Build is consistent and I have no problems with it.
First wave build auras, both buff beams, pylon (make sure its touching both aura stacks and then the 6 LT's. Switch to your builder squire after building everything.
Starting first combat wave it is very important to max the pylon as quick as possible and then the buff beam. Drop mana to squire to build the 6 mortars and enough to build the 2 golems next wave.
After that just upgrade everything.
Final wave I use tb, and 3 squires. Bring builder squire obviously and whatever others you want after.
