What about Hidden Herd? Yeah, it sucks in the late game. You want to win (or at least, deal significant amounts of damage to your opponent by attacking with creatures) in the early game. And yeah, a 3/3 on the first turn could help with that.

Drawbacks:

- If your opponent draws the one basic land they have in their deck, they could delay the Herd by a turn -- how often this happens and how much it sucks would likely have to be tested.

- Since the advent of Dragon Stompy, people have been playing more basic lands. So maybe this isn't the right time.
