I decided not to collect full series because they're a money pit, but I am collecting all SP and cats, and I have all of them from Series 1 & 2 so far.
I've got two cards on the way from ebay and then I will be done (two of my trades here never showed up and I decided to just get it over with and buy replacements). While I'm not happy about the delay in the US for series 2....to be honest I'm kind of glad for the break from collecting!
I was planning to do something similar; collect all of the cats, special characters, and any that I think is cute (but...there are too many of them). Once I had some of the cards though, I changed my mind and wanted to collect them all ><. As I keep playing the game and summoning villagers using the cards, I find more villagers I like or want the card so I can summon them and use them to follow a certain theme.
Now, I have about ten more cards in series one to get and the limited edition of Isabelle (I don't think I'm going to ever get it though).
Aw... I'm sorry to hear that about your trades. >< I guess that's the risk that we all have to be willing to take when trading with people online. :/
