Etherium Sculptor nets you a lot of mana once you play this. It also allows you to play KCI on turn 3.
Krark-Clan Ironworks (KCI) will grow you mana to be able to cast practically everything in your deck.Tutor with Reshape for any missing pieces.
Codex Shredder is there to either mill yourself and get milled cards back with Open the Vaults or to get a Faith's Reward / Open the Vaults back from the graveyard to reuse it
Ichor Wellsprings a two-drop double cantrip. (most of the time they'll be one-drop with Etherium Sculptor or a free card with the KCI)
Thoughtcast Gitaxian Probe basic one drop cantrips.
Brainstorm is a utility cantrip. Use it with shuffling abilities (Reshape or Ghost Quarter) to shuffle unwanted cards away, or use Codex shredder to put it into the grave to revive later with [[Open the Vaults i.e. Lotus Bloom
Emrakul, the Aeons Torn and Banefire are your win-cons.
To win with emrakul, this is what I do. You'll need your board of artifacts with at least one codex shredder. So, to get started, hard cast Emrakul from you hand with mana you build up with KCI, and return all artifacts to your field, pass the turn and attack, then sacrifice it to KCI, Since it hits the graveyard, its shuffle ability triggers. Respond to that with a Codex Shredder and return Emrakul to your hand, letting the shuffling resolve, then cast it again, passing the turn and attacking once again (don't forget to revive your artifact just in case they do anything to counter or oppose you). Repeat until you're able to get hits in.
