I did a search and the only decks I found using this concept were in Deck Help and the Elder Archive. So, here's my version of something I would've thought would be more common.

Since I started, I have upgraded some of the pendulums.

It tends to EM fairly often from what I can tell, but I haven't actually tried to put together stats. It's relatively quick, and I frequently beat out rush decks. The primary strategy is to Fractal a Devourer and fill at least a row and a half with them, maybe two rows. Fill the remaining slots with Minor Vampires.
The Vampire Stilettos are included for obvious reasons, and the nightfalls are for overcoming shields and/or one last major assault to kill an enemy in one more turn rather than 3 more.
I tried Drain Life and Steals, but they don't really help enough to justify themselves. I may go back to Steals though, because Flooding and Thorn Carapace are total death for this deck if you can't shut your opponent down with Devourers first.
Like I said, I'm sure this has been done plenty of times before, but my search turned up little, so here it is. Sorry if it's a dead horse being beaten.
If it's completely unoriginal, anyone have pre-existing stats? It currently seems to work exceptionally well. If I played hard enough, I could probably up a card every hour or so I think? But I play so slowly and infrequently by nature, that I only up 4 or 5 cards a week. No, a super-fast deck will not help with that...I can't play this game that often...I can't play ANY game that often. I have the time, but not the interest. I am THE casual gamer.
