Stilgar, Naib of Sietch Tabr

Wurms you control get +2/+2 and have trample.

{7}{g}, {t}: Create a 4/4 green Wurm creature token. This ability costs {x} less to activate, where X is the greatest power among Wurms you control.

Stilgar had been transformed from the Fremen naib to
a creature of the Lisan al-Gaib, a receptacle for awe and obedience. It was a lessening of the man, and
Paul felt the ghost-wind of the jihad in it.
