Invalidate?

1. against POD do you have to be in combat when pod is cast to invalidate it?
It pod is already cast and u join the battle does it invalidate it?
If u invalidate pod does it remain after u die? Or does the enemy regain pod buff after u die?

2. Does it work against unbending + pod?

1. You must be in combat to activate it, when you expect your opponent to use POD just switch in your invalidate monster.

If POD is already cast joining the battle will NOT invalidate it.

The enemy will not regain POD buff after you die but they can just cast again after you are dead.

2. It works against unbending POD birds.
