Best Trick and Best Tricker.
 

I say the best trick was in Nightmare 3 (Dream Warriors) when Freddy to the form and figure of Nancy's dad and then when they ( Nancy and her "Dad" ) were hugging her "dad" Freddy toke his true form and stabed Nancy. I'll have to say Freddy and Chucky are the two best tricksters.

"The greatest trick the devil ever pulled was convincing the world he didn't exist."

The Usual Suspects

i thought a good trick was when freddy got joey to go inside of his water bed when he was that naked model.
