Simple. It doesn't clog up your hand. It's designed to have several out to do surprise burst damage. The key part being surprise. No one would expect 3 creatures to come out of nowhere when you've got an empty hand or very little quanta.
One other strategy would be to put out several, and then play nightfall. The added +2/+1 would break stealth, and then use Pounce on as many as you had the quanta for (depending on what the final version would be)
