#2 The debut of LAX
Heading into All Out, there was speculation that LAX was signing with AEW over WWE, and following the Escalara De La Meurte, the news was confirmed. Two men entered the ring wearing presidential masks, and attacked both of the teams after a hellacious contest, before removing the masks to a fantastic ovation from the sold-out Sears Center crowd.
The All Elite Wrestling tag team division was already stacked (8 fantastic tag teams competed at All Out), so adding Impact Wrestling's Tag Team of the Year from 2018 makes it perhaps the best tag team division in history. The name LAX wasn't mentioned specifically, so while we don't know what they will be called when AEW start TV on October 2, but given the AEW World Tag Team Championship Tournament that will be getting underway, it's safe to say that these two made the right choice by going with AEW.
