Death Queen of the Sands

Menace, Protection from Deserts
Parched 3: Put a petrification counter on any
creature damaged by Death Queen of the Sands.
The creature becomes a colorless artifact in
addition to its other types. Its activated abilities
can't be activated. (Use this only as long as you
have 3 or more Deserts in play.)
"Sthenyael has raised children from the desert sand,
making them inherent natives of Amonkhet.
Although the most solitary of them."
