Can Hallowed Tomb return a copy of your chosen champion from trash to the Champion Zone if another copy of that champion is currently in your base or at a battlefield?

Ruling: Yes, you can return a copy of your chosen champion from trash to the Champion Zone even if another copy is in your base or at a battlefield. Your chosen champion is defined by the card name that started in the Champion Zone, not the specific physical card.

Nuances:

• The chosen champion identity is tied to the card name, not to a specific physical copy of the card
