Desert Warfare

Whenever you sacrifice a Desert and whenever a
Desert card is put into your graveyard from your
hand or library, put that card onto the battlefield
under your control at the beginning of your next
end step. At the beginning of combat on your turn,
if you control five or more Deserts, create that many
1/1 red, green, and white Sand Warrior creature
tokens. They gain haste.

"...here we need desert power."-Duke Leto Atreides
