If my opponent uses Charm on my unit at a battlefield and I respond with Flash to move that unit to base, does Charm still resolve?

Ruling: Yes, Charm still resolves even if the targeted unit has moved to a different location (including base) before Charm resolves.

Nuances:

• Charm does not specify where the unit must be located when it resolves
• Since the unit is now at base, Charm cannot "move" the unit to where it currently is (base)
• When Charm resolves, you can still move the unit back to a battlefield or to another battlefield, since move effects target the unit (not a location) and the destination is chosen at resolution
