To my knowledge, Europe doesnt have any rattlesnakes. They do have vipers though.You might really want to reconsider the fangs and venom, neet as the idea is. Getting bit by a viper is likely certain death.
You might want to consider a constrictor type like a rat-snake. Still deadly, but not instantly fatal. They also tend to be colourfull and are pretty common.
