You have been working as a carnie for years. Naturally you'd be good at faking a fight. What would happen if you did that for real? Pain....lots of pain. 

You can run at an enemy and deliver a dropkick dealing 2d20 damage and sending them 15ft back, prone. This deals half damage to your since you're jumping into the air and landing on your back, prone.

You can pick up an enemy and slam them forcefully into the ground in a chokeslam dealing 1d20 damage and knocking them prone.

You can put their head under your armpit and drop straight backwards delivering a DDT and causing 2d20 damage, knocking the enemy prone but you take half damage since you're dropping straight backwards. 

You can run at an enemy and deliver a "spear" which is a shoulder tackle that knocks both of you prone dealing 1d20 damage. 

You can give your opponent a tombstone piledriver dealing 2d20 damage followed by a "1,2,3!" pinfall dealing an extra 1d20 Psychic damage to every enemy who sees another person's head driven into the ground.

You can climb to a high point no higher than 5ft off the ground and land a "top rope" style dividing maneuver of your choosing. This is done using an athletics or acrobatics check to determine the height of your jump. Your attack will do 2d20 bludgeoning as well as 1d20 falling damage to the opponent per every 10 feet of jumping height you achieve with your check. 

Everything can be countered with the usual saves and checks.
