Question

Let's say we had an Espeon with the Ability Synchronize that was holding a Toxic Orb and it became poisoned. Would Synchronize activate and poison the opponent?

Answer 1

No.Synchronize will only pass on status effects to the opponent that caused them, it won't work if you have a flame orb or something like that.

so if say, a Gardevoir were to use trick to switch from a flame orb while it's paralyzed, would it's ability burn the other pokemon as well, or amI just spouting nonsense?
