In this battle this is a clear warior vs monster battle and I will take the warrior anyday. Clay face is a beast and his abilities would make him a huge threat against most enemies but Dead pool is a trained killer who is not going to scare easily. He is a trained assassin who has the ability to keep Dead pool off balance while he figures out the best way to handle him. Also if Clayface was able to get an advantage on Deadpool, Dead pool has his healing factor to keep him in the fight. Lastly let's not forget Deadpools greatest weapon, he is completely insane and unpredictable. Clayface would have no way to adjust and adapt to Deadpools level of crazy.
