In this scenario an incarnated warforged mated with a dragon maybe the warfoged poly'd into a dragon maybe not as dragons can mate with huminoids. As Dm's does this fly & does it remove two LA's like incarnate template does?
as always moar cheese is better use an incarnated warforged as the huminoid. incarnate construct takes away so much it actually has -la's that cancel out 2 la's but it doesn't affect sub-type so yot get an la'd to hell tauric template for 1 la.
