It is interesting to see that Shimmering Skies starter decks do not have any cards from previous sets, but then Azurite Sea has a mix of only sets 5 and 6
Remember youll always want to see a nice curve with cards you can play on turns 1, 2, and 3 without more than two uninkables to start
Madam Mim, Foxs Chasing the Rabbit ability allowed me to return a character from the board to my hand, which meant I could bring back damaged ones or trigger powerful effects from cards entering the battlefield over and over - when Merlin, Goat, which gains a lore each time it enters and leaves the battlefield, turns up you can see where the game really starts
Amethyst can always be improved with the Bounce package of Merlin and Madam Mim characters
That said, which Lorcana starter deck is best for you may depend on how you like to play and how familiar you are with other trading card games, such as Magic: The Gathering
