Prevents Attack

Prevents Attack is a term for the ability of cards that put an effect on creatures that make them unable to attack.

Details
It is most commonly known by Nariel, the Oracle and its power-based prevention ability, but it can also restrict attacks by civilization or unconditionally to all creatures.

Some cards also have the ability to be not be able to attack themselves or not allowing your other creatures to attack.

There are other abilities such as Tap In (Ryusei Kaiser, the Eternal, removal that triggers on an attack (Super Shachihoko Castle) and Decrease Power on tapped creatures (Necrodragon Zanjibar) that limit your attacking options, but these are not included in the term.

Cards with a Diamond State ability allow you to bypass effects that prevent you from attack.
