According to Disney Lorcana co-designer Steve Warner, who told Wargamer a little more about the new cards, Vanishing has allowed the designers to push the boat out when it comes to what a Lorcana card can do, and how much it has to cost
For example, thanks to the straightforwardness of its win-con and its limited requirement for tracking counters or triggered/activated abilities, Limit Break is likely going to be the best choice for new MTG players who are drawn to the game thanks to their love of Final Fantasy
(Though thats definitely part of it.) While comparisons to Magic: The Gathering are easy - there are a number of keywords with specific in-game effects, cards battle using two key values for their attack strength and health, and you can gradually play bigger cards as you build up your stock of in-game resource - Lorcana doesnt just whack a set of Mickey Mouse ears on the veteran TCG
The Shift ability on their card lets them be played for an alternate cost, on top of one of your other characters
