before the three elites' pull rate was reduced, they werent exactly rare cards. if you pull em often enough, at some point, your definition of "junk" becomes far more different than other people's. even now, the elites are the only 3 cards i DONT sacrifice to enhancing. if you pull em faster than you can sell em at even half price, you tend to see less value in them. :/

and yeah. i emailed bout that archangel. devs said they couldnt do anything about it.. freaking sucks. but, in case you were ever wondering, an ultra rare will max a common in one shot. :D
