If a unit with Deflect is targeted by a damage spell, and Unyielding Spirit is played in response to prevent the damage, does Deflect still trigger?

Ruling: Yes, Deflect still triggers even if Unyielding Spirit prevents the damage.

Sequence:

• Opponent targets the unit with Deflect using a damage spell
• Deflect costs are paid when the unit is targeted
• Unyielding Spirit is played in response
• The spell deals 0 damage due to Unyielding Spirit, but Deflect has already triggered
