so my answer is FAIR. High risk high return. you can survive, you win
You absolutely do not have to wait until turn 10 to use that combo. In fact, I never have.
You can put the first one out on any turn that the zombie hero doesn't leave enough brains to deal with it.
After every update I check to see if this exploit is still working, and I usually pull it off on turn 6 or 7.
the discussion about turn 10 is that, assuming the opponents block meter isn't nearly full - turn 10 is guaranteed death. (you would also need 2 empty lanes tho)
