Well, don't the dominants and artifacts take care of that? Also Women as Snares is there to take them out. Holy Grail might convert one. Ark of the Covenant could discard one, and then there is AOTL and Grapes. Elijah's Mantle gives my guys +2/+2, and Jepthah can take out 2 evil chracters. I could add Three Nails too I suppose.
Someone would have to have a LOT of big guys to stop this, I would think.
