Overall, this is the most interesting of the two decks recently released and it can be easily improved by boosting the Sapphire portion of the deck adding some items from Chapter 2 and Chapter 1 and other cards that reduce the cost of playing/benefit from having items in play (Belle Inventive Engineer or Ariel Whoseit collector for example)
The Disney Lorcana booster packs cost $5.99/4.99 and contain 12 random cards for you to build and customise your deck with.
Pluto, Friendly Pooch is a great tool that helps this deck put the pressure on, and I expect it will have a place in the Into the Inklands meta as well
In terms of a Starter Deck for newcomers, both work well and are easy to pick up and learn
As per usual, the cards will be able to be mixed with others from The First Chapter and Rise of the Floodborn , as long as no more than two inks are represented per deck
We'd love to help you find the right starter for you so you can continue to enjoy playing Disney Lorcana.
