2 generic mana , tap : Tap all other artifacts. They don't untap during their controllers' untap steps for as long as this artifact remains tapped.
Success is largely a matter of knowing which lever to pull.

Note that you can't choose to leave this card tapped during your untap step (unless some other effect says so).

Only the artifacts that it tried to tap when the ability resolved are prevented from untapping. Artifacts that enter after that or permanents that become artifacts after that are not affected.
