I noticed that you tried launching the deck once before, but without success - raised just under €1,200 on a €8,500 goal. Aside from the reduced goal of €6,500 this project looks to be exactly the same, and you've raised nearly the same amount of money so far.
This is for the original project. It appears to have run for four days before you cancelled it.
Why cancel after only four days? Sure, funding was nearly flat after day one, but that's fairly common and there are ways to overcome it. This place is one of them - a place where you can reach a card-collecting audience. But it looks like you need more than just card collectors. Where else have you been advertising it?
The theme you've chosen might be what's making this a little difficult, I suspect. The idea of showing elements of different cultures is interesting, but the four cultures you've chosen - what links them, if anything? Finding people interested in one of the four cultures might not be enough to attract them to buy the deck, since it only covers their point of interest on 25% of the cards.
