First wait until your designated Master Builder ( i developed my lover of running to be the Building Maven) when set right next to the Heathen Master is noticed by the believer. Pause the game. Then with two hands ready, click the clock god power, unpause and right after you click that power on your believer and quickly hit pause again. This makes the dust devil stop and you can grab her/him and set him on the Heathen's square to start the race, unpause and watch for some dueling builders!
