By the time I started to play this game, the old players and forum administration and a group of players used to set up competitions with lower mechs with rules stablished. They can get some prices not for the general player in the normal pvp. It is a tournament and can get special items like a Goat or Unicorn perk. It is distinctive item to have and are very few around because you need to win the first place and because it is uncommon it does looks cool.
The tournament is set in a way that everyone, including you at your power level, can compete with everyone at the same plain field toe to toe and win against the best players on top position in this game not having power base advantage over you and eat their candies.
So, a group of players plus Marija part of the forum administration, they come with ideas to create a tournament and the rules plus prices. It does require to summit the build after rules are implemented by forum users only then compete against each other till the finals.
It is a cool thing to do in particular for those who can play at different hours because time zone it does affect because everyone lives in different part of the world.
