I only have one real deck, but it measures over 6000!
KO2001 deck setup for listening comprehension and reading comprehension.

I do have a little deck I play with sometimes though, only almost 100 cards.
狼と香辛料 vocab deck, ~15% through book two now.

I threw my big deck away some time ago. It was full of the most basic parts, which was getting out of hand. I now have a smaller, but more potent and manageable deck.

I have only 779 unique kanji in my deck...

Managed to add 31 J-J cards with many new kanjis though, so that number will hit 1000 in no time.

18688 cards.
This was my deck/s (i've reformatted it to put on the server).

We are almost tied.

Good work man. I've had my deck 'completed' for a fair while now (at least since NY day). With only me adding cards every so often (I put any new words I come across in a sticky note list to cover later). So the number of reviews I have to do daily has petered down a lot to a nice 100-150/day which is a welcome change from the 500-700 that it was at its peak.
