2 rulings from Wizards of the Coast
- 5 July 2024The target legendary creature copies exactly what was printed on the card in exile and nothing else. It doesn’t copy any information about the object the card was before it was exiled.
- 5 July 2024If either one of the targets of The Animus’s last ability is illegal when the ability begins to resolve, nothing will happen when the ability resolves.
