I *think* I have found a decent trickster setup
The build: Monitor and abuse, enduring (fun) or ruin (good), corrupt, any other perk (pref pop or sloppy).
The point of this build is completely reliant on monitor and abuse, his near enough silent terror radius and his very short height.
See where I'm going with this?
Literally just play him like a stealth killer but you want to get hits as soon as possible, if you get a hit with m1 or laceration, drop chase and go to someone else. Then keep up the momentum of injures or go back to anyone injured to secure a down. Nurses would help and if you have weak gamesense I would most certainly recommend taking it or whispers as your last perk
PRIORITISE M1S OVER LACERATION, only use blades at loops where you know you cannot m1 them.
Basically hit and run.
His power is so weak that playing him the "intended" way will result in more losses than playing perkless clown against 4 mans. How this weak of a killer managed to actually make it live is beyond me.
If anyone else has found any strategies please feel free to comment it I really want this dude to be good.
EDIT: If you are trying this I would recommend purchasing one of his darker cosmetics so you don't stand out like a sore thumb when traversing the map.
