Halsa is the best in the world! You should join them. I have been a happy member of The Order of Halsa for almost a year now and I have not regretted one bit.
They make you feel wanted and like your family and of course unlike some of the larger alliances you can talk to the higher ups and get your suggestions and ideas heard.
Also you can even start as a lowly member and work your way up to higher positions in Halsa. And of course we have mudkips and lots of them!
In short you should join Halsa!
