Can you play the Bird tokens from Flurry of Feathers directly onto a battlefield you are attacking?

Ruling: No. You cannot play the Bird tokens from Flurry of Feathers to a battlefield you are attacking because you do not control that battlefield. The tokens follow all normal rules for playing units, which require you to play them to your base or to a battlefield you control.

Nuances:

• When attacking a battlefield, an opposing player controls that location, so you cannot play units there.
• If you don't control any battlefields, you must play the tokens to your base.
