Does anyone know which deck this is?

I was thinking the same thing. I was hmmmm.... which Photoshop filter has that been subjected to? I think it's colored pencil or the smudge stick filter

Good question. Maybe a combination of things?

I don't have Photoshop, but I was able to get a similar effect with Gimp's "cartoonize" filter + adjusting contrast and saturation.
