5 rulings from Wizards of the Coast
- 5 February 2021If a spell has the kindred card type and the chosen creature type, Reflections of Littjara will copy it.
- 5 February 2021As a copy of a permanent spell resolves, it's put onto the battlefield as a token rather than putting a copy of the spell onto the battlefield. The rules that apply to a permanent spell becoming a permanent apply to a copy of a spell becoming a token.
- 5 February 2021The triggered ability and the copy it creates will resolve before the spell that caused the ability to trigger.
- 5 February 2021You must choose an existing creature type, such as Zombie or Angel. You can't choose card types (e.g., artifact) or supertypes (e.g., snow).
- 5 February 2021The token that a resolving copy of a permanent spell becomes isn't "created." Abilities that refer to a copy being created won't interact with the copy resolving.
