Screw it, its been a while. Im in and ill enter with Gengar (f)

So....something creepy?

Ok Gengar lets set the atmosphere. Use a Haze to roll in a nice thick fog over the arena. Make sure it gets into the crowd so it gives them chills.

Follow that with a 'gentle' Ominous wind, again pushing outwards so the clearing haze rolls out slowly through the crowd to really get the creepy tone.

Finally use that Ghostly body of yours to hide in the fog for as long as possible, moving invisibly from where you were in center stage before popping up with Scary Face, right in front of the crowd!

That should get some pulse's racing.
