Which LoL champion says ‘Precision and grace’?

There are many precise and graceful champions in League of Legends, but only one of them says this quote in the April 3 LoLdle.

I completely blanked when I first saw this quote, so I had to give it a few goes before finally landing on the answer. In my experience, these short quotes tend to be the trickiest. It doesn’t really give much away on the face of it. My first instinct was Diana for some reason, but it didn’t add up.
