So, it's basically almost a Stone Dragon with an ability? Meh.
Good point. But it still seems balanced to me (maybe I'm wrong).
I'm thinking about proposing some changes to the ability. Smasher looks like it could destroy a random opponent's pillar (after destroyin one yours) and deal some minor damage to the opponent at the same time.
But if you also have a powerful creature... well, it must have something bad I figure.
