Can Moonlit Fae ready a unit that moved with her using her ready trigger effect?

Ruling: Yes, Moonlit Fae can ready a unit that moved with her. Exhausting units is a cost paid before the move happens, so when MF's ability triggers after moving, the unit that moved with her is already exhausted and can be targeted by her ready effect.

Sequence:

• MF and the unit are exhausted to pay the cost for standard move
• MF and unit move together
• MF's ability triggers
• MF uses the ability on the currently exhausted unit
