Hello, I am in a ladder game right now were I want to use blockade card.
MY QUESTION:
What if the territory that I have blockaded is captured, but then in that exact turn I re-capture the territory; will the blockade card still affect the territory?

Thanks Dodo

It will work and ive tested it. your safe as long as the territory is in your control at the end of the turn

just ask your opponent not to attack that territory, that way you'll be sure.

warflow, why would your opponent listen to his enemie?

I think warflow means reverse physicology.
