Does 'passing priority without adding any items to the chain' mean without adding items during that specific priority window, or does it mean passing consecutively without any items added since the last pass?

Ruling: When you pass priority, it always counts as passing without adding anything to the chain, regardless of whether you added items to the chain before deciding to pass. If both players pass consecutively without either adding anything during their respective passes, the chain resolves.

Sequence:

• Player A adds one or more items to the chain, then passes priority
• This counts as passing without adding items
• Player B receives priority
• If Player B also passes without adding items, the chain resolves
• If Player B adds an item to the chain, the cycle resets and both players must pass consecutively again

Nuances:

• The game is designed to prevent "testing the waters" by waiting for opponent reactions before committing to plays
• Players hold priority by default, so passing is an explicit decision
• The 1.0 rules were clearer on this point, stating "If all Relevant Players have passed once in sequence, nothing else can be added to the Chain and the Chain ends"
