I really like both decks a lot. I think they could do some things to make them a little better and a little less inky. So much ink will have an impact on the handling. Moving the Indices out just a touch would help too, but I'm sure everyone knew I'd say that anyway.
The problem with this campaign isn't the cards though, it's the pledge tiers. If the campaign doesn't make it, I think it'll be because of that. The decks are wonderful. If you don't want a brick, best bet is to get as near to a $10 or $20 pledge slot as possible and add on what you like from there. You'll end up saving a couple bucks. More work for them sure, you have to list it all after the campaign but they kinda did it to themselves. Example of my current pledge $80 for 6 decks, 1 collectors box, and 1 ceramic chip. Best I could do if I didn't have an EB and get the same is $82 by taking a very low amount pledge again and adding on. If I use their six deck tier I'm in for $86 instead or $82 or my current $80. Six bucks is a nice sit down lunch at some of the local restaurants here, including a beverage. I like lunch, so yea those six bucks matter to me.
Always a bad idea to charge a premium of a few bucks per teir for the ease of hitting a pledge tier and leaving it. It's Kickstarter and regardless of silly head comments that show up pretty frequently from passion and lack of patience, most KS backers aren't stupid. Tiers like this can keep people from backing it at all.
