I played one guy at a pre-release, and one guy locked down all my attacks with a Balista Squad, I had a Snapper out, a 2/2 for two that can't be targeted if you have no untapped lands, and a Waterfront Bouncer. I top-decked a Silt Crawler, I played it and tapped all my lands and attacked for two... soon my opponent had to block, I killed the squad and went for the kill. This might not happen often, but it did, and won me the game.
I can bet that some decks will be based around bouncing this and attacking with things like Fault Rider. I give it a ****... If the green untapped land cards were better it would be a **** 1/2, and if green could bounce, it would be a *****, because a Fault Rider type deck would have to be 3 colors. That is my 2 cents.
