Well, I've slowly started to create a little expansion. Few days ago I've given amulets to your opinion, now time for the 'different' moat.
Force barrier (Action - Reaction) 4$
+ 1 action
Choose one:
Draw until you have 5 cards in your hand; or put this card on top of your deck.
---
When another player plays an Attack card, you may reveal this from your hand and discard a card from your hand. If you do, you're unaffected by that Attack.
First of all, I've been thinking about a reaction card, that each turn get's back to your turn. I realized, that it would probably end up like alchemist, that makes you unattainable for enemy's attacks. That would suck. Then I thought about a reaction, that protects you, but only from a few attacks. By combining both of those, came the Force barrier.
So what does it really do? It protects you from 4 attacks while having it in your hand. Or, in case of Torturer chains, even from more. It makes you decide - is this attack worth revealing my Barrier? It work like a cellar. Force barrier, gold, 3 estates and 3 spies incoming? Why not to discard the estates?
Ok, it came to your turn. If there were many attack this turn (4 or more), you can simply start with a new hand. If there were not, you can topdeck the barrier and use it next turn. And when there were only one or two attack? Than you have to decide again what would be better.
I've been thinking about setting Barrier aside to draw it and 4 cards next turn, but I thought that top-decking it would be more fun. If you have a terminal drawer and no more actions, than topdecking simply gives you nothing.
I like this reaction for it's flexibility. It's not the MOAT!, you have to.. MOAT!, I play wi... MOAT!. It's a card that makes you decide during each attack and than decide when it comes to your turn.
What do you think of this one? Is the cost ok? Do you think it would be possible to play with it?
