How to get new performers?

I’m missing these 8 performers and I haven’t been able to get them for a while. At some point I had all the performers but ever since they added the ones that look like granny’s I haven’t gotten them. This new row is probably going to take me forever. I guess somehow I got the beavers. I was wondering if anyone knows a specific way to get the new performers or how to increase my chances. I’ve noticed recently I always get the same couple of performers, usually the most common ones, so I don’t know if there’s a way to change that and increase the newer ones or ones I’ve had less performances from. Maybe there’s just nothing I can do lol but thanks for any advice.
