It was indeed Rich Hall playing Doug Henning, as he had in a few SNL sketches during that time, but the sketch you speak of was actually titled "Dueling Magis" and was Doug Henning Vs. Harry Anderson... played by himself. Harry was the host of that episode and a frequent act on SNL.
That said, your memory might be combining this episode with a much funnier and longer skit (20 minutes) from HARRY SHEARER'S HBO Special which parodied David Copperfield's Bermuda Triangle special, with detailed respect for Mr. Copperfield in the process. Very well done.
In it, Harry Shearer plays Copperfield and in the final scenes has a "Duel" with Doug Henning, played by Martin Short, who incedently makes his appearance from "Al Capones Vault".
For those interested, I THINK the sketch is included on Shearers new DVD, called "Now You See It". Hopefully its the full sketch:
