An Azorius Combo Deck that relies on casting 0 and 1-drop artifacts with Aetherflux Reservoir, ensuring lifegain to blast someone for 50 damage easily. There are many cards to pull out the Reservoir, including Whir of Invention and Glint-Nest Crane's ability. Sram, Senior Edificer can be used to gain a card advantage by casting said artifacts, and Baral's Expertise and Paradoxical Outcome can increase Reservoir's effectiveness by bouncing the 0-drop artifacts back into your hand, only to cast them again. Eventually, your counterspells and removal will gain you at least 50 life, allowing you to oh-so-satisfyingly annihilate your opponent for the win.
In casual playtests, I have been able to kill someone on turn 6, with 20+ life to spare, too. This deck only falls to extremely aggressive aggro decks - the only deck that I've played and lost to is a modern exalted aggro. Mardu Vehicles? Check. Green/Black Constrictor? Beat it. Blue/White Flash? Demolished. Grixis Control? It was tough (18 turns), but beat it, too. The only thing to watch out for is when you're about to pay 50 life. Always make sure that you have at least 20 to spare, as you opponent may destroy a Reservoir, or Disallow it. I haven't taken this deck to FNM yet, but as soon as I do, I will post the results.
NOTE: This is a variant of Bai Hualin's Pro Tour Aether Revolt deck, which revolves around the same mechanic and includes many of the same cards listed here.
EDIT: I went to FNM with this deck last week, and wound up finishing 2-2, falling both times to Rakdos Madness Vampires (of all decks, right?). My two wins were 2-0 against Black-Green Constrictor, and 2-1 against Red-White Vehicles. Overall, I would say this deck isn't FNM-worthy, but more of something fun to unleash on your friends during casual Magic or small tournaments.
