Careful calling a bloke who killed his whole family just for a sword "bad".

Olivia, palla (been powercreeped tho), hinata, lonqu I guess would patch his poor attack.

Selena and Hana are solid choices too, especially if you add Wrath as well.

Not saying my Karel is very good but I try to salvage all of my 5 stars, so my +HP - Spd Karel become a.... reprisal bomber?? lol

Any sword unit that doesn't have a preferential and kind of lowish atk.
Palla, Caeda, Selena, Hana, Olivia, Draug, Fir, Lon'qu

Give back Fir the crit sword that made her shine in Binding Blade.
