After an opponent responds to triggers on the chain and their response resolves, does the player who controls the remaining triggers regain priority before those triggers resolve?

Ruling: Yes, after each individual chain item resolves, priority is given to the player that controls the next item on the chain, and priority must pass between both players before the next item resolves.

Sequence:

• Triggers go on the chain
• Opponent responds (e.g., with Stupify)
• Response resolves
• Priority returns to the player who controls the next item on the chain
• Priority must pass between both players
• Next chain item resolves
