Apichu - Knight of Cups - All of the knights are on horses, so that seems fitting. Cups deals a lot with emotions/intuition, constantly following his heart to see what is right.
Ben - Eight of Cups - The eight of cups is all about transformation, making new decisions and leaving the old/familiar behind.
Ciara - Ace of Pentacles - The suit of pentacles is all about material gain (not just money, but usually money). The ace of pentacles says that, in order to achieve a goal, one must be organized and plan the journey beforehand.
Chiti - Knight of Swords - Again, he's on a horse, but this knight charges into battle. He may be a bit blind to the difficulties or consequences that his actions may bring, but he's gonna achieve his goal no matter the cost.
Feu - Ace of Candles (aka Wands) - It's the fire suit. The Ace is bold, the wand is on fire, not much else to explain there.
Horace - Page of Wands, Reversed - The page of wands usually represents curiosity and envisioning one's dreams. Horace gets the reverse, comparing his life to that of those around him. He is frustrated by the life he thinks he could've had.
Korrin - Alchemy - One of the few major arcana to be pulled for this group, Alchemy is all about taking dissimilar elements and combining them into something harmonious. This card wants to seek new truths, find a perspective that allows all different aspects of oneself to be acknowledged.
Lorelei - Six of Swords AND Hanged Man (reversed) - Similar to Ben, the Six of Swords represents a transition. This transition is not nearly as painless. It is filled with regret, the result of past decisions, and yet you know the choice is ultimately (probably) correct. The Hanged Man (reversed) says that your suffering cannot continue to be your own escapism. Open your eyes and look at your reality.
Lottie - Eight of Cups (reversed) - Unlike Ben, Lottie is confused AF about what direction to take. She is holding onto the idea of what she once was, and it is preventing her from becoming all that she can be. You cannot constantly compare your situation with your past or your future.
Penny - Four of Cups (reversed) - The reversal of these cups shows a desire to start again. Although life is not perfect, there is beauty to be found in those imperfections. It can also indicate some discomfort or dissatisfaction with oneself.
Yvette - The Magician (reversed) - When upright, the Magician represents a being of pure willpower. When reversed, it shows a being with no direction. They cannot visualize what they desire, there is a lack of connection, there is no purpose in what they do.
