Igglybuff is the cure for Dark Plume. For Slowking. For Aerodactyl (who for some reason was never all that popular). BUT... it's not all that it's cracked up to be. There are ways to beat Igglybuff. One of them (and the simplest is) to KO Igglybuff!!! 30 HP doesn't make it too resilient. The second is... DK Arbok!!! Stare shuts down 1 Igglybuff. If you have enough Slowkings or DK Plumes, it can work. But make sure you Gust out a poke (Before playing your DK Plume) that can't retreat for 3 turns. The third, and best, is to fight! in other words, Attack with your Slowking, DK Plume, or Aerodactyl! Gaze doesn't work on the active!!!
