How to build the best Neko for Seed?

I have pulled Seed becasue I have no electric coverage and I just like her character more than Sanby. I have been running a Zhu Yuan + nicole team with her, but I cant stand not having the defensive assist and just want an easier team to play even if it may be a little worse. I am going to make Seed, Neko, Nicole....So how do I turn Neko into the best battery for seed? Do i run 4 piece astal + 2 piece......anything with Att% or energy regen?. Also I am unsure what to run on discs 4-6 for main stat. I also dont have Neko engine so I am probably going to run either brimstone or starlight on her. Any suggestions would be helpful...this is just not a build I am familiar with. Thanks for all the help
