Reflections of Littjara

  Official Ruling
  If a spell has the kindred card type and the chosen creature type, Reflections of Littjara will copy it.
• WWizards of the Coast2021-02-05
  Official Ruling
  As 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.

  Official Ruling
  The triggered ability and the copy it creates will resolve before the spell that caused the ability to trigger.
• WWizards of the Coast2021-02-05
  Official Ruling
  You 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).

  Official Ruling
  The 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.
