Teleportig armies

[Viajero]

Easy enough to do for commanders (and their troops) that actually can cast teleporting spells like Gateway, Astral Travel or Stygian Path... but what if I need to teleport more than 1 commander with no teleporting ability aswell? any spell or items that can help me to do that? in the spirit of roleplay why wouldn´t a consenting commander join the army of a commander casting, say, gateway?
