I love Legacy teams!  These are Blood Bowl teams where lots of people paint an individual miniature, and then there is a raffle and one person wins the whole team. I’ve taken in part in all (I think) the talkfantasyfootball.org teams since 2007, plus various Waterbowl ones, and been lucky enough to win 3, including some spectacularly nice figures.
They are a brilliantly democratic thing, with simple paintjobs and highly intricate ones both getting one vote.  People often contribute figures and then ask not to be included, which is tremendously generous.

The latest?  Waterbowl 2017.  Skaven.  Watch out, here comes Morg!
