Morass Wader

Vigilance
When Morass Wader enters the battlefield, you
may search your library for a basic land card,
reveal it, and put it into your hand. If you do,
shuffle your library.

Each small wetland pond is fiercely defended by a
single dominant male Morass Wader. In case of a territorial dispute, males lash out at each other with
their long, whiplike tales.
