Why do most card games only allow 4 copies of a card?

I am interested in making a card game for the sake of passing the time and I notice that in several games such as the World of Warcraft TCG and Magic: the Gathering, only four copies of a card are allowed. I know the idea of restricting overflow of one type of card plays a part in this, but why is the number four? I think it’s 3 in the Yu-Gi-Oh! game but I’m not sure.
Just wondering if anyone could offer insight into this. Thanks!

Let’s say we’re playing a game of "I Declare War". We shuffle and deal the cards. Let’s say hypothetically, I get all 4 aces, all 4 kings, all 4 queens, and all 4 Jacks. How soon do you think it will take me to win this game? I’ve got the highest 16 cards out of 52, the odds are stacked against you. When you play strategical games like Yu-Gi-Oh and M:TG, it helps to know that someone has won because they have outmaneuvered you and not because they had better cards than you…
Yu-Gi-Oh only allows each card to be a maximum 7.5% of a deck. With numbers that small, it keeps gameplay competitive.
Because then everyone would put in the strongest cards over and over again. Not very fun if you think about it.
