You can do all kinds of fun builds on her and the funny thing is they'll actually work like you'll think building attack speed items will be bad for her as she gains boosts like Psyduck so she won't benefit from them, but nope they actually help her farm and duel, and MS items like Charging Charm synergizes very well with Thief while adding more burst on her passive and the initial damage from Thief.
TL;DR: She has good gameplay and fun builds.
