Sorare Fantasy Baseball is taking the MLB world by storm, so let's take a look at how tournaments and rewards work. Thankfully, the system is very accessible and easy to understand.
Sorare runs tournaments that can be found in the lobby of their site. This is where you can pit your teams against other users. Right now, all tournaments are "Common All-Star" tournaments that anybody can join. If you win enough of those tournaments to get rare player cards, you'll be ready for the higher scarcity tournaments starting in August.
Sorare MLB tweeted about the upcoming Rare All-Star tournaments that will be opening up soon.
