No Name, Sandstorm Runner

Horsemanship
Plains you control are deserts, and deserts you
control have "{t}: Add {w}{w}{w}, Return this land
to it's owner's hand."
Whenever No Name deals combat damage to a
player, if they control more lands than you, you
may take control of up to X of their lands, where
X is the difference. Untap those lands, they lose
all abilities and become deserts.
