You'd start with Reverse Time to slow the enemy's draws down to give you time to get the lockdown in place with Eternity. If they didn't start with a defrag, you'd hugely reduce their chances of getting one -- and if they did land it, you'd just replace the lost Eternity with another and continue putting their creatures back.
Same goes for the energy denial strategy, except you'd just block them from getting anything out in the first place.
Perfect? No. But it would have pretty good chances if the rest of the deck was built to work with it.
Plus some of the immortality setups may be a bit too good, I'm rather hoping something will be done about the strategy. Nova also is a bit too good - as evidenced by the huge number of viable decks that have no pillars at all and just fuel their cards by Novas.
