Clash Royale 1.9 update rolling out with four new cards, 2vs2 modes, more deck slots
Four new cards will be added: Mega Knight (legendary), Cannon Cart (epic), Flying Machine (rare), and Skeleton Barrel (common). According to Supercell, each of these new cards will launch with a Special Challenge. Speaking of which, new Challenges will be available in the latest version of Clash Royale: Sudden Death, Ramp Up, and Triple Elixir.
Another valuable addition to the game are the new 2v2 game modes: 2v2 Friendly Battle, 2v2 Draft, and 2v2 Challenge. The developers also promise to allow players to collect chests with their friends in a 2v2 Battle.
Basically, after the update, a “2v2” button will show up in your game. Use the button to invite a friend, Clanmate or pair up with a random player to play a 2v2 Battle for chests, Victory Gold and earn Crowns for your Clan Chest and Crown Chest.
