Peter (the Khemri player mentioned at the outset) is guaranteed to see an opportunity to try something new! Makes you think though when you're faced with the unusual, and converting and painting the mini for him was a pleasure.
I took 'flings to Dungeonbowl (105 TR Stars only as 12th man or more) this year with 10 flings, a treeman, Halfling Chef, 1 RR and Morg 'n' Thorg
Lost the first two games then realised getting the ball off Morg is actually quite difficult and reversed the strategy of using him to help the halflings, getting them to screen for him and having him Blitz his way down the pitch. 4 draws later I was wondering if there was any chance of a fling ever landing successfully! Loads of fun though especially the thought of the mighty Ogre being 'protected' by little tubby fellas

.
NOTE to self: Practice with team before going to competition
The year before I took high elves plus Soaren Hightower and no RR figuring if I got my positionals and star in the right place I wouldn't need any. Finished 3/1/2 I think, RR are overated anyway
.....and finally in my old league in Lincoln we had a Chaos Dwarf Team 'manned' solely by Hobgoblins !? I don't remember it being hugely effective but that may well be due to the coaching (or not if he reads this!)
