Er ist ein sehr lustiger Clown.
I am confused by the above sentence. Why is "lustiger Clown" in nominative case? I think it should be einen lustiger Clown because "lustiger Clown" is the object of ist.
Am I missing something?

They take a predicative, which is a description of the subject, and thus, has to be in the same case.
In German, you have to learn for each and every verb which cases it takes. The majority of verbs take an accusative object and may take an optional dative object, but there's also verbs which take no accusative object but only an optional dative object, some verbs which take accusative and optional genitive, some verbs with genitive, and some verbs even have two accusative objects. And, there's also those verbs which take predicatives, either in nominative or caseless.
