I found this article from Kstube from 2010. Now we're in 2020 and with a friend we thought "why not build an updated version?"
The twobert version of my artifact cube for 2 to 4 players has become my main artifact cube.
Special rule
Everybody gets to add up to 3 artifact lands of any color combination of color in their deck.
Cube curating guidelines
Cards are divided between 5 categories: actual artifacts, artifact or equipment is mentionned in the textbox, strong synegies (for example hardened scales), fixlands and support cards.
Support cards must not represent more that 7% of the cube (12 cards).
White is mostly the aggressive color. A WW equipment deck notably is supported. Control support is also provided by white.
Blue has tempo and ramp as well as a lot of value.
Black is relatively aggressive with midrange threats.
Red is very aggressive and provides a sacrifice theme. This color can disrupt artifacts.
Green is the main hate color. Artifact destruction is very present. It also pairs well with modular and +1/+1 counters with hardened scales and Rishkar, Peema Renegade.
