From Golden Light They Come

Use this Stratagem during deployment. Instead of placing them on the battlefield, you can set up one ADEPTUS CUSTODES INFANTRY, BIKER or DREADNOUGHT unit from your army in a Godstrike-pattern teleportarium array for 1 CP, or two such units for 3 CPs. At the end of any of your Movement phases these units can teleport into battle – set them up anywhere on the battlefield that is more than 9" away from any enemy models. This Stratagem can only be used once per battle.
