Loot
Treasure-Reaction
Cost: $5
If this is the first time you played Loot this turn, it's worth $3, otherwise it's worth $0.
-------------
When another player gains a Gold, you may reveal this from your hand. If you do, they gain a Loot instead.
This is sort of an anti-Fool's Gold, indeed borrowing the type and language directly from it. It was inspired by a comment made by Axxle on another thread about changing the wording on gold. It has an interesting (hopefully not bad!) reaction that lets you sabotage your opponents...maybe. There's really no reason NOT to pick one of these up, it's a cheap gold if you just have one, and it may give you a chance to wreck your opponent. But if your opponent gets one and you start racking these up, it can cause real issues when they collide. Not only is it a dead card, but it's a worthless treasure, which hurts. Interesting interactions with gold gainers like tunnel, explorer, and especially governor.
I've done absolutely zero playtesting since the idea only came to me a half hour ago. Criticize away!
Btw, not a big fan of the name on this one, so if you have any better suggestions...
