Ahri, Nine-Tailed Spirit Fox

Flash
Ahri doesn't untap during the untap step.
{w/u}{w/u}, {t}: Gain control of target creature while
Ahri remains tapped. When Ahri becomes
untapped, destroy that creature and put 3
fox-fire counters on her.
{u/r}{u/r}, {ut}: Return Ahri to her owners hand.
Remove a fox-fire counter: Ahri gains wither
until the end of turn and deals 1 damage to target
creature or player.
