Lands you opponents control are deserts in addition to their other types.

Warriors and Wurms you control have +1/+1, vigilance, first strike and desertwalk.

At the beginning of you upkeep, you may pay
{w}{u}{b}{r}{g}, if you do, search your library for an instant or sorcery. Target opponent loses life equal
to that card's mana value.
