This is one of those decks that I'm just building to have a fun deck. It is not meant to really win, if I can manage that, I'll be surprised.
So far, there are only so many cards that are either rabbits or feature rabbits. The ones I've collected so far are:
Rabbits
Vizzerdrix
kezzerdrix
jackalope herd
zodiac rabbit
Featuring Rabbits:
Fear 5th or 6th ed only
polymorph
mise
when fluffy bunnies attack
So far the Deck is looking to be B/G/U.
The question though is what other cards have rabbits in them? After that will be tuning it up to actually do something.
