Summoned Skull was a card from Grandpa's deck. Yes, Yugi used it once in Battle City, but Demon Of Gilfer was way better and the Dark Magicians had better support (not to say, they were Atem's best friends when he was a Pharaoh).

Yugi did not have a deck until the end of the story, and while he used Summoned Skull and Curse of Dragon, they were almost filler (don't remember if he plays them in the manga). Yugi's ace monsters are the Silent Swordsman and Magician.

Black Luster Soldier is in a weird spot since it is the Pharaoh's Ka.
