The fastest I have are Entangling Bones and Green Demon. When they are hitting on all cylinders, we’re talking 30-60 second fights against 9,600+ teams.
The speed of these two teams is not always reflected in the videos I make demonstrating them, because when I capture the video footage I am dividing my attention between playing, keeping my words straight, respecting production values, etc and I screw up a lot 
When you feel comfortable with them and can play them without thinking, it’s just downright silly how fast you can wipe out top teams.
