Is a recall (such as from Zhonya's effect bringing a unit back to base) considered a move?

Ruling: Recalls are not moves. This is explicitly stated on recall cards.

Nuances:

• A "corrective recall" is a special case where something would be in an illegal location, so it gets recalled to base instead. This rarely happens and requires an effect that forces a unit to be somewhere illegal.
• Standard recalls and corrective recalls are both not considered moves.
