The Great Quake

(You may cast a legendary sorcery only if you control
a legendary creature or planeswalker)
Return all creatures and enchantments to their
owner's hands. Lands your opponents control don't
untap during their controller's next untap step.

Awaken 8—{6}{u}{g}{g}(If you cast this spell for
its awaken cost put eight +1/+1 counters on target
land you control and it becomes a 0/0 elemental in addition to its other types. It's still a land.)
