Because Stitch - Rockstar from The First Chapter or Into the Inklands share the same name and version as Stitch - Rockstar in Fabled, you may use any of them in a Core Constructed deck, and it’s considered to be from the latest print run, regardless of which set it’s from. We understand this may take some getting used to, but encourage you to use tools, like the deckbuilder in the Disney Lorcana TCG Companion App, to help you build your decks with the latest cards.
So that means while four sets are leaving the card pool in this first rotation, we’re selecting a significant number to stick around, the majority of the set in fact! Whether it’s because we’re happy with the impact they’ve had on the game, or they might not have gotten their time to shine.
