Too conditional to be worth playing. How about instead:
"Negates the effect of opponent's last turn on his wall."

Strange card.. only to long mode and only as reaction on two rares - Laputa and Dwarven fortress.. theoretically after magic barrier played with 211 gems and less than 100 wall... I think there isn't other way to raise wall by more than 200 in one turn...

That's why it's a zero cost uncommon that wins a game instantly!!!

PS. Seriously, I don't expect this to be implemented :P

I'm really not a fan of this kind of card.
It will either be completely useless all game or be ridiculously overpowered once. I can't imagine anything more frustrating than getting 300 wall and 280 tower from Laputa, then losing instantly, through no real fault of my own.
