How do you get the SSG Ezreal Icon?
It was a mission or event reward. Riot's description in the client reads: “Honoring Haru's winning Ezreal in the 2017 World Championship, adventure into the Fog of War as SSG Ezreal with a quick escape on hand.”
Is the SSG Ezreal Icon still available?
No. Riot tied the SSG Ezreal Icon to 2018 (mission reward), and it does not normally bring back past event rewards or bundles.
