This post is directed mostly at builders of control decks, but any help is appreciated.
It should be obvious to many that null rod is a very strong hoser in the current environment. Besides locking down the standard artifact mana, it also takes out mindslaver, equipment, isochron scepter, illusionary mask, and Karn/Trike/Pentavus.
As a control player, this is an attractive inclusion as a maindeck hoser that is almost never a dead card. The decks that have used this strategy effectively are usually aggro or aggro-control strategies such as O.Stompy, Fish, and Suicide.
What I have been struggling to do is build a deck that has a more dedicated control strategy, but can still abuse null rods. The problem I’ve had so far is that in order for control to be successful at stopping the early rush of combo and aggro strategies (I’m being ignorantly simplistic on purpose), it often requires early mana acceleration to support large draw spells or tutor chains, or it uses ACC counterspells at the expense of card advantage (FoW) or tempo (Daze). This is problematic, since you don’t want null rod’s effect to be symmetrical, however, you do want to be able to power early broken plays with moxen. Also, please don't suggest Damping Matrix as a solution. Its higher mana cost, and its different effect make it inadequate for my purposes.
Additionally, since Null Rod is often a mana-denial strategy, as a deck builder, I have a tendency to want to reinforce that direction with strip effects, Back to Basics, and the like. While this has long been a strategy of decks such as Keeper and Urphid, it appears to me that (with the exception of Landstill), current control decks have been moving towards large amounts of card draw (Hulk), and efficient finishers (Psychatog, Dryad, Welder-Slaver) as their focus.
One example of some success in this direction is something like Jonathan Patch's deck:

While Null Rod is a metagame call, the deck I have in mind would be something that is more flexible and could be brought to larger events. I'm going post a decklist in a short while, but would like to see what kind of discussion this generates.
