The Night Witch is rumored to be the next card that will come out for "Clash Royale," but a leak somehow showed that it can be unlocked through a challenge called the Insane Draft Challenge. The game is also fourth overall when it comes to 2017 first quarter mobile revenue.

According to a report from Hi-Tech Gazette, introducing new cards is one of the ways Supercell keeps people interested in playing the hit game. And the rumored next card will be the Night Witch, which is a legendary card.

The report said that the Night Witch, which can also be called the Dark Witch, targets terrestrials and provides fearsome damage with its rod. It creates bats that regenerate every two seconds and can help players easily grab the battlefield. The Night Witch is basically "a perfect blend" of air-ground attack.

The last update had revealed that the next card can be obtained through the Insane Draft Challenge. But the Night Witch is not the only reward to be obtained from the challenge, as other rewards could be acquired in winning the challenge. The rumored rewards are 100 gems, 5,000 gold, 20 dark prince cards, a Giant safe, and the Night Witch.

Details of how the challenge will go haven't been revealed yet and it's also not stated how many victories players will need to obtain the legendary card. These kinds of updates and new items are the reason why "Clash Royale" is one of the most beloved mobile games.

Venture Beat reports that Supercell's game comes in fourth overall when it comes to the worldwide revenues of mobile games in the first quarter of 2017. "Clash Royale" comes in at second when it comes to the Apple App Store, and fifth in the Google Play Store.

The report said that "Clash Royale" had surpassed the $1 billion mark in lifetime gross revenue in February 2017. The statistics come from Sensor Tower Store Intelligence and it shows that the top game overall, in terms of revenue, is "Monster Strike."

And with great new features, such as the Night Witch card, the numbers will undoubtedly continue to increase. Check out the video below for more about "Clash Royale's" latest update.
