Riftbound’s updated tournament rules take effect on October 16, alongside the start of Radiance Pre-Rift events. Riot Games describes the October 9 changes as a broad clarification pass informed by feedback from the judge community. The update explains when a player can change a gameplay decision. At higher

organised-play levels, players cannot undo a move after an opponent is required to point out information that exposes their mistake. Casual events can encourage more flexibility for learning, although an opponent is not required to allow a takeback. Other changes clarify deterministic loops, bluffing about private

information, token readability and when outside notes must be put away before mulligans. The document also adds Radiance to Standard and updates deck-registration requirements for unusual construction rules such as Neeko’s. Organisers and players can consult the complete tournament document before this week’s events.
