Legendary Cards are looking well balanced in regular play, though, so we didn't want to lower their strengths in general. Instead, we're planning to bump up the Tournament Rules level of epics, rares and commons to bring a better overall balance to Tournament Rules gameplay. The new and improved Tournament Rules will look as follows:
To help players get to the Tournament Rules more quickly, and considering that we're planning to increase the levels in the next update, we wanted to bring two cool new things at the same time!
Firstly, we're going to DOUBLE the rewards inside every Crown Chest. This will make grinding out those Crowns and unlocking your dAIly Crown Chest even more worthwhile - twice as much, in fact!
Secondly, we're revamping the card donation and request system so that it improves as you reach higher Arenas. For example, in the Royal Arena you'll be able to request 30 Common Cards or 3 Rare Cards at a time!
All of the changes above are coming with the next update - current ETA is early next month.
