Actually, I'm not misreading. Here's my thought process:
Decks get more powerful and consistent the fewer cards they contain, since you can get to your most powerful cards sooner. This is true for most CCGs. Having card draw in your deck is massively powerful, as we know (imagine your rainbow without any, for example). Cheap card draw is even more powerful. That card, as written, allows you to draw three cards for the cost of one draw and a single time quantum. Regardless that it's single use, you could stick six of them in virtually any deck of 30 along with a Mark of Time, and go to town.
