Bridals builds?

Today I was really lucky with this banner. I've got an Eldigan (which I will use him as Fury fodder bc I already have a good one) in the free summon, and then Sanaki (+res -atk) and Tharja (+res -spe), both in the same summoning session.
I want to use them both, but I don't know which skills inherit them, so any build ideas for the bridals?

And as a bonus, the proof of my lucky. Funny thing that I summoned normal Tharja after I get Sanaki. xD
