While the three decks are carefully balanced against each other, they each focus on differing play styles - corresponding to their different combinations of two ink types from the six card colours in Lorcana - so some may be easier to handle or more satisfying if you prefer to play a certain way
Mickey is also cheaper, inkable, and the accompanying Brooms allow you to return cards from your discard pile back to your deck providing insurance against decks that aim to win through deck out (more on this later)
We also are getting Wizard Pooh sleeves which is cool
However, unless you live in a country where the card has already been given away along with tickets for Moana 2, you won't have been given the chance to add it to your collection
However, Id be more interested in combining this Floodborn Robin Hood with the Robin Hood from Rise of the Floodborn
Dont add all of your high-cost cards to the Inkwell, or you may not have strong cards to play later in the game
