Boosters don't count? Interesting.

Regarding results, death by magic duel isn't treated differently from other deaths AFAIK. If you wanted it *gone* in one shot, you'd need to use something like Banish to Inferno or Claws of Cocyctus (sp?), although with a Chayot's stats it might not be too long before it breaks free.
