I meant you should play regular matches (the ones that you start from the Battle screen with the big "Battle" button). Grand challenge and regular challenge use the same pool of players (you can be matched against someone playing grand challenge while playing the regular challenge). That way, you are playing against the average player. Plus, regular matches are free and typically result in better rewards.
