Suddenly, fat decks and extremely fast (fire) mono rushes.
Seriously, even unupped, at the cost of 3 quanta, this can fit into anything. A mono life deck, a mono water, mono time. 3 quanta for 2 card draw is way more than worth it. Precogs can make a 30 card deck seem like 24, this can make a 30 card deck seem like 18 or 12.
