text: If Nadu leaves the battlefield and returns to the battlefield in the same turn, or if Nadu leaves and another Nadu appears, the triggered ability granted by the new one is different than the triggered ability granted by the old one. The one granted by the new Nadu may trigger twice for each creature you control, even if the ability granted by the old Nadu already triggered twice for those creatures that turn. (Note that creatures you control won't have the ability granted by the old one anymore, and if you control multiple Nadus, you won't have the opportunity to take actions before the "legend rule" gets you down to one Nadu.)
