Where do I find that old article on animation?

Hi everyone. A while back, Riot released an article on how they do their animation. It featured the face movements of Tristana or Poppy (I forgot) and how they animated Yasuo's ultimate by stretching out his sword for a stylized effect. Does anyone know where I can find it?

As someone who's always been interested in working in the game industry, that article really inspired me. And since I am now starting game asset and animation courses in Maya, 3dsMax, Unreal, etc.; I've been wanting to look back at it but I can't find it! Please help. :)
