Waver+Hans/Mash is great for any damage dealer, including Jack since all the buffs are universal, it doesn't matter their color. Skadi isn't here so yeah.
You can also do a quick team but those are kinda meh...or use her as an star generator
Jack is great at making star, pair her with someone who like to crit like lancelot or rama, both of them can crit hard lancelot being easier to set up since his crit buff more sustainable compare to rama
I like Waver/Jack/Altera, Alteras high attack stat makes great user of Jacks stars, especially after her skill upgrade.
Really Jack + Waver goes great with any buster/crit servant. Herc, Emiya, Kintoki rider and Saber Lancelot will all use the stars generated by Jack well and Herc.
