Killer Bunnies is a card game. It's REALLY fun.
Bunny Bits is a good website to have open when you're playing to clarify some of the rules.
We bought the Blue/Yellow starter for our friend for her birthday. The next weekend we were out buying all of the expansion packs! We like it because there is a certain amount of strategy involved but in the end it comes down to luck so even if everyone picked on your bunnies the entire game the magic carrot could still be yours! My advice is to start simple. Use the blue/yellow decks and play a few times, add in the red and play a few times, add the purple and play a few time etc. Adding all of the expansion packs at once would be VERY confusing. Oh, and the "Guardian Angle", hehehe, love it!
