4 rulings from Wizards of the Coast
- 24 January 2020You choose a creature you control for Bronzehide Lion to enchant as it returns to the battlefield. If there's nothing it can legally enchant, it remains in its owner's graveyard.
- 24 January 2020If you control but don't own Bronzehide Lion, you'll return it to the battlefield when it dies, not its owner. It'll enchant a creature you control.
- 24 January 2020If a token is a copy of Bronzehide Lion, it won't return from its owner's graveyard.
- 24 January 2020If a nontoken permanent is a copy of Bronzehide Lion, it returns from its owner's graveyard as an Aura with the two abilities granted by Bronzehide Lion and none of its normal abilities. If it has any enters-the-battlefield replacement effects, those won't apply. The Aura keeps its name, colors, and any supertypes it may have.
