How do you get the Championship Bunbun Icon?
It was released for Teamfight Tactics. Riot's description in the client reads: “An icon that celebrates a 2023 Teamfight Tactics event.”
Is the Championship Bunbun Icon still available?
No. Riot tied the Championship Bunbun Icon to 2023 (Teamfight Tactics), and it does not normally bring back past event rewards or bundles.
