week.

Since you have an account power of 100,000 or more you can get I believe 10 or 11 reward chests, though the odds suck and its now much more expensive its still worth it in my book where as the packs seem like a higher probability of a loss at this point. Besides with the quest potion shooting up in price so did the reward cards prices or they are I should say.
