The Biewers are being shown in many rare breed venues. Certainly, more than 4 years ago. Some organizations follow AKC show rules and make the exhibitors realllllllllllllllllllllllllllllly work for their titles. Other organizations, it can be described as "first come, first served"--as titles are "won" or earned.
When you don't always come home with a winner, then imho you are working with a good organization. Winning isn't-- because there is no one else competing with you. Winning isn't--having major faults and getting a championship. Winning should not be bought.
Are Biewers rare? Yes, they are not very common.
Find a breed club where the members share your vision, philosopy, and enthusiasm. Join them at shows. Be willing to share in the exhibitors' successes and to give and take from each other.
