When Fight or Flight is played on a ready unit, does that unit exhaust?

Ruling: No, the unit does not exhaust. Only standard moves have an implicit exhaust cost. When a spell tells you to move, you only do what the spell says.

Nuances:

• Standard moves require units to exhaust themselves as a cost to move
• When a card effect says "move," it provides free movement without requiring the unit to pay the exhaust cost
