Ahri, the Nine-Tailed Fox

Whenever you cast an instant or sorcery spell,
you may pay {1}. If you do, until end of turn,
Ahri gains hexproof if the spell is green, and
she gains first strike and trample if it's red.
Then, draw a card for each permanent you
control that you don't own if it's blue.
Ultimate — {g}{u}{r}, {t}: Gain control of target
creature or planeswalker until Ahri leaves the battlefield.
