How about a "vanish" card where playing it would erase any trace of you being in a territory and leave it with the original number of armies in a neutral?

Thoughts?

Not that different from a Blockade card. Just set it to an appropriate number for your game, and you`re good to go!

I`ve definitely used this strategy in games before.

Would it revert to neutral? Or would you still control it and it just appears neutral to opposition?

Poireau, in most games that is not possible. Standard blockade is 3.51 meaning 4 is the minimum value. Also they're typically too valuable to waste like that

I like the idea. If you made it so each card had like had a set amount of territories you could neutralize with it, that would be even cooler.
