2 rulings from Wizards of the Coast
- 19 September 2025Mayhem represents an alternative cost that can be paid to cast a spell from your graveyard if you discarded the card with mayhem that turn. You must pay any additional costs the spell has.
- 19 September 2025You must follow all normal timing rules when casting a spell with mayhem. For example, you can't cast a creature card with mayhem you couldn't normally cast during an opponent's turn, even if you discard that card during an opponent's turn.
