From what I see, both Daxx and Scaredgirl have different views of the same card. By view, I don't mean an opinion, but I mean a way that they look at it.
For Daxx, making it draw only one card would give you a two card advantage in terms of drawing, since you'll draw the card for the turn, and then draw another for playing it. If you put six of these into a 30 card deck, then drawing one would pretty much be like losing 1 time quanta on the turn to have your deck size reduced by 1. So, the deck would, in essence, be only 24 cards, which gives the user a HUGE card advantage in terms of speed. However, with a larger deck, leaving the card out would be the same as playing it, since you only draw one card.
With Scaredgirl, she's seeing it as having a card advantage with larger decks. Drawing two cards means that you draw the card you would've drawn if not for the draw card spell, and then you draw another one, which is the prime advantage. Indeed it's standard in many TCG games.
Brainstorm, from Magic: "Draw three cards, then put two cards back on top of the deck" for only one mana. Sirum Visions: "Draw a card, then look at the top two cards of your deck and put one or both on top or bottom of the deck in any order" for one mana. It's a viable card, though I do think that if something like that WERE released, we would need many more cards, so that there are new strategies, and the advantage would be less skewed.
