We didn't know the value of our cards which led us to some bad trades. We were also not very organized and we had to constantly go back and check our pile of cards before finalizing a deal which not only wasted time but also gave the opposition more time to think about the deal and whether or not it was the best for them. It also looked very unprofessional and made it seem like we didn't know what we were doing, which was not true.
I mostly did the negotiations and Noshin sorted out all our cards and told me which ones we needed. We were both good at knowing what we wanted and knowing our limits on how much we could offer. There were many deals that fell through because other groups thought that they could convince us to pay more but we stood our ground and walked away to let them know when we say "final offer" we mean it. This helped us later on and people took us a little more seriously. We also kept a close watch on the time and cashed in all of our cards before the time limit. Some groups didn't cash them in before the bell and lost a lot of potential profit.
Next time I would alter our strategy so that we took a little more time figuring out the value of our cards and organizing them. I would also make deals for cards with money because everyone was trading card for card and didn't know the dollar value of what they were trading. Overall it was a fun challenge and I learned a lot about negotiating.
