Hiphagix, Desert Ruler

Vigilance, trample, afflict X, where X is the
number of Deserts on the battlefield.
Whenever Hiphagix attacks and isn't blocked,
you may search your library for a Desert card,
reveal it, and put it onto the battlefield. Then, if
you control 6 or more Deserts with different
names, you may create a 5/5 green Wurm
creature token.
With the Hekma destroyed, only those who live below
the dunes survived.
