@sygilber: Well, you could play this on an opponent's creature, but it doesn't benefit you. Spirit link has an ability that gives "you" life, whereas Quicksilver Dagger grants the creature an ability that states that "you" draw a card. On Spirit Link, the you refers to the controller of Spirit Link, since the ability is on Spirit Link and not the creature. Here, since the ability is being granted to the creature, only that creature's controller can activate it and when they do, they draw a card.
The only auras that have their own tap abilities (that don't say "Enchanted creature has...") are in Future Sight (see Flowstone Embrace), and those presumably haven't been expanded on because it is potentially confusing. The aura that you are looking for, that you can use to tap opponent's creatures, is Second Wind from that set.

An excellent card for a "Pinball"-style deck.

I'd tap that. Then I'd get a card.

I would rather use Curiosity and Psionic Gift/Hermetic Study. The draw is secondary. You throw this on your Morphling late game so you can protect it from getting bolted, or on your Horseshoe Crab early on.

Turning a guy into a Prodigal Sorcerer and drawing a card is pretty gross...nice enchantment for the cost.

Horseshoe Crab enchanted by Quicksilver Dagger, with a Niv-Mizzet, the Firemind is just oh so fun.
