MTG Salvation

You could go for a Choices Matter type of deck - Choice of Damnations, Captive Audience, Fatespinner, etc. Give your opponent's nothing but bad choices to make all game.

I was trying to build a Grand Melee style deck a few years ago to force everyone to attack all the time. The opposite version of that would be something like a Silent Arbiter-type deck where you have to carefully choose your attacks/blocks.

While looking for the name of Silent Arbiter, I forgot about Portcullis: yet another card that keeps the field relatively clear but still allows you to utilize your ETB effects.
