Rulings
-
If an opponent attacks more than one planeswalker you control, the last ability of Oath of Kaya triggers once for each of those attacked planeswalkers.
-
If the target is an illegal target by the time the first ability of Oath of Kaya tries to resolve, the ability doesn’t resolve. You won’t gain 3 life.
