Can Someone Help Me Clarify This...

About Championship Riven : Hippalus mentioned here

Most limited edition skins came back into the store 4 years after release and therefore one possible scenario is to bring her back during the 2016 playoffs as part of a 5 skin Championship bundle with Thresh, Shyvana, etc.

"... bring her back during the 2016 playoffs AS PART OF a 5 skin Championship bundle..." Does that mean you can buy Championship Riven ONLY together with the bundle or it could be purchased individually?
