B! Sanaki viable? -atk +def

She still has 50 atk. Not great, but still useable.

33 Atk is still pretty high considering she can get 5 more from the bond skill, 3 more from her tome, and up to 6 more from the tome effect. Otherwise, bladetome set will also more than make up for the atk bane but her budget set is already great. For many tome users, her neutral atk is like a boon for someone else's but they don't nearly get as much opportunity for stacking atk unless they do bladetome.
