From a person who plays zombies. Kill the witch. Spell spam them, the are always together anyway. Beware of reapers blade and essence drain. Hit em with range. Hope this helps you a bit.
I know the topic is getting old, but i say this: prevamp your right, but now without shroud, moragen price, mobi price, is harder to win. Edit, OH no swarming from rng units dead fairy and RIP high warlock.
I tried a Zombie deck recently and didn´t like it too much, a lot of good runes were toned down with the revamp, I don´t think it is strong as before
Burn the witch! also, that last line makes me think you are advocating using the random number generator against the enemy...
The single least fun to play against set in the game. Even if you're winning, the match drags on and on and on and just makes me hate the game for allowing such a thing; siphoning any semblance of fun it had left. I really don't get how anyone could like that type of play...or even has the time for it.
And to think, the guy that introduced me to the game was a zombie/attrition player... How the hell am I still here?
