I have been tinkering with this deck idea since DP came online on the test server, and I can't believe nobody noticed or posted on the boards about these two cards interaction:

Infinity Core + Antimatter

IC provides a constant source of healing since regular elemental build tend to pack a respectable number of allies. In fact, IC itself should be an autoinclude at almost any elemental deck.
Antimatter is a great long-term deck accelerator. It digs into your deck for the card needed while fueling IC.
Obviously, this deck is in its very early development phase, but I give it a try and you'll feel the potential inside. You can discard Bloodthirsty to Antimatter thanks to Xar Modulator.
