Each card has a rule that needs to work exactly as written, without being interpreted wrong
There are, however, two things you should know about the back faces of these cards
You dont even necessarily need to have self-mill cards like Town Greeter, Shinra Reinforcements or Vanille, Cheerful lCie (though those should absolutely be prioritized)
The card you leave in your graveyard could be as simple as a huge haymaker like Jin-Gitaxias, Core Augur
But the rare card also has a single ability called 10,000 Needles, which is excessive in a way that only Final Fantasy abilities can be excessive: Whenever this creature attacks, it gets +9999/+0 until end of turn. Do you need to deal 10,000 damage to another creature in a game of Magic ever
Featured within the new Lorcana cards will be the first appearance of the Madrigal family - from the animated film Encanto - within the trading card game, alongside iconic favourites like Mickey Mouse and Mulan
