Sapphire has two key cards that act as payoffs for your extra ink: Belle, Strange but Special and Hades, Infernal Schemer
You may want to consider putting more Kuzco, Temperamental Emporers and Genie, On the Jobs if you want to play a more high-risk, high-reward deck
There are three starter decks available for purchase as part of the first set of cards, called The First Chapter, but for players looking to create a deck that caters to their own play style, or favorite characters or are just looking to mix it up and try something new, crafting a new deck is worth the time
For decks that favor aggro play, that's borderline criminal, and when paired off with some constant Amber staples like Set 1's Lilo Making A Wish, it makes for a formidable early-game hand
