When casting Divine Judgement, if I pass priority without floating resources and my opponent floats energy/power using mana abilities without adding other effects to the chain, do I get priority back before the spell resolves?

Ruling: Yes, you get priority back. When your opponent activates mana abilities (add abilities), those go on the chain and immediately resolve without passing priority, but they count as "adding something to the chain" which means you receive priority again when your opponent passes.

Sequence:

• You cast Divine Judgement and pass priority without floating resources
• Opponent receives priority and activates mana abilities (these go on chain and immediately resolve)
• Opponent passes priority
• You receive priority again and can now float your own resources or add effects
• If both players pass priority in succession without adding anything, Divine Judgement resolves

Nuances:

• If you float resources first and pass, your opponent can respond with counterspells like Wind Wall
• The priority cycle can continue multiple times - if you both keep adding things and passing, each player gets another opportunity to respond
• An opponent could strategically float resources to bait you into spending your resources, then counter your spell when they get priority again
