I use a fairly similar deck when I spin Seism at the oracle, but with Hope. Being completely unreliant on pillars means his quicksands just sit in hand useless. It's not the best FG counter by any means, but it's around 50%. (I don't have my notes at work here, but I think I'm 3-3 against Seism with it)
Also, have you tried using feral bond? Helps with getting those EMs, and with mitosis, it's got a fair amount of healing behind it.
