well if it was really like the midas touch, you wouldn't be able to control it, and it would just be overboard. like you couldn't ever touch your baby without sending it into an LSD trip?
but if you could control it...i'd probably have to say LSD. maybe 2ce if it was proven to not be dangerously unhealthy.
also DMT or DPT might be great ones, but having never tried them before i can't commit. hopefully i could meet one of you superheroes and receive the touch of DxT
