How do you get the SSG Jarvan IV Icon?
It was a mission or event reward. Riot's description in the client reads: “Honoring Ambition's winning Jarvan in the 2017 World Championships, SSG Jarvan shows humility in victory and defeat.”
Is the SSG Jarvan IV Icon still available?
No. Riot tied the SSG Jarvan IV Icon to 2018 (mission reward), and it does not normally bring back past event rewards or bundles.
