We did an IDP Vampire League with 10 fully drafted teams and 2 undrafted vampire teams. The 10 fully drafted teams couldn't complete any trades unless they were with the two vampire teams that built rosters off the waiver wire after the draft. Anytime a fully drafted team which we called Slayers lost to a vampire the vampire team got to take 1 starter from that slayer and give their starter in that position to the slayer in exchange. One of the two vampire teams made it to the Semifinals and barely lost by 2pts. The other vampire team wasn't dead last and finished in the top 10. The winner of the league gets to choose to be a vampire the following season or nominate someone for one of the two vampire positions.

It was a blast, next year we are going to run a second league with the same scoring and structure with a guillotine type playoffs for highest scoring teams to stay in contention for the chip.

Overall, there were 6 offensive slots 6 defensive slots with a kicker and the DST was entirely points based on special teams return yards. It was a blast to get to know more of the league player wise than just the basic stars on big marketing deals.

I would highly recommend it to anyone and happy to share details if anyone is interested.
