Recommendations on a group hardcore builds?

Hello, I am a longtime poe, and hardcore poe player. My wife agreed this league to play hardcore with me after we finished what we wanted to accomplish in standard. We are satisfied and moving into hardcore

What builds would you guys recommend? Keep in mind its party play, so stuff like combo skills matters (for example, a lightning arrow build has both players benefit from lightning rod. A build with a bell lets a wide range of builds benefit from hitting a bell, etc)

Btw if anyone has never tried hardcore but has been wanting to, I think this is the league to do it. Martial artist's tattoo ascendancy massively helps with resistances and allows for a much wider set of gearing to be hardcore viable.

Thanks for any recommendations!
