This is a work in progress battle simulator. Right now there's only one option: single elimination tournaments. Eventually there will be more options, you'll be able to rank up as a player, and you'll eventually get rewards too.
Battle results are given in channel, but the full battle details can be found
here.
!newbattle [players] - a mod can start a new battle for the channel
