Team Leagues

The team leagues are a feature of Scrap Clicker 2's Teams 2.0 added in 3.5. They give magnets at the end of the week based on the team's efforts, however their boost was negligible until update 10.9, which buffed them massively and added 3 new leagues.

They also exist in ScrapTD.

League Rewards
Every week, teams automatically run leagues in which its members' merges are tallied and Magnets awarded to all team members who merged during that season; a team with a higher quantity of merges will award its members more Magnets as shown in the table below:

x1.1 Increases
At the following Star milestones, players' Magnets received from the weekly league are multiplied by x1.1:

In ScrapTD
On the third of November 2018 the Team Leagues got leaked for ScrapTD and on the same day the update 1.0 including them released. They run from Monday to Sunday like in Scrap Clicker 2, but instead of magnets they give Bricks and instead of merging, Wins are needed. They give 300-3000 bricks, which increase for every arena reached. The rewards may change over time.

Trivia

 * There was a poll in the Discord Server whether the new highest league should be at 1.5M or 2M merges. 2M won, however it was close.
