Can you play cards (react) between each link of a chain as it resolves, including playing a card drawn from a chain reaction?

Ruling: Yes, you can play cards between each link as a chain resolves. Each time an item on the chain resolves, the controller of the next item gets priority, and both players have a chance to react in between each chain item.

Sequence:

• A chain item resolves
• The controller of the next chain item gets priority
• Both players can react before the next item resolves
• This continues until the final chain item

Nuances:

• You cannot react to the final link in a chain resolving - it does not pass priority
• In a showdown, you will have another chance to act before might is increased again
