I'll probably be ripped apart for this, but here I go.

In discussion on point #2. Right now, there are a good amount of people who are working their asses off to abuse the system. But, it's not against the rules that the developer team put in place for the tournament, so they are earning these cards. It may not be by being good at triple triad, but they are putting a lot of work to one up other people who are trying to work the system as well. And while that work to the majority of the people who have a passion for the game(myself included), may seem disgusting and vile - it's still not against the rules. For the developers to completely void the efforts of the players who honestly believe they are working within the limits they were given, I can imagine that SE doesn't believe that's the right thing to do.
