I thought I was being original when I came up with the deck in the OP on my own...go figure.
Anyways, I have noticed that for PVP with this deck, you need healing, so I play with the below:
744 744 744 744 744 744 744 744 744 744 744 74c 74c 74c 74c 74c 74f 74f 74f 74f 74i 74i 74i 74i 74i 7n2 7n2 7n2 7n2 7n2
The Titans are still susceptible to mutation though, which is a key weakness. I am still toying with the idea of this deck but for now, it seem I have hit a road-block and don't know where to go from here. Maybe swapping out a few of the towers for pendulums and making the mark Aether and using Quints would be a good route...
Thoughts?
