Does Flurry of Blades require paying the recycle cost for Deflect when there are multiple units with Deflect at battlefields?

Ruling: Flurry of Blades does not require paying recycle costs for Deflect because it does not target units.

Nuances:

• Flurry of Blades programmatically selects units rather than having the controller choose targets
• The phrase "deal 1 to" does not mean targeting - the spell blankets all units at battlefields without the controller making choices
• Unlike targeted spells which cannot be played without valid targets, Flurry of Blades can be played even with no units at battlefields
