How do you get the Firecracker Poppy Border Icon?
It came in a bundle. Riot's description in the client reads: “An icon that entitles the border for this champion.”
Is the Firecracker Poppy Border Icon still available?
Maybe, while it lasts. Riot tied the Firecracker Poppy Border Icon to 2026 (bundle). It does not normally bring back event rewards or bundles once they end.
