Welcome to Riftbound, the League of Legends trading card game! The Riftbound Core Rules (CR) are rules that govern Riftbound play at all levels. They make up one component of the Official Rules Documents (ORD).
The Core Rules provide the precise logical underpinnings of Riftbound gameplay. This includes deckbuilding rules, timing and resolution of cards and abilities, layering of effects, and all the other fine-grained rules that define the flow of a Riftbound game in all possible configurations. These rules are always in effect at every level of play, but you should be able to play casual games of Riftbound without ever needing to consult them.
The Core Rules will be updated frequently. At minimum, they will be updated with every set release to ensure that all the new cards and their abilities function as intended. They may be updated more frequently especially early on, to make them ever more complete and correct.
