Heh, I was using a version of this yesterday with -2 Bonds + 2 Water Towers and a switched Pend/Mark setup. Had the same problems you're having it seems; too much I wanted to put in for what I wanted the deck to do. I'd see about getting more early
generation in here; the sooner you can get SoP + an Octopus going, the better. I'm actually a fan of Flooding in here, though that's probably because every other deck I faced in Arena yesterday had Devourers/Pests being spammed in it.
Other improvements I could suggest would likely make the deck larger than 30 cards and situational.
