Other cards, such as Sheoldred, Whispering One, can be great for the fact that they continually mess with opponents: old Sheoldred allowed you to return a creature card from your graveyard at the start of your turn, meaning that reanimating her likely nets you free continual reanimation while shes on the field, and ALSO makes your opponents sacrifice a creature during their upkeep, getting around hexproof, indestructible, or other removal resistant barriers
