This is another way of playing Sejuani. Most of the players think that Sejuani has to be a tank or an ap tank, but with her slowing abilities she`s really good for chasing with an attack damage build. In this Guide you will be a support tank till you got your Atma`s. I recomment this Guide for 3v3 because you can gank in early game really fast. I think the items I`ve chosen are self-explanatory. I hope you will try this out.
Have Fun
