3 rulings from Wizards of the Coast
- 5 February 2021If a spell targets Goldspan Dragon more than once, the triggered ability will trigger only once.
- 5 February 2021An ability that triggers when a creature becomes the target of a spell resolves before the spell that caused it to trigger. Such an ability resolves even if that spell is countered.
- 5 February 2021Players can cast spells and activate abilities after the triggered ability resolves but before the spell that caused it to trigger does.
