This is a great deck! I love the colorless-ness! Possibly add Galvanic Juggernaut because of pit trap, and then you could also use it as a blocker once it untaps? Also, Kuldotha Forgemaster?

I like the idea behind this! Not sure if they'd help you out any or not. But maybe add Phyrexian Dreadnoughts, Eater of Dayss, and Torpor Orbs? Phyrexian Dreadnought and Eater of Days are pretty low cost but super powerful artifact creatures that have a nasty draw back coming into play on the battlefield. BUT you can void all of that with Torpor Orb, and that's a few more artifacts to feed your Juggernaut!

Awesome suggestions LegacyCore!!!!

I love the combo with the Torpor Orb. Definitely going to have to add your suggestions!

Lionsheart you should check out my deck Legacy's Dreadnought tell me what ya think ;)

Just piping in to say I love the thematic concept of this deck — I've got a whack of juggernauts, and I'm tempted to open up my own juggernaut-factory. Ram-horned siege engines for the potential win. ( Or at least having a blast cranking out Ramroller s at break-neck speed! )
