It’s definitely not October just yet (don’t worry), but today does mark the start of Oktoberbrawl, Blizzard’s Hearthstone event pitting the entire community against each other while two teams of three players engage in a month-long Battle for supremacy. Your prize for participating? Two unique card backs.

Battles kick off today, with Team Void’s Dog, Thijs, and J4CKIECHAN taking on Team Light’s Kripparrian, Reynad, and Alliestraza. Each player starts with a fresh account for the battle, and support from the community will determine which team gets to pull from a pool of additional boosters.
