Would try Exploud, except I have none whatsoever. The deck I'm using at the moment is pretty much Hippo/Ninetales/ Sableye- It sounds bad, but the drawpower is phenomenal. Roast reveal, engineer's and impersonating an engineer's in the same turn (not impossible) is just incredible, not to mention save sanding with a dce already attached that sets up for a good groundquake. I run quite a few energy so that combo's rarely difficult to pull off.
I will try Lost Remover to improve the 'Gar matchups (both vile and lost), along with the odd g-dos matchup too. As far as normal techs are concerned, I can't think of any other than Exploud (which I have none of) or Ambipom g. I once considered Breloom sv as a nice tech.

I did test 'Tomb as a starter but Sableye is far better for this deck- As odd as it sounds, Hippo needs speed in the combo I'm using. Plus, impersonating an engineer's (or collector) is my ideal start.
