2 rulings from Wizards of the Coast
- 19 March 2021Prized Amalgam's ability triggers only if it's in your graveyard immediately after an appropriate creature enters the battlefield. A Prized Amalgam that's already on the battlefield won't be returned at the beginning of the next end step if it's put into your graveyard later.
- 19 March 2021A card cast using its madness ability is cast from exile, not from your graveyard.
