For low-stat cards, keep the ones that have a good spirit ratio, especially the attack-oriented or "leader" cards ones (example: faithful hound, loyal pheasant). They can come in handy for low-spirit teams, which you'll probably want to use against the weaker WGs in tower. For low-stat defense cards, I think you can fuse the majority of them away (like Pale the Interceptor for example) unless you like the art or if the card has a nice attack:spirit ratio as well.
