How much is the most expensive Magic?

I'm curious to know, could you elaborate on what you mean by "the most expensive Magic?" Are you referring to a specific collectible card game, such as Magic: The Gathering, and inquiring about the highest valued card or deck within that game? Or perhaps you're asking about a different type of "magic" altogether, like a unique or rare item in the world of cryptocurrency or digital assets? Regardless, I'd be happy to help answer your question, but I'll need a bit more clarity to provide an accurate response.
