anti-rush decks generally consist of good damage block shields... (start with dusk or fog, when you get enough quanta, permafrost or diamond)
a lot of different CC (a lot..)
some sort of healing (generally SoGs for upped decks, unupped decks usually have miracles, GS is good for both upped and unupped)
maybe some quanta denial (usually black holes, as it can heal too)
maybe some hourglasses if the deck is large
PA is suggeslted to protect the shield and other things
lastly, maybe temporary stall cards (sundials, phase shields, that sort of thing)
