Evening's Respite

Whenever a creature attacks and becomes tapped
this way, you may have it not untap during it's
controller's next untap step. If you do, the next
time it untaps, it gets +2/+0 and gains first strike
and trample until end of turn.
{1}{r}{w}, {t}: Create a 1/1 white Human creature
token.
Nothing like oversleeping to get you ready for a fight. Tomorrow.
