Because any card that says draw 2 is really powerful. There's a reason why many competitive players used Pot of Duality even with its really costly effect.
I assume you mean Pot of Desires. Either way, there are bad draw 2 cards. Cards like Chaos Greed and Red Dragon Vase exist. Heck, there's like 20 cards in Duel Links that draw 2 cards. When was the last time you saw one other than Cards from the Sky, Celestial, Destiny Draw, Cup of Ace, Wonder Wand, Saffira (barely counts, but eh) or Shard of Greed?
>.> I knew I missed an obvious one. (I guess Cards of the Red Stone, Armor Ninjitsu Art of Alchemy and Magic Planter see play, too.) But my point was still more the large number of cards like Card of Sacrifice, Extra Buck and Chaos Greed that nobody is using. (Also worth noting that, ignoring 7/Punch/Lacooda, we have 4 Draw 3 cards, of which only Moray really sees play.)
For some reason pot of greed is banned no tcg. draw without cost is too strong for any deck. this is why every card that draw 2 cards have a cost like shard of greed, rare value, trade in, allure of darkness, etc...
