You can also get Elder Kais through the Baba Shop, story events (three of the ones that are currently available put extra Elder Kais in the Baba Shop), Supreme Kai's Trial missions, World Tournaments, and special celebrations. Usually it's a lot easier to get Elder Kais, than to get a 2nd dupe... so I always open the bottom right path first, even if I have to wait a month or so to get the Elder Kais that I need.
