This card's drain shouldn't be have an effect if the target has dimshields up. If they physically cannot hit, how would they drain? It doesn't make sense from a flavor standpoint, and is plain infuriating in any FG deck that needs dimshields.
I LOVE this card. It provides a source for death quantum as well as a denial strategy for your opponent. I usually use it in a death/earth/aether combo.
using fractal on these things is hilarious.i tested out a devourer, fractal and emapthic bond (just got a mark) deck and i got this hilarious result (http://www.screenshotdumpster.com/view/m7Gbd57018/funny_devourer)i did 88 damage with one drain life (click on the image to see it larger)
