Enveloping mists

Kicker {u} or {2}
Tap each non-spirit creature you don't control.
If this spell was kicked, those creatures don't
untap during their controllers' next untap step.
Night falls, and a mist settles over Innistrad. Where
there would usually be screams, blood, and death,
there is only a seemingly gentle mist, enveloping even
the night itself.
