Pin 3 I have a summoner with 1 monk 1 huntress guardian pet.
Pin 1 fill in the rest with summoners with guardian pets, if you decide to use a TB monk he sits at pin 1 aswell.
Green bars are for optional orc minion walls (6 mages total.) And the pin 3 walls are a semi circle around the build, be careful how close they are to core and towers.
