Sables, Farce of the Mirage

Whenever one or more creatures you control deal
combat damage to a player you may exile target
land, then return it to the battlefield tapped under
its owners control. If a Desert entered under your
control this way, untap it.

Landfall — Whenever a land enters under your
control, target player loses 2 life and you gain 2 life.

"These respites in the desert are always wonderful,
but never real."
