It takes a bit of grinding to put the Elite version of the deck together, but it's worth it.
A few words on use: Getting at least 3 Quinted Vampires, Eclipse, Improved Dusk, and Electrocutor on the field quickly will assure you victory and Elemental Mastery 9 out of 10 times. Getting all 6 of your Vampires on the field and Quinted will allow you to suck your opponent's HP dry in short order. Be cautious when dealing with decks that make use of Thorn Carapace/Spine Carapace or Fire Shield/Fire Buckler, however. If possible, try to save at least one of your Siphon Life cards for later in the game after you've built up a large enough reserve of Darkness Quantum and use it soften up your opponents HP for the final blow.
