I dislike the new Igloo as it is vulnerable to handsize attacks. I also don't consider the old one to have been overpowered. Terminal space is usually limited so you have to think hard about whether that extra card is really worth the action.
The new one is a bit stronger unless there's a handsize attack, so there's that!
Here's a simpler non-reserve version of Sleigh, you can't save this up for next turn so it's a little weaker but it seems worth the simpler wording.
And here's a nerfed Rediscover. It was pretty obviously overpowered on reflection, not quite sure what I was thinking!
You need to build up a bit before you can use it and it gets harder and harder to call multiples in one turn as you trash cards from play.
And a couple of new reserves:
Gatherer:Counting House and Harbinger type things always get flak for not working if the discard is empty, so I thought something looking at the discard was a good fit for a reserve effect. It gives a Coin token that you can save for the big turn when you topdeck 2 things. Is this too weak? Would it be op with +1 Action?
Spelunkers:I've had this discard 3 to gain a Gold to hand thing floating around for a while, thought I'd try it on a reserve. Too boring? I like that it's tricky to incorporate in an engine because you have to discard at the start of turn. Probably would have to make sure it isn't broken in big money I guess, I doubt it is though. Seems really good to open with so I costed it at $5, is that reasonable?
