Settling Pastures

Whenever one or more creatures you
control deal combat damage to a player, tap
all lands that player controls and untap all lands
you control.
"A silent night on the prairie leads to a soft night, but
if there is no obstruction, the winds pick up speed, and
the trees become lifted from their roots. The animals
have nowhere to hide, and the hunters descend upon
the innocent. This, while a tragedy, is the way it must
be."
