How can I play a 2v2 match in Clash Royale?

To play a 2v2 match in Clash Royale, open the game on your device and tap on the '2v2' button on the battle tab. This will present the option to either join a random 2v2 match or to team up with a friend. If choosing to play with a friend, you can select a friend from your friends list or clan members who are online. Once your teammate is ready, either by having been matched randomly or having accepted your invitation, the game will start searching for another pair of players to match you against. When two opponents are found, the 2v2 battle begins, and each team works together using their chosen cards and strategies to destroy the opposing team's towers and claim victory.
