Considering the relatively low ink cost of all three Ducktails nephew cards, getting this ability rolling early on in a Lorcana game is entirely plausible, as well as being excellent gameplay-wise thanks to the advantage that additional card draw can get you
It has some generic uses, buffing a friendly creature with counters based on its power, but beyond that, it doesnt really synergize with other cards, especially those from the Final Fantasy set, but thats about to change
On the one hand, a set rotation does help newer players to the game
The new Wreck-It Ralph characters Vanellope and Snowanna, for instance, have the rush ability to challenge opposing characters as soon as they are played, but dont have a huge benefit like the current Amethyst/Ruby decks do when potentially trading characters in this way, such as drawing when banished
