We've started to see artifact-based aggro decks in Legacy in recent weeks. These decks are typically using Ancient Tomb and City of Traitors to power out Arcbound Ravager and Steel Overseer backed up by Chalice of the Void and Trinisphere. That's all well and good, but you lose out on most kinds of defensive interaction and don't have much in the way of resiliency. With so many artifact-themed cards in print, surely there's a way to build this deck so that it has some additional resiliency:

The real strength of this deck over the other artifact stompy decks is that you get to play Blue cards off of a couple of Islands and Seat of the Synods. You lose out on creature lands like Inkmoth Nexus and Blinkmoth Nexus, but Thoughtcast, Daze, and Force of Will are powerful cards in their own right, especially when they are backing up the likes of Master of Etherium. Daze is a little iffy due to your low Island count, but when you get someone with it, you're going to get them pretty good. You also get Ensoul Artifact, which is particularly powerful with Darksteel Citadel.

The big selling point here is The Antiquities War. This card is card advantage plus a win condition, and Enchantments are particularly difficult to interact with in Legacy. Even if your opponent does manage to fight The Antiquities War, you've got Karn, Scion of Urza to back it up and grind out the late game.

This deck seems like a fantastic way to play a proactive, artifact-fueled gameplan without just losing to artifact hate. Karn, Ensoul Artifact, and The Antiquities War give you plenty of outs to crazy hate cards like Stony Silence, Null Rod, and other fringe Legacy sideboard cards. If you're looking for a way to make The Antiquities War happen in Legacy, this might be your best bet.
