Later in the new season, you'll be able to earn Mastery Chests and Keys as you team up and compete with your friends. Upon acquiring (and combining) the two, you'll be able to unlock the chest, earning loot items ranging from 7-day rentals to permanent skins and champions.

I'm all about the champions part. I may finally get them all.
