It's a mono-earth list designed around a simple concept: I don't like taking damage, so what if I just don't?
The ideal setup is and three copies of . Then you start popping down defensive minions and artifacts, essentially preventing any damage. Something like being held by with on the field is nasty. Honestly just having WH carrying the amulet while or and him sit in a Gnome Hollow would be busted.
The deck is relatively vulnerable to but Kingdom can mitigate that somewhat. You're not running anything over 4 mana, so you can afford to sit back once you have at least a partial setup, and only drop sites when you have one that's advantageous. If your opponent drops on you before you have a lot of minion-based defenses set up, you are screwed, so try to avoid that, or hold in hand your to push it away if needed.
One option to keep damage low is replacing with to prevent lightning bolts and other direct damage spells from doing anything to your important minions. Keep a sitting under the tree with maidens or the bannerman nearby and he should hold your line from the skies.
Also a possible trade: swapping the bosk trolls for which have higher output for mana that's still under 4. Maybe even . My only reason for running trolls over them is that the trolls are common sense targets, and you're not running any removal in this version of the deck, so tutoring for chump blockers is a major benefit.
