In the game mode "Casting Fastings" their are two types of players the actives and inactives. Usually the actives want to get rid of the inactives early in the game to make the game go faster, but if you want to use this strategy you will need patience. When you have an alliance instead of nominating and evicting an inactive, target a member in your game that you think is a threat and they won't expect it because they think you will evict the inactive. Also if you do nominate the target and he or she does not get evicted, remember its the start of the game there will be a 1/15 chance of him or her deciding who started to nomination and if he or she does not get evicted it was an inactive so really nothing to worry about. Also one more tip is if you want to have a better chance of getting this plan to work, tell other active members that the person your nominating is targeting them.
