Does the chain in Riftbound resolve all at once like Yu-Gi-Oh (chainlock), or can players respond between individual resolutions like Magic: The Gathering?

Ruling: The chain functions like Magic: The Gathering - players can respond between individual resolutions. There is no chainlock; only one item resolves at a time, and players receive priority to play cards or activate abilities before the next item resolves.

Sequence:

• When an item on the chain resolves (Step 4: Resolve), only the topmost item resolves
• If the chain is not empty and there are no pending items, the controller of the newest item on the chain gains priority and becomes the active player
• Return to Step 2: Execute, where the active player may play a card, activate an ability, or pass priority
• If they pass, the other player gains priority and may play cards/abilities or pass
• Once both players pass consecutively, the next item on the chain resolves
• This process repeats until the chain is empty

Nuances:

• Priority after resolution goes to the controller of the next item on the chain, not necessarily the player who last played something
• You can draw a card from a resolving effect (like Consult the Past or Discipline's cantrip) and cast it before the next item on the chain resolves
• Focus and priority are different concepts: Focus allows starting a chain during a showdown and passes automatically when chains empty; Priority allows playing items on an existing chain
