Between these two accounts I got some decent rewards. The two gold cards I'll hang on to instead of selling because they are so cheap. The IMP BOWMAN and PHANTOM SOILDER were a welcome sight, since they are getting pretty close to being maxed out. The most exciting card of course was the THE KRAKEN, but I still need one more to level it. The FIRE SPITTER is also a neat little Dragon card, and this drop gets it to level 3. The remaining stuff I'll just keep leveling and decide what to do with them as I go along. I started leasing some of my half upgraded cards to my alt, and have had great results with that. I think one of the virtues of having multiple accounts, is that you can use those lower level cards more effectively in the lower levels. When you've got a bunch of maxed out cards from the Beta, trying to use these cards just drags you down.
