Gear Moon

Nonbasic lands are "Steam-Powered" in addition to their other names. They have "{t}: Add {c}{c}{c} to your mana pool. Spend this mana only to cast artifact spells."
We've got a steampunk revolution.
We're tired of all your so-called evolution.
Magics and sorceries only make us sick.
Don't ask us why; that's how we get our kicks.
