Here is my take on an Earth deck, which doesn't rely on shriekers and graboids.
Here's the deck

You can put your own spin on this deck, such as taking out the PAs if you know you won't be going against anything that threatens your shields. Taking out the granite skin if you're going against a rush. Replacing granite skin with shriekers (Although, that defeats the point of the deck, since it's specifically designed to not have shriekers in it.) This deck would need a couple more towers to support dragons, so those aren't recommended in place of shriekers. You can also throw in a gavel or two, make it 32 card and it doesn't hurt it.
How to use the deck:
Fairly straight forward, but here are some general tips. First, if you have two antilons, play those two creatures over a steel golem, as that's 2 extra damage; unless you think your opponent will kill the antilons. (Mono-aether deck with lighting, for example.) Granite skin acts as a last minute save mid to late game. Protect artifacts go with the shields, if you're going against an earth deck, with quicksand they can be used on the towers.
Stats:
AI3- 11-0 No problems with it, just a bit slow, so not ideal for farming.
T50- 4-2
AI5 3-3 Loses as much as it wins, really just depends on which deck you end up going against.
