If that's the case:
I'd like to nominate the following:
Asmodeus - uses deathrattle viper from D&D, it's about $0.50 for a hero from fiction that we all love and fear equally - "look into my eyes and I will show you eternity..."
Blood Raptor -a fair substitution for Swogs and a good unit on their own, uses bloodseeker drake from D&D, also about $0.50
Gordyrr - Golden Dragon hatchling for Jandar, but not the cheapest figure, about $10.00
Swarm Gruts - A NEW ORC SQUAD, and all you need is BLADE GRUTS!
Einar's Centurions, their playability is an enigma to me at the moment, but it sounds like fun, just sub in a squad of Romans!
5 Easy, cheap custom units that all fit perfectly in HS! Some may use D&D figures, but they are FAR from D&D units.
