They are alternate art versions of cards in the main set, they have no borders, a special rainbow foil treatment, and a special rarity symbol

Pricing structure is another reason

If you are capable of healing your cards, through items, actions, or character abilities, and Beast, Tragic Hero has damage on them at the start of your turn, you can let them attack and then heal them, allowing you to still benefit from the increased strength but keeping them healthy enough to stick around

Sometimes they actually could work, but it wouldnt look as new and fresh

Be aware that selling someone else's intellectual property can get you into legal trouble

I also got some sort of content flag on a crab-related card that was apparently too spicy for the app
