I made a small (not so minor) tweak. After I completed my towers, I made my mark into and added one feral bond. Helps with poison and adds a hundred coins for EMs.
2 more SoGs worked too against Scorpio, but with bond and life mark, the stability of the deck is getting low. You cant count on the only bond everytime ur facing him.
About EM .. with unionruler's original version, this deck has already about 60%-70% EM rate in a long run.
Another thing: your win rate against Seism would decrease.
