Veil of Desolation

As an additional cost to cast Veil of Desolation,
exile X cards from your graveyard.
When Veil of Desolation enters the battlefield,
each opponent sacrifices a land for each card
exiled from your graveyard to cast it.
Players can't play more than one land each turn.
"The desolation spreads, devouring all that was once
lush and thriving. Let their lands crumble as their
hopes fade."
