I have been at xx60 energy for about 10 levels now, and have been looking for those elusive 2 +20 energy tank cards to bump me up to an even 100 (I know, petty quibble, but it is bugging me) but all I get now are +50 and above cards. I just wanted to ask, did I miss out on my chance at those +20 cards because I am 50th level now, or will they eventually come up?
