***TRIALS RESPONSE***Since you don't have 3 Lobotomizers I assume you can't afford this deck fully upgraded either? If so, I would recommend this (
http://elementscommunity.org/forum/index.php/topic,14533) deck as a baseline. Just removing 2 Lobotomizers would bring you at exactly 30 cards, although you have a much worse chance against decks like Fire Queen or Osiris, it's still profitable to farm fgs with it. You would also stand an even better chance against the easier fgs that don't need the Lobotomizer by drawing the other cards earlier, and never having a dead Lobotomizer in your hand.
So it'll basically look like this:

Other than that it works the same as the thread I linked says, where "really needing early lobotomizer" translates to "you will probably lose". Of course, since you have one, and not no Lobotomizer you might sitll be able to draw one early, it's just less likely.
I'm not entirely sure how this deck works with 0, 1 or 2 Lobotomizers, so if you want a deck that doesn't require any rares and is tried and true I'd recommend using Liquid Antimatter (
http://elementscommunity.org/forum/index.php/topic,17730.msg241141.html#msg241141). It requires a different way of thinking and is good against different kinds of decks. It's win-rate is low but it has the advantage of being cheap, still, it's best to try either out in the trainer first and having spare electrum before you start farming. These decks don't work as your regular decks, and you won't waste electrum in the trainer. In the end, it's best to choose the one that best suits your style, I hope this helps!
