This card is maindecked in a few of my decks, and one of the ultimate sideboard cards when I go to Legacy. The best way I've found to not take the shaft from this yourself is to have a Countering, destroying, cost reducing or bouncing Permanent; Counterbalance, Mundungu, Tradewind Rider, Avatar of Woe, Grand Arbiter Augstine IV, Crackleburr, etc.

I know its a good counter for counter spells but what about patron wizard what do you do on that?? If you have an idea that cost less then tree mana put it down on this same card

City of Solitude for the rest of us... hurts reactive/counterspell decks, so if these are a threat, stock up on these...

Though serving no MAJOR purpose, a Defense Grid can be used in agressive and Burn decks MOST effectively. Because these decks drop hands fast, and every bit of damage counts, 4 Defense Grids in a Burn or Agressive deck aren't a bad idea when counterspells are running amuk.
