Bait and Switch

Been trying to come up with that phrase that describes something like a tease. Something like a give and take away. Something like a game. Something like dangling a carrot over a rabbit. Something like a show. Something trying to get in and destroy. Something like a trick. Something wishy washy. Something tender on top but stone inside. Something that stirs the pot then overturns it. Something that pushes the right buttons to keep the game in play. Something that takes advantage of the truth but can't believe in it.

This thing I'm trying to describe, I don't know it. Yet I do. But I don't understand the point of it.

The point of the tease is to control. But why? 

The stone that the builder refused, will only become the head cornerstone.
