Dak-Shal, God of Sand

At the beginning of your upkeep, put a +1/+1
counter on target Desert.
Deserts you control are 1/1 Elemental creatures
that have indestructible and haste and are all
colors. They are still lands.
{4},{t}: Search your library for a Desert land card,
put it onto the battlefield tapped, then shuffle
your library. Activate only as a sorcery.
