Because if you have 40 cards in a deck, and one of them is pot of greed, leaving 39 cards, then you use it and draw 2, which leaves 37. By including 1 card you remove 3 from your deck, giving you better chance to get cards you want. and thats just 1 pot of greed, not 3
who ever draws it first is most likely going to win
I played someone within the last hour (1/10/19 @ around 3 am) who used Pot of Greed in their deck. I don't recall their username, but if I duel them again I'll be sure to report it. I thought Pot of Greed became legal again. I was like "Holy frack!" I mean Monster Reborn is now legal so I really don't see why Pot of Greed is. Both cards can be easily stopped (magic hammer, magic drain, dark bribe[even thought that one kinda just cuts pot of greed in half lol] ) but still...ya know where I'm going with this...or at least I hope so. And I hope somewhere Konami sees this lol
This card is still more overpowered than spellbook (even spellbook of judgment). Reason? Splashable in literally every single deck. There's no deck in yugioh that won't benefit from having a pot of greed in their deck. Which means it can be used to boost broken decks to be even more broken (including your spellbook deck).
What is the point everyone knows what this card does but no one can use it
