My concern would be that, if we considered Meat Market in comparison to Treasury, you'd basically be able to buy Province every turn as soon as you played 4 to 5 individual copies of them (as they align themselves, and getting +4$ a turn before considering your hand means that your average hand just has to be worth 4$). Unlike Treasury, this never stops. It's why I was skeptical of GendoIkari's assertion that Nordic Village would be stronger than Meat Market. At the very least, you need other cards to make that work. For Meat Market, buy 4 and then buy Provinces whenever you can, or more Meat Markets/Gold when you can't.
It's also why I said before that I felt Nordic Village was the more interesting card to me.
I feel like a simple Peddler that makes other players take their - might be too strong for , even without the season ability of playing one multiple times per shuffle.
There's something to this. Even without the Token, Viking Ship is a Peddler+, which is at least worth 4$. Relic gives out a token and is a Silver+, so judging from that comparison alone it might in fact be too strong. My experience with Empires is a bit lacking, though, so I don't know how good Relic is usually considered to be - and of course it uses the card token. I mean, Bridge Troll isn't a straight Bridge+ either.

I think I'll first playtest Nordic Village (because even though Walled Village TRIES to do something similar, it usually fails miserably) and Meat Market, and then possibly consider Viking Ship or (if Meat Market seems too good) instead try a shuffle-Meat Market (and a new name, probably). Fish Market, maybe? I considered "Whalers" for a while, but man, it's absolutely impossible to find pictures for that... Ah well.
