If Warwick moves to a conquered Battlefield, opponent plays a damaging spell, and you respond with Unyielding Spirit then Flurry of Blades, how does the chain resolve? Does Flurry deal damage before Unyielding Spirit prevents damage? Does Unyielding Spirit save Warwick from the damage spell? Does Warwick's ability still wipe the battlefield even with Unyielding Spirit active?

Ruling: The chain resolves in reverse order: Flurry of Blades deals damage first, then Unyielding Spirit prevents the damage spell from harming Warwick, then Warwick's attack trigger resolves and wipes the battlefield (since Warwick's ability doesn't deal damage, Unyielding Spirit doesn't prevent it).

Sequence:

• Flurry of Blades resolves (deals damage)
• Priority opens, double pass needed
• Unyielding Spirit resolves (prevents incoming damage)
• Priority opens, double pass needed
• Damage spell resolves (no damage dealt due to Unyielding Spirit)
• Priority opens, double pass needed
• Warwick's attack trigger resolves (wipes battlefield)

Nuances:

• To play both Unyielding Spirit and Flurry of Blades in response to the damage spell, you must play Unyielding Spirit, keep priority, play Flurry of Blades, then pass priority. You cannot play Unyielding Spirit, pass priority to see if opponent responds, then play Flurry of Blades.
• Playing a card does not automatically pass priority in Riftbound - passing priority is a separate action you must take after playing cards.
• After each item in the chain resolves, priority opens again and both players must pass in sequence before the next item resolves.
• Warwick's ability does not deal damage, so Unyielding Spirit does not prevent it from wiping the battlefield.
