***TRIALS RESPONSE***Ah, devquake. A favorite of mine.
However, this deck is too big. It doesn't have enough stalling to deckout, lacks enough denial for this big, and the damage will be too slow. Thus, I propose this deck turn into a smaller, 30 card version. This is what I would recommend:

This version has the benefits of being slimmer to get better draws and more fluid earth quanta. Five earthquakes and six devourers are typically enough to shut down, and I always opt for earlier devourers over earthquakes. Previously, your deck was producing way too much darkness quanta for what you were using it for. Now, with a decent draw, you'll be getting the right amount. For attackers, I have decided to drop the minor vampires and the lone dragon for only the gargoyles. I've also eliminated the liquid shadows, as this deck is somewhat snug on card space. One steal for a pesky weapon/shield, and if you want you can drop another pend (I prefer 12 for more consistent 2 pend draws) for another utility card (another steal, a dusk mantle, or a nightfall to make your devourers work harder for you). If I dropped a pend, I'd probably go for the dusk mantle.
