This cube is about two weeks old, and all I've done so far is 2 person sealed and mock drafting online. Seems like I'm always short on artifact mana for Wildfire / Upheaval decks. I've considered running the signets, or at least some of them, but it seems inelegant.
I also realize the cube needs lots of work, especially in green and white, but this was more or less from things I have on-hand. I've considered adding a second copy of Wildfire or buying a Burning of Xinye. Probably the former, since I'm considering doing the same thing with Armageddon. Is one copy plus Ember Swallower enough at 360?
You should check out the $2 budget thread that's stacked on these forums. There are a lot of great suggestions for cards that would easily replace some of the cards in your list. Not that your list is really all that bad--I was going in expecting worse cards by the way you described it--but there are certainly cards I wouldn't consider for a 1080 that you're running.
I would play 2 copies of the actual Wildfire effect to help support it, especially if you're gonna be shy of a few of the Tutor effects that smoothes out the archetype. So either 2x Wildfire, or 1 Wildfire & 1 BoX.
