With the Nerubian Egg, board clears are much more difficult. Same goes with the Creepers.

New Zoo activates their Eggs by either Argus or Power Overwhelming to clear your SI:7 or Farseer on Turn 3 since the Egg was played on Turn 2 or Turn 1 + Coin. Miracle has no real plays on Turn 1 and 2 against a Zoo with an Egg and you don't want to waste a one point attack damage against the opponent losing one charge on the blade. So what do you do? Are you sapping the Egg or the 4/4?

And the only way to efficiently remove it is if you can combo the eviscerate, a little hard to do on Turn 4 if you don't have a Backstab. And like I said, usually your Turn 3 minion drop, either a Farseer or an SI:7 will get Soulfired away, leaving no other option to destroy the 4/4 with a spell.

There are other scenarios to deal with since there are different versions of Zoo, some with Void Terrors. How do you deal against these types of Zoos? Many people say Rogue is favored over Zoo, but I feel that can only happen if you have an almost perfect hand to deal with the onslaught since your only card draw are coming from Shivs/FanOfKnives and that is taking up your entire early turns.

The Deathrattles are making this entire matchup a lot more difficult than it used to be and it feels like Zoo has the higher advantage now.

don't devote 5 cards to leeroy combos

add some real minions to stall (eg. senjin)
