Pentavus, its a bit expensive, but if you get it out there, with constant increase in counters, then you have a limitless army or 1/1 flyers that can also be beefed up by steel overseer simultaniously.Arent artifacts just the greatest thing ever? :D

I feel like this wants to be u/g. Counter and bounce is much more effective removal than fight in modern. Also with blue, you could probably drop the serum tanks since you should be able to play enough cantrips.

Using blue was a good call so I made a blue version of this deck Artifacts + Proliferate = Win.

No Arcbound Ravager ?

Arcbound Ravager is awesome and perfect but he is quite pricy. Eventually ill add him I think but for now I'll keep him in the maybeboard.

this deck is pretty modular.

Ruins of Oran-Rief seems good in here

Thanks I'm gonna use that.

No problem

looks sick man, im gonna build this !but ill splash white for removal and tempered steelalso instill energie to make it faster and more aggro

Instead of Arcbound Worker you can put Animation Module. Same mana cost but you can tap 1 for each permanent you put the counters on in order to create a 1/1 colorless Servo artifact creature token.
