Cloud9 and 100 Thieves are looking for League of Legends players through free classified ads in newspapers. This was reported by the reddit user, who published a clipping from the newspaper on the subreddit game.
In the comments to the post suggested that the American clubs are not going to recruit players in this way. Ads are needed only as a formality. They will serve as proof that there are no specialists with the necessary qualifications in the USA. So Cloud9 and 100 Thieves will make it easier to get green cards or work visas for their foreign players.
