This pack provides an interesting selection of new leaders and lore to supplement the ones already present in the base game of arcs. These are generally more complex and difficult to conceptualize, so they're a good way to inject some longevity into the game but may be a bit too much for brand new players to grasp.
Instructions are clear in this step by step Lorcana playground, which is very good for beginners. It teaches you slowly how to play each type of cards and increases complexity slowly. This is a lot better learning experience than Ursula's Deep Trouble. The game also came in excellent conditions. Very recommended.
