Metalwork Colossus is a card that people were very excited about when Kaladesh was first previewed. There’s a ton of cheap artifacts and Sanctum of Ugin, so surely there’s a way to just chain Metalwork Colossuses into play, right? The problem with this strategy was Aetherworks Marvel. Not only was Aetherworks Marvel into Ulamog approximately as consistent and significantly more powerful, but the incidental artifact hate made it unreasonable to try being any other artifact deck besides Marvel. With Marvel gone, perhaps it’s time to revisit Metalwork Colossus shenanigans:

Buy This Deck

In addition to all these cheap artifacts, you’ve got Glint-Nest Crane to help you find multiple Colossues to cast, as well as Herald of Anguish and Walking Ballista as a backup. Once you start casting Colossuses, you can just keep sacrificing artifacts to cast Colossus again and again against control decks. Your real problem is going to be aggressive decks that can just attack into Colossus and kill you. Enter Elder Deep-Fiend. This card lets you buy yourself a turn and tap down attackers and blockers alike so that you can get in for lethal on the following turn.

It’s hard to say whether or not this is something you really want to be doing in a format where people can play Heart of Kiran and Scrapheap Scrounger. You don’t really have all the tools you’d want to be able to keep up in the maindeck, which is why you bring in Kozilek's Return and Baral's Expertise out of the sideboard to help you keep pace. However, this deck looks like a ton of fun to play, and will certainly lead to some crazy plays.
