When you do the Twist Sweep from half guard correctly it seems so effortless that people watching think it’s fake. But it works repeatedly in high level jiu-jitsu AND in MMA. From https://www.grapplearts.com/oldguard

Note that that the Twist Sweep is also known as the John Wayne Sweep and/or the Giggler Sweep. No matter what you call it, it’s VERY effective, and even if it fails it still opens up a route to the back for you!
