Hey, I am just starting a harlequin army, and was wondering if there is any way I can include my void dragon phoenix in the army (without cheating). It is a heavy support choice for an eldar army. Does this mean I can take it as an elite choice for harlequins, or use the army detachment rule (which i don't know, if someone could explain it to me it would be appreciated). Anyways is there anyway way to include an eldar void dragon phoenix in a harlequin army?
