Cards in a powered Cube tend to fall into three buckets: the "fair" bucket, the "unfair" bucket, and the "broken" bucket
All colors have access to fairly strong artifact ramp, but those artifacts are far more vulnerable to removal than lands
For extra fun, try Eternal Witness, Merciless Executioner, or Acidic Slime
You see the Red enchantment in Commander with a similar approach in mind, as youre looking to do something inherently busted and unfair when resolving the card
But probably rarely, and probably only after a wheel
My list, and any list worth its salt, uses plenty of deck manipulation cards like Sensei's Divining Top to ensure high-cost cards get revealed, dealing maximum damage per turn
