When Unyielding Spirit is played in reaction to Flurry of Blades, and the opponent then plays Cannon Barrage in reaction, does Unyielding Spirit prevent the Cannon Barrage damage?

Ruling: Cannon Barrage damage is dealt and not prevented by Unyielding Spirit. Flurry of Blades damage is prevented.

Sequence:

• Flurry of Blades is played
• Unyielding Spirit is played in reaction
• Cannon Barrage is played in reaction
• Stack resolves top-down: Cannon Barrage resolves first (damage is dealt), then Unyielding Spirit resolves (preventing subsequent damage), then Flurry of Blades resolves (damage is prevented)

Nuances:

• The stack resolves from top to bottom, so effects that were added to the stack later resolve before effects added earlier
• Unyielding Spirit only prevents damage from sources that resolve after it does
