I cast Pot of Greed
Thing is, Pot of Greed doesn't even come close to the kind of card draw you can get in MTG. Try Necropotence on for size.
It's value is still great though because it costs nothing. Every time you draw it you may as well have just drew 3 cards, for absolutely nothing.
If it was actually priced at 0 mana, yes, it would be an unbelievably strong card. It only puts you up 1 in terms of card advantage, but it cycles your deck quickly which is very powerful. Basically a better Gitaxian Probe, minus the hand information. If a card like that existed in Magic, it would be an auto-include in every deck. OTOH if I'm casting a spell to tutor up a card from outside my deck, +1 card advantage is the last thing I'm hunting for at that point. Griselbrand let's me draw seven any time I like as long as I have the life for it. Necropotence or Yawgmoth's Bargain let me draw basically my entire deck under the right circumstances. If I'm looking to storm off or something, that's the kind of card draw I need.
