Desert lands you control have "{t}: deal 1 damage
to target creature or planeswalker"
Whenever a Desert land card is put into your
graveyard from the battlefield, look at the top card
of your library, if it's a Desert Land card, put it
into your hand.

Planeswalkers have spent much time debating which deserts are more treacherous, those of Tarkir, or
Ahmonkhet. Many more didn't have the chance.
