Its pretty simple, I found it out after i made a mistake in one of my triggers
You can still build around pylon but somewhere in map there will be the aura
| Trigger | 
| Description: | 
| Aura-less Pylon | 
|
| Players: | 
| ¤ Player X | 
| Conditions: | 
| ¤ Always | 
| Actions: | 
| ¤ Move 1 Protoss Pylon For Player X  from Location a To Location b. | 
You can only move 1 pylon per string
So you'd have to do 
Move pylon from location a to b
Move pylon from location c to d
etc.
If you stack the pylons in 1 place and hide it, it would be best
