Less efficient than Doomed Traveler. On the one hand that's good and proper because white should get better weenies than black, but on the other hand this just looks a bit anaemic. I go to the trouble of letting my 0/1 creatures die, and my reward is... a Prickly Boggart?

This was meant to compare directly to Doomed Traveler, but you're right in that it doesn't look very good at all. Not all cards can, of course, but perhaps this deserves to be a 1/1.
