Bucket list succs?

I’m getting to the point in my collection where I have versions of most of the common types of succulents and only seem to find 1 plant I NEED at a time walking around my local garden store. I also love “window” shopping online when I’m stressed (and this has been a stressful week).

For those of you who have been collecting even longer, what are your bucket list plants? The ones you’ve been searching for for months or years? Let’s dream together.
