the pokemon card Unique sells for US$16.5 million, smashing world record Pokémon TCG: Scarlet & Violet—151

This can come in the form of Assault Formation effects that reverse how your combat damage is dealt, or maybe Phenax, God of Deception using toughness to mill opponents

You might cast Reforge the Soul and cascade into Whispering Madness, then cast Chain of Vapor which cascades into Wheel of Fate, all while your Waste Not bombards you with zombies / mana / card draw and your opponents watch with disgust at your amazing luck

There are also a bunch of creatures that can get back enchantments, like Auramancer, but I think we have enough better options that I wouldn't recommend running them
