Fervor stacking haunting guise CoC Rosa. I'm not sure I would recommend this it was a lot of FE for what it does, but if you're looking for an offmeta brain off 8-4 Farmer it's a good build.
Eternal isn't necessary, but there's a noticeably amount of ramp at the start of each map anyways, so I usually just run it for fun.
