I really wish I had heard about this league sooner so that I had more time to prepare for it. I have already downloaded the current rulebook and I am quickly reading through it. As for my Orc team, all I have for it is just the plastic models that came with the box set (2 throwers, 2 Blitzers, 2 Black Orc blockers, and 6 linemen). That may be enough for the league, but if not I may need to order some more players from my LGS (including some of the cool, albeit nasty, Orc cheerleaders).
In addition to the plastic Orc and Human teams that came with the boxed set, I have also acquired a Chaos team and a High Elf team from former players I knew, but I will not be using them for this league.
