True. A fantasy game is meant to have fantasy cards.... however it's not always a good idea to have a bottlecap on imagination. The said card in the crucible was (hopefully) not meant to be offensive and rather encourage new strategies. Also, people can misinterpret things sometimes and become offended on opinions that never existed.
That being said, animals have rights too, but we need to eat. Animals make up a large part of the human diet, and although it may be comparable to cannbalism in some peoples eyes, there are people who consume burgers everyday without second thought. I agree with banning animals from product testing though, with one slight exception in medicine testing - it may cruel, but sometimes there are things we need to test that are too dangerous to test on a human without prerecorded data.
