We cannot talk about banned cards without mentioning this bad boy. The mere mention of this card makes players around the world rage-quit so hard they break a table. Yata Gurasu has been forbidden for years and for good reason. Yata Gurasu is a spirit monster who, on getting a
clean hit at its opponent's Life Points, will stop them from drawing a card on their next turn. Not only this but, as it is spirit-type, will return to its owner's hand at the end of the turn. This means that the opponent is stuck with the monsters, spells etc that it already has available. This, combined with one of your traps and spells could render the opponent's play to dust in seconds if they do not have the counter monster and attack. This is the power of the infamous Yata-Lock.
