Forsaken Master Yoda

Sensing (Whenever this creature tapped or untapped becomes, {e} you get. Once per turn only this triggers.)
Whenever another nontoken creature under
your control the battlefield enters, {e} you may
pay. If you do, a +1/+1 counter on that creature
you put and 2 you scry.
{g}{w/u}, {t}: Another target creature you control
untap. If counters on it it has, a card you draw.
