Obviously, things with 'charge counter' on the card might help. The Mirrodin cards like Power Conduit and Coretapper are nice, but the best interaction by far is... Dismantle! Effectively, it reads: Double the counters on Darksteel Reactor by spending 2R. (If you doubt this, see Saturday School #63, wherein the official MTG site agrees with this claim.) Is there any other card that goes so well? Please Reply.
