Yu-Gi-Oh related Question

Yu-Gi-Oh is an anime series and a card game. It has nothing to do with real magic or real psychic abilities. While such games sometimes contain a kernal of truth about magic, you cannot take them for fact. As you said in your profile, you sometimes have trouble telling fiction from reality. In this case, what you are asking about is fiction.

Lark... nightmare 87 isn't asking about something that is flat-out fictional.
Specifically, the question is "How could one attain the ability to read minds or be able to see physical things that they otherwise couldn't?".

So, nightmare87, the topic you used was a little misleading, but it's fair as you didn't realize that it could be misunderstood easily.
You're looking for clairvoyance or mind-reading.
I can't actually answer your question, since I don't know how you would gain these abilities if you weren't born with them. Sorry about that.

Actually he was asking about becoming a "psychic duelist" as in the category in the Yu-Gi-Oh game. Which is a fictional thing. He states that more clearly in his Profile.

Lark
I know plenty about Yu-Gi-Oh, but he isn't talking about the monster type "Psychic".
If you could just ask for clarification, you would understand that you're being a little unreasonable here.

If you do mean materializing monsters for real, I apologize for misunderstanding and that actually isn't possible as far as I know.

Even if it he was asking just about reading minds, that is still impossible.

Plenty of these Japanese anime shows are full of magical delusions, and perhaps such supernatural theme is what makes them a hit.

so I can't become a Yu-Gi-Oh duelist that can use some of the abilities that the Millennium items or psychic duelists from Yu-Gi-Oh 5Ds have?

Cause I just want to have/use the same abilities as the Millennium Eye. And those abilities are: mind reading, being able to see your opponent's cards and know their strategies.

No you cant read other peoples minds or see through things to see whats on the other side or anything similar to that.

In regards to strategy that is something you can learn by watching people and seeing what they do most frequently and basing your actions according to their most likely move.
