So us here at Olde World Games in Vacaville CA thought the idea of "Who's your boss?" (http://privateerpressforums.com/show...%27s+your+boss) tournament was really cool. So we went to try to set something up. Now, ours was nowhere near as grand as the link posted, but we still had great fun.
We put each of the warcaster/warlock cards in a thick sleeve with a colored back and had a massive deck, and while we didn't have ALL of the warcasters or warlocks, we came pretty close. We then set out them all on a counter and the day began.
Since you didn't have to pay to play in the event, for a quarter, you could redraw from the deck if you didn't like the card you got, and this was going towards a fund for more terrain for the store! Along with this was raffles for things such as template sets or in-store credit. Those were really the only rewards we offered, but next time we may think of more things to do.
Oh, and here is my lists, we only did 35 points rather than 50, and everyone got +6 warjack/warbeast points.
