With Twilight Garden you can replace your base game components with a new core set of advancements and vales. This appeals to players who want to use a reset button and experience a set with all new content. Once you play a few games, you can of course add the expansions and base game as well.
Note that this is not a stand-alone release so you still need the base game to play.
Twilight Garden adds new advancement and vale cards to the base Mystic Vale game, giving players more card crafting options and exciting new possibilities for combos. New leader cards grant abilities that can be upgraded to become even stronger! New curse tokens offer players a quicker path to power, but with a price at the end of the game.
