How important to get expired domain for dropshipping

Hello,

I just wanted to ask how important is to get expired domain for dropshipping?

I am going to do some seo on my new dropshipping website so before creating it, I think it would be better to create my sore on expired domain to get better seo results.

For example, I want to create my store in unicorns niche, so maybe someone could suggest me what is the best way to find expired domains for niches?
