2 rulings from Wizards of the Coast
- 20 March 2026An opus ability resolves before the spell that caused it to trigger. It resolves even if that spell is countered or otherwise leaves the stack.
- 20 March 2026You pay all costs and follow all timing rules for cards played this way. For example, if the exiled card is a land card, you may play it only during your main phase while the stack is empty and only if you have an available land play remaining.
