As the game evolves new features come to steemmonsters. Though new challenge mode is not a new game mode but the most cool game future ever. With the new challenge mode you can play with your friends no matter if they play in bronze league or champion. You can choose if you want to play only with gold monsters, alpha monsters or all of them. The most interesting feature is playing for a booster pack. The person who wins the match takes the booster pack. You can also do some experiments or try new strategies with your friend or with yourself without losing rank.
