If an opponent plays Smoke Screen and I respond with Discipline (making it 5 vs 5 resources), can I still play Defy to counter the Smoke Screen after Discipline resolves?

Ruling: Yes, you can play Defy on Smoke Screen after Discipline resolves. After Discipline resolves, each player needs to pass priority again before Smoke Screen resolves, giving you the opportunity to play Defy.

Sequence:

• Opponent plays Smoke Screen
• You respond with Discipline (bringing resources to 5 vs 5)
• Discipline resolves
• Priority passes again before Smoke Screen resolves
• You can now play Defy to counter Smoke Screen
