I've been playing this deck for a couple of days and found an extra tower or two helped without hurting, I swapped a tower in and took a sundial out. I'm also using un-upgraded dials and I have noticed them getting deflagged regularly, but they've always either bought me enough time or just not shown up at all until the end game when I want my mutants to be attacking. Oh, and the OTYs have a nasty habit of being buried at the bottom of my deck.
Scorpio has my number, though!
I'm thinking on adding a protect artifact and/or another pulverizer, to help on Seism and theives. I might mess with an eternity if I had one. Boo...
