Um, because you need some Lele for Sylveon to work properly. You can't really play Sylveon without some Lele in your deck
I play Sylveon cuz it's annoying. That's all I am. Normally I use volcanion. How did you even know I had two lele?
Yeah, Lele isn't needed, but for a distruption deck it really helps if you have the supporter cards you want as well as the items you want
