Does banishing a card (such as using Portal Rescue on Kayn) count as moving it?

Ruling: No, banishing a card does not count as moving it. A banished card leaves play entirely, and moves can only happen between Board Zones, while the Banish space is a Non-Board Zone.

Nuances:

• When a card is banished and returns, it becomes essentially a new card (loses previous state/memory)
