Wizards of the Coast has made a significant move towards producing more collaborative sets with existing franchises, particularly following very notable sets like The Lord of the Rings and Fallout over the last few years
Revival Trance Featuring Terra from Final Fantasy VI as Terra, Herald of Hope, Revival Trance is a deck built around getting cheaply costed creatures into your graveyard, then reanimating them using her ability
She has a cost of 7 Ink to get into play, but if you use Shift to play her on top of an Ursula already in action, you can reduce this to 5 Ink
They didnt want tough characters like Mufasa to be stuck in the Silver ink color and allow players building decks to have access to multiple versions of the same character
Perhaps they could take a more obvious approach with their rarities like Magic: the Gathering, with its Prosperity cards in Outlaws of Thunder Junction, or even add another layer of Disney magic to cards like with Star Wars Unlimited's Hyperspace rares
