The former StarCraft 2 professional and Heroes of the Storm addict will head a Team Liquid lineup for BlizzCon.
Four top esports franchises will send mystery teams to compete in the new game.
He's just 16 and already one of the best players in the world.
"We didn't find the fun," Blizzard CEO Michael Morhaime told Polygon.
That makes BlizzCon one of the top 25 esports tournaments ever.
The event already promised to be the biggest tournament Hearthstone had ever seen.
