You seem to not be experienced in yugioh, you may think you are but person who knows prices of cards would know if a card like that is playable, which it is odviously. Next time simply ask if slifer is playable so you dont look twice as silly :)
Appearently not, and I hope so cause you are claiming my cards are worth less then they are because you cant grasp the fact that yugioh cards are expensive, especially the good ones
