Many kinds of telekinesis mesh well with melee combat. So does firing off balls/bolts of energy.
More subtle is something I was doing with my 4Ed Warloc/Psion. He had some summonings that let him control small parts of the battlefield (funneling foes to where he could deal with them more easily), and had just started down a path of accumulating abilities that let him attack from unusual angles when the campaign fizzled.
By unusual angles, I mean that he had taken and was slated to take more powers that created duplicates of himself he could place in various places in the battlefield. He could thus have LoS on YOU and Attack without you being able to return the favor.
