2 rulings from Wizards of the Coast
- 25 September 2020A Wizard spell is one with the creature type Wizard. Spells that are Wizard-themed (such as Relic Amulet) aren’t Wizard spells.
- 25 September 2020An ability that triggers when a player casts a spell resolves before the spell that caused it to trigger, but after targets have been chosen for that spell (if it has any targets). The ability resolves even if that spell is countered.
