Iron Man, Master of Machines artifacts

Iron Man, Master of Machines leads a mono-blue "affinity" deck: every artifact you control gives him +1/+0, and whenever he attacks, if an artifact entered the battlefield under your control that turn, you draw a card. The plan is to flood the board with cheap artifacts (Chromatic Star, Meteorite, Prophetic Prism, Ornithopter of Paradise, Cathodion) to make Iron Man huge and reliably trigger his draw, while cost reducers like Etherium Sculptor, Foundry Inspector, and Shuri, Wakandan Inventor accelerate the flood.

Card advantage is backed by Padeem, Consul of Innovation (draws if you control the artifact with greatest mana value), Jhoira, Weatherlight Captain (draws for each historic spell cast), and Armor Wars, whose first chapter draws cards equal to artifacts controlled. Urza, Lord High Artificer converts artifacts into blue mana and creates a Construct that scales with artifact count; Isochron Scepter with Dramatic Reversal imprinted can generate explosive mana by untapping all nonland permanents. Emry, Lurker of the Loch and Academy Ruins recur artifacts from the graveyard.

Main win conditions: repeated attacks from an ever-growing Iron Man with guaranteed card draw; Skysovereign, Consul Flagship and Kappa Cannoneer as hard-to-block evasive threats; Mechanized Production as an alternate instant-win plan by copying a cheap artifact eight times.

Weaknesses: the deck is vulnerable to board wipes and artifact hate (ironically including its own Armor Wars against you), has little protection beyond Swiftfoot Boots and Padeem, and relies heavily on an early low curve—if Iron Man is removed or artifacts get swept, card advantage collapses quickly.
