We've expanded the ELO rules page (http://www.urban-rivals.com/game/rules.php?show=elo) so that the instructions are a bit more clear and and added an ELO calculator so you can see what the results of a battle with a particular opponent would be. Have fun -Pumpkin
Buying back from kate goes against the idea of "Collector Card Game". You have to choose which cards to sell or buy by keeping in mind their possible futures.
Why the hell would you sell Kenny to Kate i used to sell cards to Kate becuse i had a double and it was Cassio and know i know she going to be a cr i wish i never sold it to her i made the same mistake as you
