When a unit is moved by an ability (like Charm or Yasuo's legend ability) rather than by the standard move action, does it exhaust itself from moving?

Ruling: Units only exhaust to move when using the standard move limited action. When moved by abilities or effects outside of the standard move action, units do not exhaust themselves from the movement.

Nuances:

• A unit moved by an ability while readied can then be exhausted to use the standard move action to move again
• Yasuo's ability can be used on an exhausted card
