Lye, with Philomel being what she is with Delath and Veridian, are they permitted on also, with their abilities as detailed in her profile? Would I be permitted to separate them and have them with units, for instance, yet still at their power as stated in her profile?

Also with the special units that are equal to three standard units, I remember last time there was some rule or other about there being allowed only one or two of these types. Is there a limit to how many special units we can have, or what number within those units we can have?
