I know about the new shuffle system, its based on random number generating. When you click the shuffle button, that triggers generating a number then stored on dragoncity server. So no matter how you choose, what you choose, the result is only based on that number. So the reward you get is already determined before you event choose a card.

And I think they're confident enough about the new system to put gem back into the daily shuffle :)
