You want an ability or a dummy unit that when cast/trained, spawns a unit from a list, yeah?
You need 2 triggers, one to set the group and one to detect the spawning.

• randominit
• Events
  • Map initialization
• Conditions
• Actions
  • Set RandomUnit[1] = Wisp
  • Set RandomUnit[2] = Footman
  • Set RandomUnit[3] = Frost Wyrm
  • Set MaxRandomUnit = 3

And so on, adding more units as you like and setting MaxRandomUnit to how many you added.

• Events
  • (Either)
  • Unit - A unit finishes Training
  • Unit - A unit starts the effect of an ability
• Conditions
  • (Either)
  • (Unit-type of (Triggering unit)) Equal to RandomUnit
  • (Ability being cast) Equal to RandomAbility
• Actions
  • Set integer = (Random number between 1 and MaxRandomUnit)
  • Set point = (Position of (Triggering unit))
  • Unit - Create 1 RandomUnit[integer] for (Owner of (Triggering unit)) at point facing Default building facing degrees
  • Custom script: call RemoveLocation(udg_point)
