How do you approach playing a Spirit “blind”?

How do you guys play a Spirit for the first time?

My method involves doing a bit of research on builds and strategies for said Spirits before playing them.

That takes a bit of time, but sometimes I just wanna jump in on a new Spirit I’ve never read about before. The problem is when I do, I get immediate analysis paralysis: I don’t know which Growth to pick, which Spirit track to go through, which cards to draft, etc. Any advice?
