Ward-Sacrifice a land

Non-basic lands you control and non-basic lands you own and are not on the battlefield are Deserts in addition to their other types.

Sacrifice a land: Creatures you control gain Hexproof and "This creature can't be blocked" until the end of the turn.

At the beginning of your end step, each opponent loses X life and you gain X life, where X equals the number of Deserts in your graveyard.
