Shoretrooper

Vigilance, Reach
When Shoretrooper enters the battlefield, you may exile target nonland permanent an opponent controls with mana value 4 or less until Shoretrooper leaves the battlefield.
Whenever Shoretrooper attacks, you may look at the top card of your library. If it's a land, you may reveal it and put it onto the battlefield. Other Troopers you control get +1/+0 as long as Shoretrooper is tapped.
