How do you get the iG Kai'Sa Icon?
It was a mission or event reward. Riot's description in the client reads: “Honoring JackeyLove's winning Kai'Sa in the 2018 World Championship.”
Is the iG Kai'Sa Icon still available?
No. Riot tied the iG Kai'Sa Icon to 2019 (mission reward), and it does not normally bring back past event rewards or bundles.
