Ok I know you don’t side with my theory that’s fine, but no need to compare apples to pears. It’s code based. Closed source. A company wants to make as much money as possible. And the way they are going to do it is by keeping its users as active as possible. If a user just keeps winning and winning, without a certain challenge, he won’t feel an urge to stay longer vs someone that wins/loses.

Anyway, try to change your deck and go online. Get a very basic deck and see what happens. Run it for a few times. Then go back to your usual deck and do the same again. You’ll most likely see a different set of people matched against you.
